[Fast hint] Simple animation with CoreAnimation

Let's create a simple animation to flip UIImageView and change your image First Step create a UIImageView object

@interface MyClass : UIViewController{
     UIImageView *myImageVIew;
}
@end

set a default image

- (void)viewDidLoad {
       [myImageView setImage:[UIImage imageNamed:@"image1.png"]];
}

Now let's to create the animation

-(void)flipAndChangeImage{
[UIView transitionWithView:myImageView duration:1 options:UIViewAnimationOptionTransitionFlipFromLeft 
	animations:^{  
              [myImageView setImage:[UIImage imageNamed:@"image2.png"]];
        }
	completion:NULL]; 
}

Now we call function flipAndChangeImage in a action for example

-(IBAction)callAnimation{
    [self flipAndChangeImage];
}

We have done a little animation We can use others effects for example

    UIViewAnimationOptionTransitionFlipFromLeft
    UIViewAnimationOptionTransitionFlipFromRight
    UIViewAnimationOptionTransitionCurlUp
    UIViewAnimationOptionTransitionCurlDown
