通知はiOS9で2回表示されます

Question

私はappDelegateのapplication:didFinishLaunchingWithOptions:メソッドに次のコードを持っています。

if([application respondsToSelector:@selector(registerUserNotificationSettings:)]) { 
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil]; 

    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings]; 
} 

何か間違っていますか？
