I'm coding a program in Objective C that uses two different views to input data. One view merely displays the view (PSACurrentGame) and the other inputs the data (PSAEnterScores). I'm using a "prepareforsegue" method to pass data from PSAEnterScores to PSACurrentGame. The problem is the label isn't changing. Any idea why?

Log after one time inputing data:
2013-11-25 19:04:08.810 Phase 10 Scoring Application[34601:11303] Unknown class PSA in Interface Builder file.
2013-11-25 19:08:11.607 Phase 10 Scoring Application[34601:11303] Value of P1ToScore: (null)
(The Name of the program is Phase 10 Scoring Application)
I have no idea why it says Unknown class PSA in Interface Builder file. I have no class named "PSA", it is merely the prefix for my classes.
prepareForSegue: is called before viewDidLoad: so your IBOutlet will be nil. Try setting the incoming value to a NSString and then use that string to populate the UIlabel on viewDidLoad:
For example
In your PSACurrentGame.h: // create a property @property(nonatomic,strong)NSString *gameName;
In your PSAEnterScores.m: modify your
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
PSACurrentGame *pass = (PSACurrentGame *)segue.destinationViewController;
pass.gameName=[NSString alloc]initWithString:pass.R2P1Score.text]
}
In your PSACurrentGame.m :
- (void)viewDidLoad
{
[super viewDidLoad];
// set text to your label
R3P1Score.text=gameName;
}
