iOS, originally iPhone OS is a mobile operating system created and developed by Apple Inc. and distributed exclusively for Apple hardware. It is derived from Mac os X. It is the operating system that presently powers many of the company's mobile devices, including the iPhone, iPad, and iPod touch.Available in 34 languages worldwide

The iOS user interface 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. Internalaccelerometers 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).


Other iOS features include:


• Integrated search: It support enables simultaneous search through files, media, applications and email.

• Gesture recognition: It supports, for example, shaking the device to undo the most recent action.

• Google Maps direction services.

• Push email.

• Safari mobile browser: It is the default web browser for Apple iphones.

• Integrated camera and video.

• Integrated media player.

• Direct access to the Apple Store’s catalogue of applications, music, podcasts, television shows and movies.

• Compatibility with Apple’s cloud service, iCloud.
