Button Text not showing - ios

Question

When I try to post the following code, my app just shows an empty rectangle where the button's text should be. I am a beginner at xcode and I have determined this code from other tutorials.
- (void)viewDidLoad {
[super viewDidLoad];
UILabel *player1 = [[UILabel alloc]initWithFrame:CGRectMake(35, 120,130, 30)];
[player1 setText:#"Player"];
player1.layer.borderWidth = 1.0;
player1.layer.borderColor = [UIColor blackColor].CGColor;
player1.textAlignment = UITextAlignmentCenter;
[self.view addSubview: player1];
UIButton *score1 = [[UIButton alloc]initWithFrame:CGRectMake(165, 120, 60, 30)];
[score1 setTitle:#"0" forState:UIControlStateNormal];
score1.layer.borderWidth = 1.0;
score1.layer.borderColor = [UIColor blackColor].CGColor;
[self.view addSubview: score1];
UILabel *player2 = [[UILabel alloc]initWithFrame:CGRectMake(35, 150, 130, 30)];
[player2 setText:#"Opponent"];
player2.layer.borderWidth = 1.0;
player2.layer.borderColor = [UIColor blackColor].CGColor;
player2.textAlignment = UITextAlignmentCenter;
[self.view addSubview: player2];
}
Like I said, everything but the text in the button is showing up.

Answer 1

The reason why the button looks blank is because its text color is actually white. Just give it a different color and 0 will now show:
score1.layer.backgroundColor = [UIColor blackColor].CGColor;
If you don't want to change the button background color, you may want to set the text color:
[score1 setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
Read Question: [initWithFrame:frame] vs. [UIButton buttonWithType], for more about creating a UIButton with these different methods.

Answer 2

The problem is the way you're creating the button:
UIButton *score1 = [[UIButton alloc]initWithFrame:CGRectMake(165, 120, 60, 30)];
That's not how you do it. Do it like this:
UIButton *score1 = [UIButton buttonWithType:UIButtonTypeSystem];
score1.frame = CGRectMake(165, 120, 60, 30);
All will be well after that!
