save and load data

in my game i use NSUserDefults to save the user highscore. in the first time i finushed the game my highscore is set to the game score, but every time after that the score in the game is automatically set as the highscore. the weirdness here is that id my game score is 0 then my highscore is stay as the biggest score, but if in the end of some game my score is 100 is sets as highscore but a game after that if my score is 50 my highscore is sets as 50(although the score was lower then my highscore). here is my viewdidload code:

    highScore = [[[NSUserDefaults standardUserDefaults] objectForKey:@"HighScore"] intValue ];
highScoreLabel.text = [NSString stringWithFormat:@"%d",highScore];

here is my checkIfHighscore code:

-(void)checkIfHighScore
{
    if(gameOverScore > highScore)
    {
        highScore = gameOverScore;
        [[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithInt:highScore] forKey:@"HighScore"];
        [[NSUserDefaults standardUserDefaults] synchronize];

    }
    highScoreLabel.text = [NSString stringWithFormat:@"%d", highScore];
}

what is the problem?

Your highScore loaded form NSUserDefaults is going to be an Object of type id, you should cast it to NSNumber, secondly in your checkIfHighScore method, you should compare highScore.intValue to gameOverScore, and then:

[[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithInt:gameOverScore] forKey:@"HighScore"];

Notice how you are mixing number objects and scalar types (int), you can't use the < and > operators, or even == between an Object and a scalar variable.
