CCLabelTTF SetString not Updating

Question

I'm using a CCLabelTTF to show the score of the player on the screen. However, when I'm calling setString to update the score label, it doesn't update (so it always stays at 0).

Here's my code :

In Player.m, I initiate a new PlayerHUD object:

- (id) init{
    if (self = [super init]){
        playerHUD = [[PlayerHUD alloc] loadPlayerInterface];
        [self addChild:playerHUD z:UPLAYER_Z];
    }
    return self;
}

In PlayerHUD.m, I initiate the Score Label :

- (id) loadPlayerInterface{
    if (self = [super init]){
        score = 0;
        //Score Label
        lblScore = [CCLabelTTF labelWithString:[NSString stringWithFormat:@"%d", score] fontName:@"pixel" fontSize:24];
        [self addChild:lblScore z:1000];
    }
    return self;
}

Still in PlayerHUD.m, here's my update function :

- (void) updateScore:(NSInteger)_newscore{
    score = _newscore;
    [lblScore setString:[NSString stringWithFormat:@"%d", score]];
}

And, in Player.m, I call the update function here :

- (void) addScore{
    int scoreToAdd = 50

    score += scoreToAdd;

    NSLog(@"Score:%d", score);
    [playerHUD updateScore:score];
}

put breakpoints into addScore and updateScore: methods and check if they are called — Morion
@Morion Weird enough, my updateScore: method never get called (I tried with a breakpoint like you said!) Do you have an idea? — RaphBlanchet
@InderKumarRathore My log is alright, it's updating well (Score:50, Score:100, etc) And if by ARC you mean property and synthesize, no, I'm not using that, should I? (I don't really know what means ARC) — RaphBlanchet

I managed to solve this issue using the code below (set string to an empty string then reSet it to your string)

[label setString:@""];
[label setString:yourString];
