saving user defaults [iOS]

I saw a couple of examples but I cannot figure out what's going wrong when trying to save my text field input and reload it when restarting the app. I have something like this in my .m file (.h file only has a <UITextViewDelegate>);

@implementation C4WorkSpace{
    UITextView *textField;
    C4Button *okButton;
    C4Label *savedText;
}

-(void)setup {
    //add text field
    CGRect textViewFrame = CGRectMake(20.0f, 20, self.canvas.width-40, 124.0f);
    textField = [[UITextView alloc] initWithFrame:textViewFrame];
    textField.returnKeyType = UIReturnKeyDone;
    [textField becomeFirstResponder];
    textField.delegate = self;
    //textField.hidden=true;

    [self.view addSubview:textField];

    okButton=[C4Button buttonWithType:ROUNDEDRECT];
    [okButton setTitle:@"Save" forState:NORMAL];
    okButton.center=self.canvas.center;
    [self.canvas addUIElement:okButton];
    [okButton runMethod:@"saveDefault" target:self forEvent:TOUCHUPINSIDE];

    savedText=[C4Label labelWithText:@"default"];
    savedText.center=CGPointMake(self.canvas.center.x, self.canvas.center.y+40);
    [self.canvas addLabel:savedText];
}
-(void)saveDefault{
    NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];

    [defaults setObject:textField.text forKey:@"userName"];
    [defaults synchronize];
    C4Log(@"defaults: %@",defaults);
    C4Log(@"defaults: %@", [defaults objectForKey:@"userName"]);
    savedText.text=textField.text;
}
-(void)viewDidLoad{
    NSMutableString *text=[[NSUserDefaults standardUserDefaults] objectForKey:@"userName"];
    C4Log(@"loadedText:%s", text);
    textField.text=text;
    savedText.text=text;
}
@end

I'm not sure what exactly is going wrong, but when I restart the app the loadedText is always: "¯8*:å". Doesn't matter what I saved.

I found the easiest solution is to set in

ViewDidLoad

text=[[NSUserDefaults standardUserDefaults] objectForKey:@"userName"];

and in setup

if (text!=nil) {
        textField.text=text;
    }
