PhotoPicker demonstrates choosing images from the photo library, take a picture with the camera, and customizing the camera view. This is done by using UIImagePickerController. The chosen image or camera photo is displayed in a UIImageView.
To customize the camera's interface, this sample shows how to use an overlay view. With this overlay view it gives you the ability to customize the UI as you take a picture.
Among the custom features of the camera is to take a single picture, timed picture, or repeated pictures like a camera with a fast shutter speed. Timed and shutter speed camera shots are done using the NSTimer class.
