I am creating a window-based application in XCode 4 (I am using window-based because I like how the universal apps are organized), but I am having trouble with the UIImagePickerControllerSourceTypeSavedPhotosAlbum. I tried stripping down the code as much as possible to avoid any external errors, but I want to have two views:
the parent view: threeeyesmain.h / m / xib
the sub view: threeeyescamera.h / m / xib
I will post the code I have so far below.
The main issue is, when I push the button to take a picture with the camera, it works and I can see the camera controls, and I can even take a picture with no problem. However, whatever objects that are in the parent view are covering the camera screen. (ie if I am pointing my camera over a picture of a flower, I can see the flower on the screen, but there are buttons and imageviews from the parent view overlayed on it. I hope that makes sense).
(Side note: The funny thing is, when I tried this before using a view based application, it seemed to work, but now using virtually the same code in a windows based application, I get these problems.)
Maybe I am just missing something really obvious. Any help would greatly be appreciated. Thanks!
