Question

In class 1 i save a int converted to a string, in class 2 I try to load this string for some reason it does not work, when I write the string which I get out of loadString to a text box in class 2 the text box stays empty.
When i do the same thing in class 1 the text box becomes “1”.

class 1.m

- (void)viewDidLoad
{
[super viewDidLoad];
countForString = 1;
saveString = [[NSString alloc]initWithFormat:@"%i", countForString];
[self SaveTextBox:saveString :@"Number"];
}

-(void)SaveTextBox:(NSString*)string :(NSString*)stringsave
{
NSString *savestring = string;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:savestring forKey:stringsave];
[defaults synchronize];
}

class 2.m

- (void)viewDidLoad
{
[super viewDidLoad];
[self loadString:@"Number":teamString];
tbTeamPlayer.text = teamString;
}

-(void)loadString:(NSString *)location:(NSString *)saveInString
{
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *loadstring = [defaults objectForKey:location];
saveInString = loadstring;
} 

Answer 1

loadString:location: doesn’t change the value of saveInString, all it does is overwrite the local variable. You need to return the string and set that value, e.g.

tbTeamPlayer.text = [self loadString:someLocation];

and change loadString to do:

- (NSString *)loadString:(NSString *)location
{
    return [[NSUserDefaults standardUserDefaults] stringForKey:location];
}
