In-Depth Information
Then you want to add a new application, even if it doesn't exist yet. For most fields
that iTunes Connect asks you to fill out, you can enter bogus information. There are
only two settings that you have to get right. The first is, obviously, to enable Game
Center when iTunes Connect asks you whether the new application should support
Game Center.
The other is to enter a Bundle ID (also referred to as Bundle Identifier) that matches
the one used in the Xcode project. Because you don't have an Xcode project yet,
you're free to choose any Bundle ID you want. Apple recommends using reverse do-
main names for Bundle IDs with the app's name appended at the end. The catch is that
the Bundle ID needs to be unique across all App Store apps, and there are tens of thou-
sands of them.
For the topic's example, I chose com.learn-cocos2d to be the app's Bundle ID.
Because this Bundle ID is now taken by me, you'll have to use your own Bundle ID. If
you want, you can simply suffix it with a string of your choosing or choose an entirely
new string.
Note Remember to use your own Bundle ID whenever I refer to the
com.learn-cocos2d Bundle ID.
For a detailed description of how to create a new app and how to set up Game Center
for an app on iTunes Connect, refer to Apple's iTunes Connect Developer Guide: ht-
nect_DeveloperGuide.pdf .
Specifically, the “Game Center” section explains in great detail how to manage the
Game Center features on iTunes Connect.
Setting Up Leaderboards and Achievements
For the most part, after enabling Game Center for an app, what you'll be doing on
iTunes Connect is setting up one or more leaderboards to hold your players' scores or
times, and setting up a number of achievements that players can unlock while playing
your game.
