It contains hundreds of font families sorted by visual similarity into a visual family tree. Without any previous knowledge about typography, and using only visual criteria, you can navigate directly to 6 font designs of similar style by tapping your iPhone twice. You can do this without knowing the name or style category of the desired font, but can learn these by playing around with the application. FontShuffle 1.0 is free of charge and available in English and German language versions.

2. cliqcliq Colors

If you’re a designer or developer working with CSS, HTML, Flex, Flash, Objective-C or other media-centric technologies, you’ll spend a good amount of time finding the exact colors you want to use and converting between various scales and formats. With cliqcliq Colors, you can create palettes based on colors you like best and quickly convert between RGB, HSB, and CMYK as well as integer and floating point scales. Instead of having to load an entire desktop application or yet another browser tab with a color version website, you can simply pick up your iPhone and get started with Colors!

3. Palettes Pro

Palettes Pro is a powerful productivity tool for creating and maintaining color palettes. Great for creating color schemes. Now you can create a color palette anywhere at anytime. Quickly find matching colors with support for many different color schemes. You may create and store any number of palettes.

4. The Typography Manual

The Typography Manual is a pocket resource for graphic designers and anyone that works with type. It provides all the essentials of a book reference on your iPhone or iPod Touch! The Type Manual features a 60+ page book covering the history of type, type basics, how to properly set text and special characters, typography on the web, graphic design topics, and more. The Visual Type Anatomy Glossary is a 100+ glossary of type terminology that doesn’t just give you a definition, it shows you on the letters themselves.

In simplest of applications ,the program code would make a function call to request a service,from either other Os servers/frameworks ,I/O Devices,timers,DMA etc.This service can be performed either synchronously or asynchronously.In a synchronous method the service returns to the caller function with a status of completion (typically success or failure).While the service completes the caller thread is in a blocked mode waiting for completion.In an asynchronous call ,the request is submitted and the control returns to the caller.The completion of that request occurs sometime later.In the meanwhile the caller may perform other tasks and is not in a blocked state.upon completion the caller receives a signal indicating the completion of the request.Now the caller threads handles the result of the completed request.This signal is known as the event and the code is said to be event driven.

Even-driven multitasking

Events can come from external sources,such as UI inputs ,hardware sources,network sockets and also from completed asynchronous requests.Events are managed by event handlers ,which ,as its name suggests,waits for an event and then handles it.Typically the hardware running Symbian or iOs, or for that matter any other RTOS would have far less resources than a typical PC.Thus the operating system needs to have a efficient event handling model to have minimum turnaround time to events as well as prioritize them in desired order.Also between events the system should be a low power state to save on the power consumption.This avoids constant polling, which leads to significant power drain and should be avoided on a battery operated device.

Runloops in iOS and Active Schedulers in Symbian provide a model for lightweight ,event-driven multitasking within the same thread.

Active objects/Active Scheduler:

Active Scheduler is the indefinite runloop which runs inside a thread .Active objects symbolize the requests which are added to the scheduler and get serviced accordingly.

Active objects encapsulate the traditional wait loop inside a class.They were designed such that the switch between the active objects running within a thread incurs a less overhead than context switching of threads(Moreover space overhead for a thread is minimum 4kb on the kernel side and 8kb user side).This makes active objects the most preferable for event-driven multitasking in Symbian.

Active scheduler is a infinite run loop which runs inside a thread,with methods to start and stop the loop.Once started this loop schedules the active objects within the thread.Typically, a Symbian OS thread has a single Active Scheduler. As mentioned above, that Active Scheduler is responsible for managing all active objects belonging to the thread.It is worth noting that the Active Scheduler schedules active objects in a non-pre-emptive way so that one active object cannot interrupt another while that is running. This is in contrast with thread scheduling (even in Symbian OS), since the execution of one thread can be pre-empted at any given time by another thread.

Representation:

Active Objects encapsulates: A data member representing the status of the request(iStatus). A handle on the asynchronous service provider. Connection to the service provider during construction. The function to issue(or reissue) the asynchronous request (user-defined) The handler function to be invoked by the active scheduler when the request completes( RunL() ).This function can be more appropriately called as the event handler for clarity. The function to cancel an outstanding request( Cancel() ).

The above figure shows the process of submitting a request to an asynchronous service provider ,which generates an event on completion.

Explanation:

1.Request is posted to asynchronous service provider.

2.Having issued the request the issuer must call CAtive::SetActive().This sets the active objects iActive flag.

3.The request provider changes the value of the iStatus as KRequestPending.

