How to customise the Camera screen frame?

问题

I want to lauch camera with customised frame so that I should be able to show UIsearchBar in the same View and on touching the UISearchBar I need to close the camera, but the UIsearchBar should be visible. So I want to stop the camera to take the full iPhone screen as a frame. So I want to know how to customise the Camera Screen?

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

Here is a simple tutorial on how to take a picture with AVFoundation: http://www.musicalgeometry.com/?p=1297
