This solved my problem.
UILabel *scoreLabel = [ [UILabel alloc ] initWithFrame:CGRectMake((self.bounds.size.width / 2), -50.0, 100.0, 100.0) ];
scoreLabel.textAlignment = UITextAlignmentCenter;
scoreLabel.textColor = [UIColor whiteColor];
scoreLabel.backgroundColor = [UIColor blackColor];
scoreLabel.font = [UIFont fontWithName:@"Arial Rounded MT Bold" size:(36.0)];
[self addSubview:scoreLabel];
scoreLabel.text = [NSString stringWithFormat: @"Test"];
