How to get authenticated player's high score form leaderboard ( Game Center )

Question

I need to retrieve authenticated player's submited score from Game Center. I use this code to get the score, but it just gets the top score (best score of the leaderboard not the specified player's score). How can I retrieve the authenticated player's score?

- (void) retrievePlayersScore {
    GKLeaderboard *leaderboardRequest = [[GKLeaderboard alloc] init]; 
    if (leaderboardRequest != nil) {
        leaderboardRequest.playerScope = GKLeaderboardPlayerScopeGlobal; 
        leaderboardRequest.timeScope = GKLeaderboardTimeScopeAllTime; 
        leaderboardRequest.range = NSMakeRange(1,1);
        [leaderboardRequest loadScoresWithCompletionHandler: ^(NSArray *scores, NSError *error) {
            if (error != nil) {
                // handle the error. if (scores != nil)
            }
            if (scores != nil){
                // process the score information.
                CCLOG(@"My Score: %d", ((GKScore*)[scores objectAtIndex:0]).value);
            } 
        }];
    }
}

You can use the following code:

GKLeaderboard *leaderboardRequest = [[GKLeaderboard alloc] init];

leaderboardRequest.identifier = _leaderboardIdentifier;

if (leaderboardRequest != nil) {
    [leaderboardRequest loadScoresWithCompletionHandler:^(NSArray *scores, NSError *error){
        if (error != nil) {
            //Handle error
        }
        else{
            [delegate onLocalPlayerScoreReceived:leaderboardRequest.localPlayerScore];
        }
    }];
}