4.The active scheduler checks the iActive and the iStatus to know that a particular active object has a request pending.

5.Once the request is completed the service provider calls the User::RequestComplete(),passing the completion result in the iStatus.

6.The active scheduler now calls the handler function (Runl()) for the active object and clears the iActive flag for the same.

7.The handler function handles the event.

Runloops(CFRunloop) in iOS

A run loop is essentially an event-processing loop running on a single thread. The RunLoop is what keeps your app running until it should quit.You register potential input sources on it, pointing it to the code that it should execute whenever input is available on those sources .

Then when input comes into a particular source, the run loop will execute the appropriate code, then go back to waiting for input to come in again to any of it’s registered sources. If input comes into a registered source whilst the run-loop is executing another piece of code, it’ll finish executing the code before it handles the new input.The scheduling is non pre-emptive and analogues to the way the active scheduler schedules the requests.

In all its simplicity it can be described as a glorified form of :

while(true){ HandleEvent1(); HandleEvent2(); }

The job is to process events which arrive from elsewhere.User needs to write code to handle these and the OS takes care of all the other things like scheduling,receiving and sending them.The level of abstraction at which the user interacts with the OS is higher than in Symbian ,resulting in fewer things to be done by the user and the OS taking care of the rest.There is exactly one runloop per thread and the user cannot create or destroy the same.

Example showing ,how to hook up a socket with the current runloop

CFRunLoopRef currentRunLoop = CFRunLoopGetCurrent(); //This gets the current run loop

CFRunLoopSourceRef runLoopSource = CFSocketCreateRunLoopSource(kCFAllocatorDefault, listeningSocket, 0);

//Event source is created with the listening socket.

CFRunLoopAddSource(currentRunLoop, runLoopSource, kCFRunLoopCommonModes);

//This event source if finally now added to the run loop

Now whenever there is a connection request on the socket the run loops calls the serverAcceptCallback() which is the callback function for the listeningSocket. Following is a comparison between Symbian and iOS.

Symbian

• Active Scehduler
• CActiveScheduler::Add(instance of the active object)
• HandleEvent – RunL()
• CActiveScheduler Start()

iOS

• CFRunloop
• CFRunLoopAddSource(Source for the event)
• Callback function for the above event source.
• CFRunloopRun()

Limitations of event-driven multitasking in a single thread:

We have seen that in both cases the handling of events is non pre-emptive in the way they are scheduled by the active scheduler or the runloop.So if the event handler code is something which would take lot of time to complete ,in such a scenario the main thread would become un-responsive and the loop would wait for the particular event handling to get over.In such scenarios multithreading is a better option.

1. Beginning iPhone Development: Exploring the iPhone SDK

I hope you’ll find these books useful in iPhone application development. Do provide us your reviews in the comments section. :)

As iOS developers, we have some hard choices to make when we consider which devices to focus on as we develop our apps. Though many of you will shrug this off and point to universal builds as the key to the big time, that’s a far too obvious approach, and you’re probably shaving off huge chunks of the user experience by creating a one-size-fits-all app. One size may fit all, but it’s rarely a good fit.

One of the most striking differences between iPad and iPhone is the screen estate, and the implications for interface-conscious developers – which we all should strive to be – are tremendous. While the screen area for iPhone/iPod touch measures 10.4 inches (4.54” x 2.3”), the iPad screen enjoys a full 71 inches of area (9.56” x 7.47”) – almost 8 times bigger! Think of it like building a home: with just a small plot of land you’ll focus on the essentials: bedrooms, kitchen, living room, bath… certainly no spare room. But given a bigger plot you‘ll want to add a garden, a couple of parking spaces, and for sure build in that spare room. The same principle applies to iPad vs iPhone in terms of the user experience on offer with these very different screen sizes.

On iPhone, the smaller screen area dictates a pretty minimal interface for your app, whereas on iPad there are amazing opportunities with the more generous area. That being said, for certain apps the same interface on either display may be comfortable for users, especially apps built primarily for media or information consumption. For example, an app like Night Stand shares almost the same user interface on iPhone and iPad, and has been a spectacular hit on both. Why? Well, for starters it’s gorgeous. And ingenious programming doesn’t hurt, either.  But also, once a user configures Night Stand it’s essentially an information consumption application (though the latest version brings in some more user-intensive features). Also, there’s one big exception with Night Stand for iPad, and that’s a new, iPad-only theme – one significantly awesome theme that really, REALLY shines on the big screen. But awesome themes notwithstanding, Night Stand still very much follows an app-to-user orientation; the user is still passive.

