cannot initialize a parameter of type UIRemote NotificationType with an rvalue of type int

Question

When I use [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)]; to register remote push notificatioin, an error occurs saying cannot initialize a parameter of type 'UIRemoteNotificationType' with an rvalue of type 'int', does anybody know why? thank you.

My project's environment: Xcode 4.2 + iOS 5.

Answer 1

You should cast it explicitly to UIRemoteNotificationType

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationType)(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
