Hey guys,

I've got a text field, and in it I want it to save the data when I click a button.

I do this code when I click a button:

Code:
[[NSUserDefaults standardUserDefaults] setObject:[codeTextField stringValue] forKey:@"RegistrationCode"];

And in awakeFromNib I do this code to load what was in the text field back in:

Code:
[codeTextField setStringValue:[[NSUserDefaults standardUserDefaults] stringForKey:@"RegistrationCode"]];

But for some reason, I get this weird crash on startup, here is what it says:

2004-04-24 21:01:12.914 Tag[4392] *** Assertion failure in -[NSTextFieldCell _objectValue:forString:], AppKit.subproj/NSCell.m:1131
2004-04-24 21:01:12.925 Tag[4392] An uncaught exception was raised
2004-04-24 21:01:12.931 Tag[4392] Invalid parameter not satisfying: aString != nil
2004-04-24 21:01:12.938 Tag[4392] *** Uncaught exception: <NSInternalInconsistencyException> Invalid parameter not satisfying: aString != nil

«PROJECTNAME» has exited due to signal 5 (SIGTRAP).

I am totally at lost here, as I get no warnings or errors when building, any ideas appreciated .

Thanks,
Oliver

apparently, I need to check if my preferences are nil, but Im not sure how to do this? Any ideas?

Maybe something like this...

Code:
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSString *regCode = [defaults stringForKey:@"RegistrationCode"];
    
    //Check to see if regCode is nil, then set regCode as a default value
    if (regCode == nil) regCode = @"";
    [codeTextField setStringValue:regCode];
    
    //or
    
    //Check to see if regCode is nil, then perform an action
    if (regCode == nil) {
        NSLog(@"Registration code is nil.");
    } else {
        [codeTextField setStringValue:regCode];
    }

(Tags looking great by the way )
