DEVELOP FOR IOS



Develop for iOS

The world’s most advanced mobile platform.

iOS is the world’s most advanced mobile platform, constantly redefining what’s possible on a mobile device. Using the iOS SDK and Xcode, it’s easy to create amazing apps. Store documents and key value data with iCloud. Publish magazines and newspapers with Newsstand. Quickly integrate core Twitter functionality in your app. Stream audio and video content in new ways with AirPlay. With hundreds of millions of iOS users just a tap away on the App Store, the possibilities are endless.

Powerful Foundation

The amazing user experience of iOS is possible because of the powerful foundation upon which it is built. Derived from the proven core of OS X, iOS has been streamlined to be compact and efficient, taking maximum advantage of the iPad, iPhone and iPod touch hardware. Technologies shared between iOS and OS X include the OS X kernel, BSD sockets for networking, and Objective-C, and C/C++ compilers for native performance.

Cocoa Touch

Cocoa Touch is the programming framework driving user interaction on iOS. Using technology derived from Cocoa and the gorgeous Mac desktop, Cocoa Touch and the iOS interface were completely re-designed for multi-touch. Buttons, table lists, page transitions, and gestures on the iPhone are unique for the pocketable form factor, and all this UI power is available to developers through the Cocoa Touch frameworks.
Built upon the Model-View-Controller paradigm, Cocoa Touch provides a solid foundation for creating state-of-the-art applications. When combined with the Interface Builder developer tool, it is both easy and fun to use drag-and-drop to design the next great iOS application.
Strong low-level foundations enable fantastic high-level frameworks such as Game Kit for multiplayer gaming, Core Data, which offers high performance, yet easy-to-use data management, Core Animation for stunning effects, and the most innovative browser engine on mobile devices in WebKit.
Working together, the Cocoa Touch frameworks and powerful foundation provide a truly unique canvas upon which to create a new work of application art. Learn more

Graphics

The iOS delivers a wide-range of graphics capabilities, ranging from comprehensive 2D drawing to accelerated 3D rendering and direct access to the system’s video playback and capture capabilities. Accessible through high-level frameworks, these capabilities make it easy to create gorgeous animations and transitions within your application’s UI. Learn more

Easy to Get Started

The complete Xcode developer tools and iOS SDK are distributed together, available as a free download simply by registering as an Apple Developer. Your first application will be running in the Simulator within minutes of installing the toolset, and when you are ready to test and deploy on an iPad, iPhone or iPod touch, the iOS Developer Program will guide your way.

[edit]Common software platforms

See also: Comparison of Android devices, List of BlackBerry products, List of iOS devices, Comparison of Symbian devices, and List of Windows Phone devices
The most common mobile operating systems are:
Android from Google Inc.[29] (free and open source)[30]

The Galaxy Nexus running Android 4.0.1
Android was developed by a small startup company that was purchased by Google Inc. in 2005, and Google continues to update the software. Android is a Linux-derived OS backed by Google, along with major hardware and software developers (such as Intel, HTC, ARM, Samsung, Motorola and eBay, to name a few), that form the Open Handset Alliance.[31] Released on November 5th 2007, the OS received praise from a number of developers upon its introduction.[32] Android releases prior to 2.0 (1.0, 1.5, 1.6) were used exclusively on mobile phones. Most Android phones, and some Android tablets, now use a 2.x release. Android 3.0 was a tablet-oriented release and does not officially run on mobile phones. The current Android version is 4.0. Android releases are nicknamed after sweets or dessert items like Cupcake (1.5), Frozen Yogurt (2.2), Honeycomb (3.0), and Ice Cream Sandwich (4.0). Most major mobile service providers carry an Android device. Since the HTC Dream was introduced, there has been an explosion in the number of devices that carry Android OS. From Q2 of 2009 to the second quarter of 2010, Android's worldwide market share rose 850% from 1.8% to 17.2%. On 15 November 2011, Android reached 52.5% of the global smartphone market share.[33]

