Hi,

when you tap the tutorial really fast the app crashes. This happens because the cleanup method is called before all animations did finish. I fixed this issue by implementing the Quartzcore framework and add the line [UIView setAnimationDelegate:self] in the init method. Then I added the two methods

(void) animationDidStart:(CAAnimation *)anim
(void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag

This allows me to set a BOOL isAnimting whenever the animation starts or stops.

Then I changed the swipeOrStopTapInWindow method like this:

-(void)swipeOrTapInWindow:(UISwipeGestureRecognizer*)sender {

warning animation should stop before running this line

if(!self.isAnimating)
    [self animateToNextTutorialStepOrStop];

}

Maybe you can try this and add this to your code.

Kind regards
