How to remove the shutter at the opening and closing of the iPhone Camera in app?

I have to remove the shutter at the opening of the Camera. Is there any property regarding this?

Thanks in advance.开发者_开发技巧

You can't do that using UIImagePickerController. You have to use AVFoundation framework and access the camera from lower level.

Here's some (buggy) Apple sample code AVCam to run and play with. However this code can be significantly simplified: see this.
