The last chapter that I covered before the completion of this book was on using the camera. One of the IPhone's main limitations is that you are generally restricted to your own application's "sandbox" meaning that you can not access things outside of your own data. The camera is an exception to this. An application can not only access your camera, but can also access your library. In a simple application that I made through following the tutorial, you can either take a picture with your camera, or choose a picture from your library and it will display it on the screen. It is a very simple application that allows you to see how this works.
