You basically have two options. The easiest one is to use the cameraOverlayView property of the UIImagePickerController. This allows you to display a view on top of the camera:

If you need something more elaborate you can use the AVFoundation framework. In short, it will allow you to display the camera stream anywhere you want in a view: http://developer.apple.com/library/IOS/#documentation/AudioVideo/Conceptual/AVFoundationPG/Articles/04_MediaCapture.html#//apple_ref/doc/uid/TP40010188-CH5-SW2
