Question

I want to implement this function on my apps but i cant seem to figure out how to use this line of codes.

- (void)applicationWillResignActive:(UIApplication *)application {
 //our app is going to loose focus since there is an incoming call
 [self pauseGame];
}

- (void)applicationDidBecomeActive:(UIApplication *)application{
 //the user declined the call and is returning to our app
 [self resumeGame];
}

I’ve read that this must be placed in appdelegates but i cant seem to figure out how could i call my pause action when the game is currently in the viewcontroller.

Thank you.

Instead of sending the messages to self (which is the app delegate), you would send them to your view controller.

For example, if your app delegate had a property for your main game view controller named “gameViewController” (where the methods to pause and resume were implemented):

- (void)applicationWillResignActive:(UIApplication *)application {
    // our app is going to loose focus since there is an incoming call
    [self.gameViewController pauseGame];
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    // the user declined the call and is returning to our app
    [self.gameViewController resumeGame];
}
