title: Read camera permission for iOS in Xamarin
body: <p>I have an iOS app developed in Xamarin. When the app does not have permission to access the microphone, if the user tries to access the microphone from the app, I check the settings using <code>AVAudioSession.SharedInstance().RequestRecordPermission (delegate(bool granted))</code> and display a message.</p>
  
  <p>Now I need to do the same if the app does not have permission to access the camera. I need to check if permission is granted for camera and display a message accordingly. How can I do this?</p>
