Can an AppDelegate run a "function" in a viewcontroller on receipt of a push notification?
The application contains three tabs, the third needs to reload its webview when the application gets a push notification.
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo {
}
yes, you need to register your viewController for the particular notification, e.g in your case when you receive a remote notification, just post a custom notification and in your viewController, register this notification/listen to this notification and perform the method you want to perform.
when you receive remoteNotification
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo {
[[NSNotificationCenter defaultCenter] postNotificationName:@"pushNotification" object:nil userInfo:userInfo];
}
in your viewController.m register the viewcontroller for this notification
- (void)viewDidLoad {
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(pushNotificationReceived) name:@"pushNotification" object:nil];
[super viewDidLoad];
}
and next implement the selector
-(void)pushNotificationReceived{
// do your stuff
}
and finally don't forget to unregister from notification in your dealloc method
-(void)dealloc {
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
