issue submitting score to a leaderboard - iphone

Question

i have enabled Game Center in my itunes connect for my app.
In my game center, i have created a leaderboard named "Level 1" with its id "level1", integer.
In my game, i try to submit a score like this:
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init];
GKScore *scoreReporter = [[[GKScore alloc] initWithCategory:#"level1"] autorelease];
int64_t score1 =scr;
scoreReporter.value = score1;
[scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
if (error != nil) {
NSLog(#"Submit failed");
}
else {
NSLog(#"Score Submited");
}
}];
[pool release];
but i get a submit failed; i've created the leaderboard about 30-40 mins ago, could it not be enabled yet by apple? if else, i don't know what i'm doing wrong.
Here is my error:
Error: Error Domain=GKErrorDomain Code=6 "The requested operation
could not be completed because local player has not been
authenticated." UserInfo=0x1ed4d4a0 {NSLocalizedDescription=The
requested operation could not be completed because local player has
not been authenticated.}
btw i have internet access on my iphone and am connected on my phone to an apple account

Answer 1

Wasn't authentificated in game center, now it works!
Example from Game Center Programming Guide:
- (void) authenticateLocalPlayer
{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
[localPlayer authenticateWithCompletionHandler:^(NSError *error) {
if (localPlayer.isAuthenticated)
{
// Player was successfully authenticated.
// Perform additional tasks for the authenticated player.
}
}];
}
