How do I turn off autosnap of UIImagePickerViewController?

[lukeirvin]

I am working on a custom overlay for UIImagePickerViewController.

Currently when I launch the camera function of my app the overlay appears nicely but the camera is wanting to do an auto snap shot.

How do I turn this off so I can view what I want and then take a picture via a UIBarButtonItem?

Here is the code I am using:

UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.showsCameraControls = NO;
picker.cameraOverlayView = cameraView;

Thanks!

Maybe a better approach would be a custom implementation instead of changing and messing with the picker. Check out the AVCam sample code from the docs, you can do almost anything that way.
