问题
After a lot of searching on here I finally found a way for Game Center to display in SpriteKit but now I can't get the leaderboardViewControllerDidFinish method to call. I use this code in a different app and it works fine but for some reason with the code being modified for SpriteKit its just not working. Thank you in advance!
Here is a sample of my code:
- (void)showGameCenterButtonPressed:(id)sender {
{
if ([GKLocalPlayer localPlayer].authenticated == NO) {
UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"You must enable Game Center!"
message:@"Sign in through the Game Center app to enable all features"
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[message show];
} else {
GKGameCenterViewController *leaderboardViewController = [[GKGameCenterViewController alloc] init];
if (leaderboardViewController != NULL)
{
UIViewController *vc = self.view.window.rootViewController;
[vc presentViewController: leaderboardViewController animated: YES completion:nil];
}
}
} }
- (void)leaderboardViewControllerDidFinish:(GKGameCenterViewController *)viewController {
NSLog(@"in leaderboardControllerDidFinish");
UIViewController *vc = self.view.window.rootViewController;
[vc dismissViewControllerAnimated:YES completion:nil];
}

To answer my own question... I just took the code straight from Apple
- (void)showGameCenterButtonPressed:(id)sender {
{
if ([GKLocalPlayer localPlayer].authenticated == NO) {
UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"You must enable Game Center!"
message:@"Sign in through the Game Center app to enable all features"
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[message show];
} else {
GKGameCenterViewController *gameCenterController = [[GKGameCenterViewController alloc] init];
if (gameCenterController != nil)
{
gameCenterController.gameCenterDelegate = self;
gameCenterController.viewState = GKGameCenterViewControllerStateLeaderboards;
UIViewController *vc = self.view.window.rootViewController;
[vc presentViewController: gameCenterController animated: YES completion:nil];
}
}
}
}
- (void)gameCenterViewControllerDidFinish:(GKGameCenterViewController*)gameCenterViewController {
UIViewController *vc = self.view.window.rootViewController;
[vc dismissViewControllerAnimated:YES completion:nil];
}
