No. But try the "Snapchat App" Solution.
User has to touch and hold the screen to see you view controller. If he trys to make a screenshot ios invoke touchesCancelled.
If this is invoked you have to blank you screen or somethinge else to anomynus your view.
What do you plan to do if they point a camera at the screen?
