Question

I am creating some animation on my application and the code below zooms out an object till it disappears. I can’t figure out how to make the object to disappear and keep that way, ie. how to make the animation stay put after it finishes. Any gotchas on that? Cheers!

        CABasicAnimation* zoomOut = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
        zoomOut.duration = 1;
        zoomOut.toValue = [NSNumber numberWithFloat:0];
        [draggedObject addAnimation:zoomOut forKey:nil];

Ok so this happens because the animation doesn’t actually change the underlying property, which is why it jumps back after the animation is complete.

Try adding this line before the line starting the animation –
zoomOut.removedOnCompletion = NO;
