title: Why doesn't UIButton title display?
body: <p>In a UIViewController's viewDidLoad method, I do this:</p>
  
  <pre><code>UIButton *b = [[UIButton buttonWithType:UIButtonTypeRoundedRect] 
                                         initWithFrame:CGRectMake(0, 0, 100, 100)];
  
  [b setTitle:@"Testing" forState:UIControlStateNormal];
  [b setTitleColor: [UIColor blackColor] forState: UIControlStateNormal];
  [self.view addSubview:b];                       // EDIT: should be 'b'
  NSLog(@"button title: %@", [b titleLabel].text);
  </code></pre>
  
  <p>The button displays but the title doesn't.  The NSLog line prints "Testing" to the console.  Any suggestions on what I'm doing wrong?</p>
