Answer 1

I downloaded your project and it seems the translation you're making for self.view. So the actionHiddenButton is not in the frame.Its better to have the controls you want to animate in the separate view.
If you want to see the problem, after your view get transformed set clipsToBounds to YES. Like

    self.view.transform = translation;
    self.view.clipsToBounds = YES;
