Check the code and demo project for NBUAssetsGroupViewController's selectionChangedBlock then you can your own controller or use a NBUGalleryViewController which handles zoom.

Sorry, i guess my question was not clear enough. I mean to say before we take picture is there a way that we can have zoom in/out to take pictures.

Aaah. I see. That would be something like a "digital zoom" of the iPhone camera.

The camera preview is a special layer added to NBUCameraView. You could embed that view inside a UIScrollView and handle pinch to zoom as usual. Then you would need use the zoomed section rect to crop the output of takePicture:.
There are several crop methods in UIImage+NBUAdditions that you could use.
