UIView animation ignores duration

Question

I'm trying to perform an animation from within a UIView subclass, on one of its subviews. The animation duration ignores any value I try to set it to, and just performs on a permanent duration of ~2 secs. The `finished` flag returns with True. ``` [UIView animateWithDuration:0.5f animations:^{ img.frame = newFrame; } completion:^(BOOL finished) { NSLog(@"result: %d", finished); }]; ``` When I'm using the old way, it works fine: ``` [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:0.5f]; img.frame = newIconRectFinal; [UIView commitAnimations]; ``` What could be the problem?

Accepted Answer

You probably have the animation encapsulated inside another animate and its duration is being used for both of the animations.
