How to write a UILabel programmatically

I need to add a label that shows a loading string. One way to do it is

UILabel *scoreLabel = [ [UILabel alloc ] initWithFrame:CGRectMake((self.bounds.size.width / 2)-75, 0.0, 150.0, 43.0) ];
scoreLabel.textAlignment = UITextAlignmentCenter;
scoreLabel.textColor = [UIColor whiteColor];
scoreLabel.backgroundColor = [UIColor blackColor];
scoreLabel.font = [UIFont fontWithName:@"Arial Rounded MT Bold" size:(18.0)];
[self addSubview:scoreLabel];
scoreLabel.text = [NSString stringWithFormat: @"%d", @"Loading..."];

Bye
