title: Prevent screen capture in an iOS app
body: <p>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 <a href="https://stackoverflow.com/questions/6764568/prevent-screen-capture-in-android-apps">one answer on Stack Overflow, but for Android</a>.</p>
  
  <p>Is it possible somehow in iOS to prevent screen capture? </p>
  
  <p>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?</p>
