Just interested, if anyone has any sample code, using the UIImagePicker for a cameraview in fullscreen with landscape/portrait rotations.

Instead of 

[self presentModalViewController:imagePicker animated:NO];

I’m adding the imagepicker.view as a sub View like so:

[cameraView addSubview: imagePicker.view];

The problem is, when this happens, the frame of the imagePicker.view is being added with a 90 degrees rotation. Which would be fine to perform an affine Translation, except doing so changes the rotation of the actual Camera feed.

Doing something like, works fine, 

[imagePicker.view setFrame: CGRectMake(0, 0, 480, 320)];

until the user rotates.

I can listen for the rotate notification with this:

- (void) didRotate:(NSNotification *)notification

But applying a Affine Translation, is ruining the camera overlay and it’s subviews.

    The outcome was that using the UIImagePicker for the modal camera popup isn’t appropriate for more than basic AVCamera usage. I still used it for picking existing photos, but ended up using the sample code

    My main VC header keeps:

    UIImagePickerController *_imagePicker;
AVCameraView *avCameraView;

    AVCameraView retains:

    @property (retain) CaptureSessionManager *captureManager;

    Which is used to take photos as well as swap between the front/back camera if the device is a 4+