So while Apple will most likely put iPhone and iPad on the same track of iOS in the very near future, developers ought not assume that these devices are the same in terms of UX, or that users have the same expectations toward iPad and iPhone apps. Nope, expectations are growing increasingly different as each day passes, and the gap is only widening.

Just a few days ago we were watching Toy Story on the iPad, and it was a cinematic experience in miniature with the lights dimmed and munching on some snacks. Two people huddled around an iPhone watching a film for 90 minutes!? Not unthinkable, but certainly none too appealing. No doubt, iPhone is much better suited to snagging a glimpse at Facebook, tapping out the odd Tweet, light email, checking your schedule, that kind of stuff. I tend to use my iPhone in bursts, to get or give info as quickly as possible without going into details, whereas iPad can offer an immersive media consumption experience, like watching a full length film in style. When I browse the App Store for iPad games and applications, I look for things I can be time-intensive with. (And I’m not alone.) When I shop for an iPhone app it’s usually for a cool little game, or the latest social networking app to stay connected with my people. And yeah, isn’t that what a phone is made for in the first place: to keep in touch with friends and family? Now if I can do that, plus spend 30 – 40 mins playing puzzles or doodling or something, well, all the better!

Note the Productivity category, with iPad sales far outweighing iPhone. Business, finance, education, and anything reading-related are also natural fits for iPad.

So developers, before you start building your next app take some time to decide whether it best suits iPhone or iPad – or both. And if both, then how to differentiate. iPhone/iPod touch has a user base of almost 100 million compared to just over 3 million for iPad, but there are over 200 thousand apps for iPhone and just a few thousand for iPad. Getting noticed in the sea of iPhone apps is not so easy, but if you optimize your universal app for iPad (or develop exclusively for iPad) along the lines of what we’ve been discussing it’s far easier to make a splash.

While all this was going on, of course there was some big news on June 7, when Steve Jobs introduced yet another Apple engineering marvel: iPhone 4.  Bundled with new features like front-facing camera, superior rear camera, dual mikes for increased noise cancellation, eye-popping Retina Display, multitasking, 720p HD video recording and even a new kind of gyroscope technology, iPhone 4 is a huge evolutionary step in smartphone design.  As the tag line says: “This changes everything.  Again.”  And, marketing hyperbole aside, as far as day-to-day use is concerned for sure this will change the way we use iPhone.

Before this year’s launch, several leaked – or mislaid – iPhone 4 models made the rounds of the major tech blogs, complete with gory dissections and the standard tsunami of specu-babble.  But there was one stealth feature all the teardowns and pundits failed to even guess at: the gyroscope.  And on our side, as veteran iPhone developers, when Steve Jobs announced this during WWDC we were all pretty excited.  And while it still hasn’t gotten much attention in the press, this feature is a game changer in iPhone’s rivalry with Android and Symbian devices.

Apple’s been pioneering smartphone innovations since iPhone’s introduction in 2007 with many widely imitated micro-technologies, in particular the accelerometer.  The accelerometer is a type of sensor that detects changes in a device’s orientation, vibration, rotation or fall by detecting linear acceleration along one of the three X, Y and Z axes – that is: up/down, right/left, and front/back.

3-axis accelerometers enable features we by now take for granted in smartphones (and lately, too, in non-Apple branded consumer digital cameras, music players, and gaming peripherals).  For example, landscape/portrait orientation shifting, tilt for directional control in games and applications, and shake features for refreshing a webpage or shuffling a playlist.  The 1st generation of accelerometer – pre iPhone 4 – could measure only linear motion; it couldn’t sense direction on a compass or twisting motions or rotation, nor had any notion of gravity.

Then last year Apple added a magnetometer to the iPhone 3Gs, enabling it to sense magnetized direction relative to the Earth’s poles. And now, with the introduction of the gyro in iPhone 4, Apple once more ups the ante in spatial detection / orientation with a new sensor for detecting 3-axis angular acceleration around the X,Y and Z axes, enabling far more precise virtualization of pitch, yaw and roll on iPhone.

While detection of change in velocity has been possible for some time thanks to conventional accelerometer calculations in terms of linear acceleration, the gyroscope has been designed to detect angular acceleration, which will detect change in both velocity and direction at the same time.  iPhone 4’s gyroscope enables the sensing of even slight degrees of rotation while simultaneously rejecting linear movements and hand jitters – both still ably handled by accelerometer’s linear movement detection technology.

Combining the 3 axes of the gyroscope along with the 3 axes of the accelerometer now enables iPhone to recognize distance, speed and direction as it moves real-time through space. And thanks to the CoreMotion APIs in iOS, developers with the vision to make use of gyroscope data can access it freely, as some have already done.

