Game Center Does not recognize my game?

[codyspraker]

I have a fairly simple game which i am trying to incorporate game center into, i have seen videos and added the necessary code. However when i get the sign in box and enter my username and password it says that the game is not recognized by game center. When i try to submit a score the game crashes with a sigABRT error. I am sent to a blank leaderboard in game center when i try to access the leaderboard.


-(void) sendScore
{
GKScore *scoreReporter = [[[GKScore alloc] initWithCategory:@"1234567890"] autorelease];
scoreReporter.value = firstStoredScore;
[scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
if(error != nil)
{
NSLog(@"submit score Failed");
}
else
{
NSLog(@"submit score was successful!");
}
}];

}
-(void) showLeader
{
GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
if(leaderboardController != nil)
{

leaderboardController.leaderboardDelegate = self;
[self presentModalViewController:leaderboardController animated:YES];

}
}


-(void) leaderboardViewControllerDidFinish:(GKLeaderboardV iewController *)viewController
{

[self dismissModalViewControllerAnimated:YES];


}


- (void)viewDidLoad {
[super viewDidLoad];

[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) {
if(error == nil)
{
NSLog(@"Authentication Successful!");

}

else
{
NSLog(@"Authentication failed");

}
}];

defaults = [NSUserDefaults standardUserDefaults];
[self update];

}
-(IBAction) submit: (id) sender
{
[self sendScore];
}

-(IBAction) showLeader: (id) sender
{
[self showLeader];
}
