iOS - UIRemoteNotificationTypeBadge & Push

Question

Hello,

If my application is started and only started. I implemented application:didReceiveRemoteNotification: to receive the payload. If a message is sent to my iPhone, is this method called for every registration type, such as the following one?

1. [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeNone];
2. [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge];
3. [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeSound];
4. [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert];

I have a big doubt for solution 1...

Answer 1

The method only needs to be called once. The types argument is a bitmask of the types that you wish to register for:

[[UIApplication sharedApplication] registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound];

The code above would register for Badge and Sound remote notifications.
