Cannot Close Game Center Leaderboards Page - ios

Question

I can load up leaderboards with no problem. But I can't get it to close when the "Done" button is clicked.
How I'm opening it:
- (IBAction)leaderboardsClicked:(id)sender{
if ([GKLocalPlayer localPlayer].isAuthenticated) {
GKGameCenterViewController *leaderboardController = [[GKGameCenterViewController alloc] init];
[self presentViewController:leaderboardController animated:YES completion:NULL];
}else{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle: #"Error"
message: #"You must be logged into Game Center to view the leaderboards. Open Game Center?"
delegate: self
cancelButtonTitle:#"No"
otherButtonTitles:#"Yes",nil];
[alert show];
}
}
How I'm closing it:
- (void)gameCenterViewControllerDidFinish:(GKGameCenterViewController *)gameCenterViewController{
NSLog(#"test");
[self dismissViewControllerAnimated:YES completion:nil];
}
EDIT:
The method isn't running at all; so "test" doesn't even get printed.
And I added <GKGameCenterControllerDelegate> to my ViewController's protocol.

Answer 1

Try this instead:
- (IBAction)leaderboardsClicked:(id)sender{
if ([GKLocalPlayer localPlayer].isAuthenticated) {
GKGameCenterViewController *leaderboardController = [[GKGameCenterViewController alloc] init];
leaderboardController.gameCenterDelegate = self;
gameCenterController.viewState = GKGameCenterViewControllerStateLeaderboards;
[self presentViewController:leaderboardController animated:YES completion:NULL];
}else{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle: #"Error"
message: #"You must be logged into Game Center to view the leaderboards. Open Game Center?"
delegate: self
cancelButtonTitle:#"No"
otherButtonTitles:#"Yes",nil];
[alert show];
}
}
And:
- (void) gameCenterViewControllerDidFinish:(GKGameCenterViewController*) gameCenterViewController {
[self dismissViewControllerAnimated:YES completion:nil];
}
