There are several steps to prepare the app for push notifications. To begin, set up an App ID in the iOS Provisioning Portal. Visit the iOS Dev Center (https://developer.apple.com/devcenter/ios/index.action), log in, and choose Certificates, Identifiers & Profiles in the menu titled iOS Developer Program on the right side of the screen (you must be logged in to see this menu). Choose Identifiers from the menu on the left side of the screen. Then, click the button with a plus sign in the upper-right corner to create a new App ID, as shown in Figure 9.1.
