In my app, i have added 1 UICollectionview and use UIImagePickerController to take a photo and then upload to server, collectionview is used to display all photos. But when I click on Camera button in my app to open Camera, I received the warning Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates. in console log. Sometime the camera screen is black screen. I tried searching but i cannot solve this issue. Can you please help me to solve this issue? Thanks in advance.

2@NTNT I'm encountering this error as well. Whenever it occurs, the image preview that pops up once a new picture has been taken is completely black. However, the "Re-Take" and "Use Photo" buttons at the bottom of the screen still appear and function properly. Are you witnessing this same behavior? – Barry Beerman Sep 25 '14 at 15:27
