screenshot - Prevent screen capture in an iOS app

Question

I need to prevent screen capture by users of my app, for security reasons. The contents I display are confidential and should not be copied onto the device. I saw one answer on Stack Overflow, but for Android.

Is it possible somehow in iOS to prevent screen capture?

While capturing the screenshot into the gallery by the click of few buttons is a very useful feature for the user, there is a limited requirement to prevent it too. Any pointers?

Answer 1

There's no way to prevent taking screenshots entirely. You can do what Snapchat does, which is by requiring the user to be touching the screen to view whatever information you're displaying. This is because the system screenshot event interrupts touches. It's not a perfect method and you can't prevent users from taking screenshots 100% of the time.
