I-PHONE , I-PAD DEVELOPMENT


iOS is Apple's proprietary mobile operating system (OS) for its handheld devices, such as the iPhone, iPad and iPod Touch.

iOS is the world’s most advanced mobile operating system, continually redefining what people can do with a mobile device. Together, the iOS SDK and Xcode IDE make it easy for developers to create revolutionary mobile apps.

iOS/iPhone OS is a mobile operating system developed by Apple Inc. and distributed exclusively for Apple hardware.

Derived from core OS X technologies, the amazing user experience of iOS has been streamlined to take maximum advantage of iPhone, iPad, 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.

The user interface of iOS is based on the concept of direct manipulation, using multi-touch gestures. Interface control elements consist of sliders, switches, and buttons. Interaction with the OS includes gestures such as swipe, tap, pinch, and reverse pinch, all of which have specific definitions within the context of the iOS operating system and its multi-touch interface. Internal accelerometers are used by some applications to respond to shaking the device (one common result is the undo command) or rotating it in three dimensions (one common result is switching from portrait to landscape mode).

Major versions of iOS are released annually. The current release, iOS 8.1, was released on October 20, 2014. In iOS, there are four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer. The current version of the operating system (iOS 8.0), dedicates 1.3 - 1.5GB of the device's flash memory for the system partition, using roughly 800 MB of that partition (varying by model) for iOS itself. It runs on the iPhone 4S and later, iPad 2 and later, all models of the iPad Mini, and the 5th-generation iPod Touch.

Designed for use with Apple’s multi-touch devices, iOS supports input through direct manipulation. The system responds to various user gestures, such as pinching, tapping and swiping.
