问题
I want to add two extra buttons to my UIImagePickerController. I saw that done in an app: camwow but I couldn't find the documentation to do that. I have a view overlay over the UIImagePickerControllerSourceTypeCamera but at the moment touches on the buttons from the view overlay propagate to the camera controller which focuses.

I have had the same problem. Read these articles http://blog.airsource.co.uk/index.php/2008/11/11/views-of-uiimagepickercontroller/ and http://www.codza.com/custom-uiimagepickercontroller-camera-view
That helped me a lot
