UIButton Custom Font not showing

I've checked out the other similar questions and done what's listed in those, I think, but my custom font is still not showing on a UI button.

The font is in the project, and it is appearing correctly in my UITableViewCells, so I know the font works fine.

I'm loading the view, and assigning the font to the button, but when I run the app it's not showing up the correct font.

FirstViewController.h

@interface FirstViewController : UIViewController <UITextFieldDelegate, UITableViewDelegate, UITableViewDataSource> {
    ...    
    UIButton *searchButton;
    ...
}

...
@property (nonatomic, retain) IBOutlet UIButton *searchButton;
...

@end

Then I've got this in FirstViewController.m

@开发者_如何学JAVAsynthesize searchButton;

- (void)viewDidLoad
{
    [super viewDidLoad];    

    self.searchButton.titleLabel.font = [UIFont fontWithName: @"FontFile" size: 11.0 ];
}

What have I done wrong?

[self.searchButton setTitle:@"ButtonTitle" forState:UIControlStateNormal];

As jamihash pointed out, I hadn't hooked up the button from IB to the code. Doing that fixed it.
