Registering the iOS Client

In Sybase Control Center configure push notification:
1. Select Application > Applications > select the application > Properties.
2. In the Properties window, select Push Configuration > Add.
3. In the Push Configurations window, enter the Name, Domain, Type (APNS), Server (APNS Server), Port, Feedback server, and Feedback port.
4. Browse and upload an Apple Push Notification Service p12 certificate, and enter the certificate password.
5. Click OK to save.

Enable push notifications in the application itself:

Call the registerForRemoteNotificationTypes: method.
In your delegate, implement the application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken: and application:(UIApplication *)app didRegisterReceiveRemoteNotification: methods to receive the device token and notifications.

Create an application connection, and include the ApnsDeviceToken, and DeviceType properties.
