Flip Viewby Wu xueying

CGContextRef context = UIGraphicsGetCurrentContext (); [UIView beginAnimations: nil context: context]; [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView: self. view cache: YES]; [UIView setAnimationCurve: UIViewAnimationCurveEaseInOut]; [UIView setAnimationDuration: 1.0]; [self. view exchangeSubviewAtIndex: 0 withSubviewAtIndex: 1]; [UIView commitAnimations];
