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?
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.