The Apple iPad tablet computer uses a version of iOS.
BlackBerry OS from RIM (closed source, proprietary)
This OS is focused on easy operation and was originally designed for business. Recently it has seen a surge in third-party applications and has been improved to offer full multimedia support. Currently Blackberry's App World has over 50,000 downloadable applications. RIM's future strategy will focus on the newly acquired QNX, having already launched the BlackBerry PlayBook tablet running a version of QNX and expecting the first QNX smartphones in early 2012.[34]
iOS from Apple Inc.[29] (closed source, proprietary, on top of open source Darwin core OS)
The Apple iPhone, iPod Touch, iPad, and second-generation Apple TV all use an operating system called iOS, which is derived from Mac OS X. Native third party applications were not officially supported until the release of iOS 2.0 on July 11th 2008. Before this, "jailbreaking" allowed third party applications to be installed, and this method is still available. Currently all iOS devices are developed by Apple and manufactured by Foxconnor another of Apple's partners.
S40 (Series40) from Nokia (closed source, proprietary)
Nokia uses S40 OS in their low end phones (aka feature phones). Over the years over 150 phone models have been developed running S40 OS [35]. Since the introduction of S40 OS it has evolved from monochrome low resolution UI to full touch 256k color UI.
Symbian OS from Nokia and Accenture[29] (open public license)

The Nokia N8 running Nokia Belle(Symbian OS 9.5.2)
Symbian has the largest smartphone share in most markets worldwide, but lags behind other companies in the relatively small but highly visible North American market.[36] This matches the success of Nokia in all markets except Japan. In Japan Symbian is strong due to a relationship withNTT DoCoMo, with only one of the 44 Symbian handsets released in Japan coming from Nokia.[37] It has been used by many major handset manufacturers, including BenQ, Fujitsu, LG, Mitsubishi, Motorola, Nokia, Samsung, Sharp, and Sony Ericsson. Current Symbian-based devices are being made by Fujitsu, Nokia, Samsung, Sharp, and Sony Ericsson. Prior to 2009 Symbian supported multiple user interfaces, i.e. UIQ from UIQ Technologies, S60 from Nokia, and MOAP from NTT DOCOMO. As part of the formation of the Symbian OS in 2009 these three UIs were merged into a single OS which is now fully open source. Recently, though shipments of Symbian devices have increased, the operating system's worldwide market share has declined from over 50% to just over 40% from 2009 to 2010. Nokia handed the development of Symbian to Accenture, which will continue to support the OS until 2016.[38]

The Palm Pre running HP (formerly Palm)webOS. HP purchased Palm in 2010.
bada from Samsung Electronics (closed source, proprietary)
This is a mobile operating system being developed by Samsung Electronics. Samsung claims that bada will rapidly replace its proprietary feature phone platform, converting feature phones to smartphones.The name 'bada' is derived from 바다, the Korean word for ocean or sea. The first device to run bada is called 'Wave' and was unveiled to the public at Mobile World Congress 2010. The Wave is a fully touchscreen running the new mobile operating system. With the phone, Samsung also released an app store, called Samsung Apps, to the public. It has close to 3000[39] mobile applications.
Samsung has said that they don't see Bada as a smartphone operating system, but as an OS with a kernel configurable architecture, which allows the use of either a proprietary real-time operating system, or the Linux kernel. Though Samsung plans to install bada on many phones, the company still has a large lineup of Android phones.
Windows Phone from Microsoft (closed source, proprietary)
On February 15th, 2010, Microsoft unveiled its next-generation mobile OS, Windows Phone. The new mobile OS includes a completely new over-hauled UI inspired by Microsoft's "Metro Design Language". It includes full integration of Microsoft services such as Windows Live, Zune, Xbox Liveand Bing, but also integrates with many other non-Microsoft services such as Facebook and Google accounts. The new software platform has received some positive reception from the technology press.[40][41][42]

