Question

I can’t seem to re edit this object in my ios User Defaults. Here is my code…

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults setObject:nil forKey:@"savedScoreCards2"];

Before I did this I set the key savedScoreCards to a huge 3-d dictionary, and now when I try to over write it or even set the key to nil that huge 3-d dictionary that I set up a while ago is still there. I can’t seem to over write/ replace it will nothing (nil), or another huge 3-d dictionary. Any ideas?

UPDATE:

  + (void)saveCurrentScoreCard 
  {
    //save score card
    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    NSMutableDictionary *savedScoreCards = [[NSMutableDictionary alloc] init];
    [userDefaults setObject:nil forKey:@"savedScoreCards2"];//reset at beginning

    NSMutableArray *golferOneScoresu = [userDefaults arrayForKey:@"golferOneScoresArray"];
    NSMutableArray *golferTwoScoresu = [userDefaults arrayForKey:@"golferTwoScoresArray"];
    NSMutableDictionary *golferIconsu = [userDefaults objectForKey:@"golferIconsFirstScene"];
    NSMutableArray *golferThreeScoresu = [userDefaults arrayForKey:@"golferThreeScoresArray"];
    NSMutableArray *golferFourScoresu = [userDefaults arrayForKey:@"golferFourScoresArray"];
    NSMutableDictionary *golferIcons2u = [userDefaults objectForKey:@"golferIcons"];
    NSMutableArray *golferNamesu = [userDefaults objectForKey:@"golferNames"];

    NSMutableArray *golferNames = [[NSMutableArray alloc] initWithArray:golferNamesu copyItems:YES];
    NSMutableDictionary *golferIconsSceneOne = [[NSMutableDictionary alloc]initWithDictionary:golferIconsu];
    NSMutableDictionary *golferIcons = [[NSMutableDictionary alloc]initWithDictionary:golferIcons2u];
    NSMutableArray *golferFourScores = [[NSMutableArray alloc] initWithArray:golferFourScoresu copyItems:YES];
    NSMutableArray *golferThreeScores = [[NSMutableArray alloc] initWithArray:golferThreeScoresu copyItems:YES];
    NSMutableArray *golferOneScores = [[NSMutableArray alloc] initWithArray:golferOneScoresu copyItems:YES];
    NSMutableArray *golferTwoScores = [[NSMutableArray alloc] initWithArray:golferTwoScoresu copyItems:YES];

    NSMutableDictionary *currentScoreCard = [[NSMutableDictionary alloc] init];

    [currentScoreCard setObject:golferNames forKey:@"golferNames"];
    [currentScoreCard setObject:golferIconsSceneOne forKey:@"golferIconsFirstScene"];
    [currentScoreCard setObject:golferIcons forKey:@"golferIcons"];
    [currentScoreCard setObject:golferOneScores forKey:@"golferOneScoresArray"];
    [currentScoreCard setObject:golferTwoScores forKey:@"golferTwoScoresArray"];
    [currentScoreCard setObject:golferThreeScores forKey:@"golferThreeScoresArray"];
    [currentScoreCard setObject:golferFourScores forKey:@"golferFourScoresArray"];

    [savedScoreCards setObject:currentScoreCard forKey:@"1"];

    NSLog([golferIconsSceneOne objectForKey:@"30101"]);

    [userDefaults setObject:savedScoreCards forKey:@"savedScoreCards2"];
    [userDefaults synchronize];
    NSLog(@"SAVED SCORE CARD");
}

Use [userDefaults removeObjectForKey:@"savedScoreCards2"] if you’re just trying to remove a stored value.
Also call [userDefaults synchronize]; to “flush” your changes immediately. I think the [userDefaults synchronize] is probably what you’re missing.
