How to block a screen shot in an iOS application

Question

I want to build a application in which I want to block screen shot by user like in Netflix application, it should return a black screen shot as in Netflix. Right now I am unable to get anything regarding this.

I don't know how Netflix is handling this?

Is there any way to detect captured image in the block and we can make it obscured?

Answer 1

Netflix (and other providers) use "FairPlay Streaming" which is what prevents capture of the video content - link: https://developer.apple.com/streaming/fps/

Note that you can do a screen-shot of the Netflix UI (menus and such), just not the streaming content.

If you do a little searching, you will find plenty of discussion explaining that you cannot block screen captures in iOS.