[edit]Other software platforms

webOS from HP (certain parts[clarification needed] open sourced)
webOS is a proprietary mobile operating system running on the Linux kernel, initially developed by Palm, which launched with the Palm Pre. After being acquired by HP, two phones (the Veer and the Pre 3) and a tablet (the TouchPad) running webOS were introduced in 2011. On August 18th, 2011, HP announced that webOS hardware is discontinued[43] but HP will continue to support and update webOS software and develop the webOS ecosystem.[44] HP plans to open-source webOS in the future.
GridOS from Fusion Garage[45]
GridOS was built using open source code from the Android kernel.[46] It is used as the operating system of the Grid 4 mobile phone and Grid 10 tablet.
Mer project (community-driven)
Mer is an open, mobile-optimised, core distribution aimed at device manufacturers; powered by Qt/QML and HTML5 – openly developed, inclusive, and meritocratically governed.
BlackBerry Tablet OS from QNX Software System/RIM[29] (closed source, proprietary)
BlackBerry Tablet OS is based on QNX. QNX is a commercial Unix-like real-time operating system, aimed primarily at the embedded systems market. The product was originally developed by Canadian company, QNX Software Systems, which was later acquired by BlackBerry-producer Research In Motion. This OS is primary for BlackBerry Playbook (tablet).
SHR (community-driven)
SHR is a GNU/Linux based operating system for smartphones and similar mobile devices. It integrates various Free and Open Source Software projects into a versatile platform – flexible enough to run on a vast selection of mobile hardware such as the Openmoko Neo Freerunner, Nokia N900, Palm Pre and variants, T-Mobile G1, HTC HD2, iPhone 3Gs and more. The SHR build system is based on OpenEmbedded – well known from the Yocto project. For telephony, networking, etc. freesmartphone.org framework is used. On top of that an easy to use graphical interface centered around Enlightenment libraries is used to provide phone calls, messaging and pim. A growing amount of available applications offers SHR users with everything expected on a smartphone. But also numerous classical programs well known from other Linux distros can be made available easily.
SHR is 100% community driven and based on Free and Open Source Software. This empowers everybody to realize their innovations or add support for new hardware – without needing to ask some CEO or strategy manager first.[47]
MeeGo from non-profit organization The Linux Foundation (open source, GPL)
At the 2010 Mobile World Congress in Barcelona, Nokia and Intel both unveiled 'MeeGo' a brand new mobile operating system which would combine the best of Moblin and the best of Maemo to create a truly open-sourced experience for users across all devices. As of 2011, Nokia has announced that it will no longer be pursuing MeeGo and will instead adopt Windows Phone as its primary mobile OS. Nokia announced the Nokia N9 on June 21, 2011 at the Nokia Connection event[48] in Singapore. The phone is presumed to become available to the public in September 2011. LG announced its support for the platform.[49]
Linux based operating system (open source, GPL)[29]
Linux is strongest in China where it is used by Motorola, and in Japan, used by DoCoMo.[50] Rather than being an OS in its own right, Linux is used as a basis for a number of different operating systems developed by several vendors, including Android, GridOS, Boot to Gecko, LiMo, Maemo,MeeGo, Openmoko and Qt Extended, which are mostly incompatible.[51][52] PalmSource (now Access) is moving towards an interface running on Linux.[53] Another software platform based on Linux is being developed by Motorola, NEC, NTT DoCoMo, Panasonic, Samsung, and Vodafone.[54]
Brew from Qualcomm
Brew is used by some mobile phone manufacturers and mobile networks, however most often the end-user does not know this since mobile phones running Brew most often lack any Brew branding. Brew runs in the background with the custom "skins" of the mobile phone manufacturer or operator on-top. Brew is used by Sprint Nextel, metroPCS, U.S. Cellular and Verizon in the US and by the Three network in much of Europe, the UK and Australia on many mobile phones produced especially for their network. Manufacturers such as LG CDMA, Huawei, INQ Mobile, Amoi, and Samsung Mobile amongst others use Brew in some of their mobile phones and it is featured in Three UK phones such as the 3 Skypephone, INQ1 and Huawei u7510 (3 Touch). Two of HTC's mobile phones use Brew's successor Brew MP.
LiMo 4 from LiMo Foundation
LiMo Foundation launched LiMo 4 on 14 february 2011, the latest release of the LiMo Platform. LiMo 4 delivers complete middleware and base application functionality, including a flexible user interface, extended widget libraries, 3D window effects, advanced multimedia, social networking and location based service frameworks, sensor frameworks, multi-tasking and multi-touch capabilities. In addition, support for scalable screen resolution and consistent APIs means that the platform can deliver a consistent user experience across a broad range of device types and form factors[55]

