title: iPhone Camera Iris / Shutter stuck in closed position
body: <p>As the title states the app that I am developing has an issue that is caused only when the app is relaunched after entering the background.</p>
  
  <p>The camera iris or shutter gets stuck in the closed position. The funny thing is you can still take a picture but you cannot see the preview. Once the picture is taken, it is shown correctly in the view.</p>
  
  <p>This issue does not happen when the app is launched if the app is completely closed. I can take pictures, add effects and so on, every time the camera is opened it works correctly.</p>
  
  <p>Here are the exact steps to reproduce the issue:</p>
  
  <p>1) I open the app, everything works fine.</p>
  
  <p>2) The app enters the background either by pressing the home button or incoming call.</p>
  
  <p>3) When the app enters the foreground / reopened and the camera is accessed the shutter screen is shown and remains closed in the stuck position.</p>
  
  <p>4) The only way to fix it is to dismiss the modal view camera controller and press the camera button again.</p>
  
  <p>I have done some research to find an answer and have come up with nothing. There are no memory leaks and I have checked the memory allocations in instruments and there is nothing unusual.</p>
  
  <p>Hopefully someone has a solution, I appreciate the help.</p>
  
  <p>Thank you in advance.</p>
