I have a NSString that I use NSUserDefaults to store and move between multiple view controllers. The problem is, the NSString will not display in the label I am trying to show it in. Here is my code, I have no errors.

First View Controller:

 NSString *scoreString = [NSString stringWithFormat:@"%d", score];

            NSString *score = @"message";
            [[NSUserDefaults standardUserDefaults]
             setObject:scoreString forKey:@"score"];

Second view Controller:

- (void)viewDidLoad {


[[NSUserDefaults standardUserDefaults] objectForKey:@"Score"];  

    NSString *savedValue = [[NSUserDefaults standardUserDefaults]
                            stringForKe开发者_C百科y:@"score"];
    savedValue = score.text;

    [super viewDidLoad];
}

I have no idea why the string is not getting displayed, the connections are all made. Any help would be great. Thanks!


savedValue = score.text;

Your assignment is backwards. You're (uselessly) overwriting the variable holding the string you fetched from NSUserDefaults with the current value of the text field.


I think what you want is

score.text = savedValue;

The following line is also not really doing anything:

[[NSUserDefaults standardUserDefaults] objectForKey:@"Score"];


I'm assuming in the second view controller, score is the name of your label?

If so, you should say

score.text = savedValue;