[edit]Historical software platforms

Maemo from Nokia (open source, GPL)
Maemo is a software platform developed by Nokia for smartphones and Internet tablets. It is based on the Debian operating system.
Maemo is mostly based on open source code, and has been developed by Maemo Devices within Nokia in collaboration with many open source projects such as the Linux kernel, Debian andGNOME.
Maemo is based on Debian GNU/Linux and draws much of its GUI, frameworks and libraries from the GNOME project. It uses the Matchbox window manager and the GTK-based Hildon as its GUI and application framework.
Windows Mobile from Microsoft[29][56] (closed source, proprietary)
The Windows CE operating system and Windows Mobile middleware are widely spread in Asia. The two improved variants of this operating system, Windows Mobile 6 Professional (for touch screen devices) and Windows Mobile 6 Standard, were unveiled in February 2007. It has been criticized for having a user interface which is not optimized for touch input by fingers; instead, it is more usable with a stylus. However, unlike iOS, it does support both touch screen and physical keyboard configurations.
Windows Mobile's market share has sharply declined in recent years to just 5% in Q2 of 2010.[57] Microsoft is phasing out the Windows Mobile OS to specialized markets and is instead focusing on its new operating system and software platform, Windows Phone.
Palm OS/Garnet OS from Access Co. (closed source, proprietary)
webOS was introduced by Palm in January 2009 as the successor to Palm OS with Web 2.0 technologies, open architecture, and multitasking capabilities.
DangerOS from Danger, Inc. (closed source, proprietary)
DangerOS was a largely Java-based operating system for the Danger Hiptop line of smartphones produced by Danger Incorporated from 2002 to 2010, also sold as the T-Mobile Sidekick. In 2008, Danger, Inc. was acquired by Microsoft.[58] Former Danger, Inc. employees were tasked to work on the Microsoft Kin line of phones, and in 2010 DangerOS was discontinued as a smartphone platform after the Kin phones were released. In 2011 T-Mobile introduced a new smartphone using the Sidekick branding based on Google's Android platform, with no relation to the previous Danger Hiptop phones.[59]
Nucleus from Mentor Graphics (closed source)
Nucleus OS is a real-time operating system (RTOS) and toolset created by the Embedded Systems Division of Mentor Graphics for various central processing unit (CPU) platforms. The Nucleus RTOS is designed for embedded systems applications including consumer electronics, set-top boxes, cellular phones, and other portable and handheld devices. For limited memory systems Nucleus RTOS can be scaled down to a memory footprint as small as 13 KB for both code and data. Manufacturers such as Motorola, Samsung, LG, Siemens/Benq, Sagem, Pantech, and NEC use Nucleus in some of their mobile phones. The last devices released that used Nucleus OS are LG Encore (GT550), LG Prime (GS390), and Pantech Pursuit (P9020).

[edit]Upcoming software platforms

Firefox OS[60] from non-profit organization Mozilla Foundation (open source, GPL)
According to Ars Technica, "Mozilla says that B2G is motivated by a desire to demonstrate that the standards-based open Web has the potential to be a competitive alternative to the existing single-vendor application development stacks offered by the dominant mobile operating systems."[61]
BlackBerry 10 from RIM
BlackBerry 10 (previously BlackBerry BBX) the next generation platform for BlackBerry smartphones and tablets. In other words, there will be only one OS for both Blackberry smartphones and tablets going forward.[62]
Aliyun OS from Alibaba/AliCloud (cloud based)
AliCloud's operating system revolves around the idea of bringing cloud functionality to the mobile platform. According to the company, Aliyun will feature cloud-based e-mail, Web search, weather updates, and GPS navigation tools. In addition, the operating system will synchronize and store call data, text messages, and photos in the cloud for access across other devices, including PCs. Alibaba says it will offer customers 100GB of storage at launch. the operating system would allow users to access applications from the Web, rather than download apps to their devices.[63]
Tizen from non-profit organization The Linux Foundation (open source, GPL)
Tizen is an open source project hosted by the Linux Foundation, with Intel and Samsung leading its development steering group, and support from the LiMo Foundation. According to Intel, Tizen “combines the best of LiMo and MeeGo." HTML5 apps will be emphasized for the new OS, with the MeeGo project encouraging its members to transition to Tizen, stating that the "future belongs to HTML5-based applications, outside of a relatively small percentage of apps, and we are firmly convinced that our investment needs to shift toward HTML5." Tizen will be targeted at a variety of platforms such as handsets, tablets, smart TVs and in-vehicle entertainment. The initial release of Tizen is targeted for Q1 2012, with the first devices using the OS planned to reach the market in mid 2012.[64][65]
Windows 8 from Microsoft (closed source, proprietary)
Microsoft announced that Windows 8 will support tablet devices as well as PCs.
Windows RT from Microsoft (closed source, proprietary)
Microsoft announced Windows RT. an OS design for only tablets and can only run on arm. This version also resembles windows 8. Windows RT cannot run x86 programs. Apps can be only downloaded from the windows store. This version also has Microsoft office 2013 preinstalled on every Windows RT device.