Of course iPhone 4 already includes gyroscope support, but it’s a safe bet the gyro will be baked into future versions of iPod touch, and naturally, iPad.  iPhone devs who can make use of this amazing new technology will find opportunities aplenty on the new platforms, especially games producers and developers.

update:  Death Star or iPhone gyroscope?   iFixit has the goods.

True, iPhone 4 had been dissected, diagrammed and reported on ad nauseam even months before Jobs’ announcement, but that didn’t dampen our enthusiasm on release day. And despite the leaks coming out of Vietnam and hands-on time with stolen prototypes, what the prophets couldn’t prognosticate was how deliciously the hardware gooses the software.  Just consider iOS itself.  It’s a huge lift for developers, a massive gift from Apple for anyone with an eye to publishing for the App Store.

The first turn-on in iOS is multitasking, which depending on your application type can be achieved through one of 7 core background services Apple provides: background audio, voice over IP, background location, push notifications, local notifications, task completion and fast app switching.

The upshot of this is users will genuinely feel they’re multitasking, while the software is actually only running one app at a time, albeit with services.  So in terms of raw power that developers can exploit and direct toward their apps, we have the lion’s share of CPU, memory and other resources at our disposal.

Aside from multitasking, we also now have Game Center with integrated social networking, and this is going to change the gaming experience on iPod touch and iPhone forever.  And with the introduction of iAd, developers now have another revenue model with the potential for ad-supported apps distributed at no charge to users.  User reaction to in-app advertising has yet to be tested, but we’re already testing various configurations.

The introduction of app-specific location settings also means you don’t need to change your location each time you use a new application that requires setup with different locations.  The ability to gift apps is another nice feature with terrific upside for developers.

What else have we got to look forward to… ah yes, Spotlight now not only searches your device, but also the Web and Wikipedia.  In-page video playback for Safari is another lovely addition.  And iPhone 4 is now more enterprise-friendly with enhanced data protection, mobile device management, wireless app distribution and SSL VPN support. Wake on wireless, too, automatically re-connects you when your lost wireless connection is regained.  Places in photos offers other interesting possibilities and Mail has been completely revamped.

Spotlight with Web & Wiki search

Coming to the SDK, full map overlays means developers can implement a transparent map layer on top of screen contents, a boon for location-oriented utilities, games, and lifestyle apps.  And the AV Foundation framework for the first time gives developers full control over video playback and capture.  Full photo library and calendar access now gives developers the power to directly access these previously semi-restricted features.  Now, too, you can send short messages via your apps through in-app SMS, and Accelerate provides easy to use functions for your computational / number-crunching needs.  Another welcome addition are the Quick Look APIs, similar to OS X’s desktop version, giving users the ability to page through documents and other filetypes without needing to launch an app. The UIAutomation instrument, too, can be made to automate touch events, while Time Profiler and Energy Diagnostics Instruments can be used to fine tune your applications.

All these new SDK-side features represent a huge opportunity for iPhone developers to not just tack on new feature to existing apps, but to dream up entirely new creations and markets.  iOS and iPhone 4 mark another exciting chapter in Apple’s handheld lineup.  We can’t wait to show you what we’ve got in store.

pre-iPad

When Apple announced the iPad in January this year, we were as excited as the rest of the development community: new Apple products mean new opportunities to build our brand and make cool stuff that earns big monies for our partners and ourselves. Speaking in broad terms about our reaction to any new Apple product, we don’t microfocus on tech specs. We home in on the user experience, the operating environment and the implications for end users of our applications. The guiding principle is this: iPad and iPhone are not just the latest iterations of a cellphone or tablet PC, but entirely new experiences of technology, media creation and consumption and every piece of software we make for them should reflect or expand on these qualities. That’s the chief responsibility of our iPhone and iPad developers. So come January 27, first things first, we began drilling into the new SDK, day and night, all the while following every last bit of news and opinion coming out about iPad.

Screen

When it was announced that existing iPhone apps would be able to run without any glitches on the iPad, straight from the App Store, we were all pretty relieved. But then we saw the fine print: displaying an iPhone app centered at the much smaller native iPhone resolution or in pixel-doubled form looked and felt – well, crappy. The large screen was a pleasure on the one hand, especially for intensive apps and games with more space for controls and real-time status updates without interrupting workflow/gameplay. But on the other hand, we must be wary of presenting users with needless distractions, potentially confusing distractions, all the while achieving a certain level of tautness so the interface doesn’t look slack or empty.

