Question

The app in question is a simple sample program. In my view controller header, I have the button instantiated as such:

@interface ObscurelyNamedViewController : UIViewController {
    UIButton *yoButton;
}
@property(nonatomic, retain) IBOutlet UIButton *yoButton;

- (IBAction)yoButtonPressed:(id)sender;

yoButtonPressed: is implemented as such:

[yoButton setTitle: @"I said 'yo', jammit!" forState: UIControlStateNormal];
// repeat for other button states
.
.
.

In Interface Builder, I have connected the Touch Up Inside event of the UIButton to the yoButtonPressed method in the File’s Owner of the ObscurelyNamedViewController to recognize the touch. In return, I have connected the outlet of the File’s Owner back to the yoButton, so as to enable the updating of it’s title.

When I build and run, I get no errors, but nothing displays and the app immediately quits. The only other thing living in IB is a UIImage view. Am I missing something or have I wired something incorrectly?

EDIT: In the console, I see the following message:

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "BradiiCaliiViewController" nib but the view outlet was not set.'

Moved from comment on Lou Franco answer:

BradiiCaliiViewController complains that it doesn’t have a view even after NIB was loaded. You have to connect view outlet of File’s Owner to your view in BradiiCaliiViewController’s XIB.
