Apple iOS 7 Officially Released with Flat and Simple Interface

Apple's annual Worldwide Developers Conference (WWDC) was held at the Moscone West Center in San Francisco. At the conference, iOS 7 was officially announced. But the next generation Apple iPhone was not shown. 

As the rumors before the conference, iOS 7 operating interface includes "Flat" and "Simple" design. It has a fresh look and a new, birghter color palette, which radically changes the feel of the interface. 

Moreover, the new iOS7 can sense the movement of the screen. If there is any changes of the holding direction of your phone, the user interface can respone to your movement for the phone and shift shadows, which creates a 3D look.
