How to flip an individual UIView (without flipping the parent view)

by

this code may helps you:

put the two views you want to flip inside an unnamed view with the same size
and link the IBOutlet UIView *newView,*oldView; to the views and put the new view on top

bool a = NO;

@implementation ViewController

- (IBAction)flip:(id)sender 
{
    if (a == NO) {
        [UIView transitionFromView:oldView toView:newView  
                  duration:1.0 
                  options:UIViewAnimationOptionTransitionFlipFromLeft 
                  completion:NULL];
        a = YES; // a = !a;
    }
    else {
        [UIView transitionFromView:newView toView:oldView  
                  duration:1.0 
                  options:UIViewAnimationOptionTransitionFlipFromLeft 
                  completion:NULL];
        a = NO; // a = !a;
    }
}
