iOS is Apple's mobile operating system used
to run the popular iPhone, iPad and iPod Touch devices. Formerly known as the
iPhone OS, there are over 900,000 iOS applications available for download in
the Apple app store, the most popular app store of any mobile device. iOS
utilizes a multi-touch interface where simple gestures are used to operate the
device, like swiping your finger across the screen to move to the next page or
pinching your fingers to zoom out.
The new version iOS 8 includes over 4,000 new APIs that let you add amazing new features and capabilities to your apps. Deeper integration with iOS means you can extend the reach of your app content and functionality. And with bold new technologies for game development, you can create even more incredible, responsive, and immersive gaming experiences.
