Tengo un ViewController con un UIButton adentro. Cuando hice clic, el texto en el botón desapareció. Agrego todo el setTitle para todos los estados, pero continúa desapareciendo. ¿Alguna idea

Esto es parte de mi código:

@interface AddCardViewController : UITableViewController <UITextFieldDelegate>{
UIButton *commit;
    ......

@implementation AddCardViewController

- (void)viewDidLoad{

    self.commit = [UIButton buttonWithType: UIButtonTypeCustom];

    [self setCommitProperties];

    [self.view addSubview:commit];

 .........}



- (void) setCommitProperties{

   CGRect frameTable = self.tableView.frame;

   CGRect frame = CGRectMake(frameTable.origin.x + 10, 140, frameTable.size.width - 20, 40);

   commit.frame = frame;

   [commit setBackgroundColor : [UIColor whiteColor]];

   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateNormal];
   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateSelected];
   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateHighlighted];
   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateApplication];
   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateReserved];
   [commit setTitle: NSLocalizedString(@"AddCard",@"") forState: UIControlStateDisabled];

    [commit addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchDown];    

   UIColor *color = [[[PersonalizationManager alloc] init] getColor: @"AddCardViewController" :@"Commit_Title"]; 

   [commit.titleLabel setTextColor: color];

   color = [[[PersonalizationManager alloc] init] getColor: @"AddCardViewController" :@"Commit_Border"];

   [commit.layer setBorderColor:[color CGColor]];    
   [commit.layer setBorderWidth : 0.5f];
   [commit.layer setCornerRadius : 10.0f];
}
