I was trying to implement an event listener in a turn based game so a player can receive when his turn is active or when he is invited by a friend. GKTurnBasedEventHandler is deprecated in IOS 7 and i read in the documentation that i should use GKLocalPlayerListener; but that's the extend of it. Is there someone who used it already, because there is no info anywhere.
This is what i tried before, and it does not work.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
[localPlayer authenticateWithCompletionHandler:^(NSError *error)
{
if (localPlayer.isAuthenticated)
{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
[localPlayer registerListener:self];
}
}];
return YES;
}
-(void)handleInviteFromGameCenter:(NSArray *)playersToInvite
{
NSLog(@"test");
}
- (void)player:(GKPlayer *)player receivedTurnEventForMatch:(GKTurnBasedMatch *)match didBecomeActive:(BOOL)didBecomeActive
{
NSLog(@"test");
}
Here is some code that I use in order to register GKLocalPlayerListener
The documentation states that you should only register for an GKLocalPlayerEventListener once so you could improve this code by checking if you've already registered.
Note that
authenticateWithCompletionHandler
is deprecated in iOS 6 and they recommend setting the authenticateHandler property like I did above.I believe you were there. Just this time do a couple of things. Make sure you dont add multiple listeners also before you add a listener, just incase unregister all listeners.
I made sure I only did this once in my whole project, but I get the local player multiple times.
I might be a little late, but hopefully it will help someone out there...
This is what I do. According to Apple's documentation I create [my] own method that displays an authentication view when appropriate for [my] app.
This code is inside a singleton helper class, it might be simplified if you have it on your own class.