UI Changes

The first iPad SDK (actually iPhone SDK 3.2) offered some great UI enhancements over iPhone, such as pull down menus and the newly added Master-Detail view. Added to this, iPad’s contextual menus are great at keeping the UI out of the way, displaying only the content and controls that are relevant to the user at the relevant moment. Bezier Path, originally part of the Mac development environment, has found a place in iPad SDK, helping us to create drawings much more easily. PopOverController, too, with its built-in animations, lessens the creative burden on our iPad dev team to a great extent.

A Pressing Invitation

While we were busy exploring the new SDK, we were happily surprised by an email from Apple notifying us that the App Store was already accepting and approving apps for iPad launch day. Initially we were skeptical about how to proceed as (unlike some developers) we didn’t have a hardware sample to run trials with and the time frame for release was less than a week. But there’s no way we were going to miss out on the grand opening of the iPad App Store, so we began brainstorming a port of one of our most successful iPhone applications to the iPad. With the senior members of our iPhone development team now on board, we immediately began redesigning and engineering the updated app for iPad.

Details, Details, Details

One thing for iPad developers to keep in mind is that every UI element supports two orientations: landscape and portrait. It was blissfully new to us at the time, and the design team responded with some awesome, first-ever iPad wireframes and gorgeous new graphics in no time flat. And as complex and tough as it was getting the functionality right, we spent even more time tweaking the UI to make it pixel perfect.

When developing for the Mac, resolution independence is a constant theme throughout the development process, but for those of us employing Rapid Application Development on iPhone, resolution independence was not a factor we were used to considering. Now, porting those iPhone apps to iPad, we find we’re spending a lot of time scaling the UI to iPad’s screen. While this has gone down internally as an enormous pain in the ass, it’s also given us a chance to revisit the graphics in our ‘greatest hits’ apps and improve them, something any good designer – and end users – can surely appreciate. And the fact that our first application for iPad is still in the Top Paid Apps section, has been staff picked by Apple, and featured as a Top 10 Must-Have iPad App by Engadget – yeah, that’s more than made up for the effort. ;) And now that we have the hardware in the flesh to tool around on, we’re doing even more polishing of our initial releases, and soon we’ll start releasing our first 100% start-to-finish iPad-optimized apps and we promise a much BIGGER experience than before.

Liftoff

Despite starting work on our port just a few sleepless days earlier, on April 1^st Apple started listing the first iPad apps on the App Store, and the very next day our app was spotlighted in the Showcase. Today, I hold the iPad close to my heart; I see our apps running smoothly and the display makes them look even better, all thanks to our talented developers and the tireless work of the user interface design team. When you look at the most successful apps in the App Store it’s the simple ones that succeed and have legs. ‘Keep it simple,’ the saying goes. And it’s true. The iPad App Store is still in its infancy, and this is the time to make your mark. If you’ve been mulling over even the simplest idea, who knows how it may turn out!? Drop a little hello our way and let’s see where it takes us!

That Screen

Text Formatting Popover

Good iPhone app development aims for a stripped down UI due to the quick-to-clutter, pocket-
sized screen canvas. Rather than creating screenfuls of switches and check boxes, iPhone developers have typically built layers of menus, creating a vertical hierarchy of sometimes branching, confusing commands. While this has been the norm on iPhone, this is anathema to good iPad development.

The big deal on iPad is the big screen. This, combined with iPad’s new UI features, allows developers to offer on-screen controls much like a traditional Mac or Windows application.

Navigation Bars, Popovers, and the Edit Menu

iPhone developers coming to iPad will soon realize they can utilize the top navigation bar as a fixed toolbar, much like traditional, non-mobile applications. Thanks to iPad’s generous screen space, the top navigation bar / toolbar offers enough button space for the main controls that

Color Picker Popover

users have come to rely on in traditional applications, especially in landscape mode. Whether word processing or editing images, users should be able to work on a single screen for an entire session, just like on a regular computer.

On iPhone, users often jump back and forth to reach essential off-screen options and functions, but on iPad contextual controls are introduced not by forcing the user away from content, but instead with nav bars, edit boxes and popovers that allow users to linger on the main screen as they edit.

New Challenges
Application development for iPhone has been an utterly novel experience, with thousands of worldwide developers slowly coming to terms with multi-touch UI principles for a pocketable device. Now with iPad, Apple is challenging us once more to create the first generation of powerful, full-spec’d applications for full-sized multi-touch. If we do this right, the notion of iPad as somehow being derivative will quickly vanish as the platform comes into its own.
