Well, after the first time do view.isUserInteractionEnabled = false and in the method viewWillDisappear set a flag to true. This method is invoked when a person leaves the controller in which is view. Save somewhere this flag, or make it global for all controllers. Well, in the following entry, checking this flag will return isUserInteractionEnabled. If he did not go anywhere, then moisture above won't give click.
