15.2. Creating peer-to-peer applications using the peer picker

The peer picker gives you a simple way to connect two devices over Bluetooth or wireless. It involves displaying Apple’s built-in Peer Picker view and implementing the delegate methods. This view is easy to use but is somewhat limited. First, it allows a connection only between two peers. You can never have more than two users playing the same game at once. Second, it can’t be customized. Although the view looks nice, it may not always fit into the look and feel of your application.

If you find yourself in a situation where you need to connect more than two peers at a time, you must create your own custom peer picker. Because we’ll be focusing on using Apple’s built-in peer picker, you should refer to the developer documentation titled “Game Kit Programming Guide” if you want more information about creating one.
