Question

I tried animating a sequence of UIViews from a mutable array to simulate this animation

for(int k = 0; k< [imageViewCarrier count] ; k++){
    UIView *transformingView = [imageViewCarrier objectAtIndex:k];
    [UIView animateWithDuration:30.0 animations:^{
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:30.0];
        [UIView setAnimationDelegate:self];
        [UIView transitionFromView:transformingView toView:splicedImageView duration:3 options:UIViewAnimationOptionTransitionFlipFromLeft completion:NULL];
        [UIView commitAnimations];

    }completion:^(BOOL finished){
        NSLog(@"Transition done");
    }];

}

The animation seems to be too fast. Any suggestions on this. Did search some documentation but couldn’t figure it out. Some help would be greatly appreciated!

Hm, I think you might be doing it the wrong way. If memory serves me, when using [UIView animinateWithDuration:animiations:completion:], you shouldn’t call [UIView beginAnimations:nil context:NULL]; and [UIView commitAnimations]; or setAnimationDelegate: or setAnimationDuration: for that matter, since they are the old way of animating views that you had to use before the block-based methods were introduced.

I’d try leaving those out and see what happens. Also, note that the duration parameter is in seconds, so 30.0 seems a bit too long.

And just a style note: the “proper” Objective-C way to iterate through a collection is as follows:

for(UIView* view in imageViewCarrier){
   [view doSomething];
}
