The cleanest I could do for this at the moment is to just put all the changes in label to LabelView and calling them in the controller.

CONTROLLER

-(void)endGame
{
    [self resetGame];
    BOOL isNewHighScoreAchieved = [self didPlayerAchieveHighScore];
    [self showGameOverScreenDidAchieveHighScore:isNewHighScoreAchieved];
}
-(BOOL)didPlayerAchieveHighScore
{
    if(_currentScore > _highScore)
        return YES;
    else
        return  NO;
}

-(void)showGameOverScreenDidAchieveHighScore:(BOOL)highScoreIsAchieved
{
    if(highScoreIsAchieved) {
        self.highScore = _currentScore;
        [self writeFileToSandBox];
        [self.labelView showGameOverWithNewHighScore:_currentScore];
    }
    else
        [self.labelView showGameOverWithScore:_currentScore
                                withHighScore:_highScore];
   
}

and then in the label view

-(void)showGameOverWithScore:(int)score withHighScore:(int)highscore
{
    NSString *string = [NSString stringWithFormat:@"%@%i%@%i",GAME_OVER_LABEL,score,GAME_OVER_LABEL_H,highscore];
    self.gameOverLabel.text = string;
}
-(void)showGameOverWithNewHighScore:(int)score
{
    NSString *string = [NSString stringWithFormat:@"%@%i%@",GAME_OVER_LABEL,score,GAME_OVER_LABEL_N];
    self.gameOverLabel.text = string;
}


If you have any other suggestion I'm all ears. Thank you.
