title: UIButton custom font vertical alignment
body: <p>I've got a <code>UIButton</code> which uses a custom font, which is set when my view loads:</p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];    
      self.searchButton.titleLabel.font = [UIFont fontWithName: @"FONTNAME" size: 15.0 ];
  }
  </code></pre>
  
  <p>The problem I've got is that the font is appearing to float up of the center line. If I comment out this line, the default font appears vertically centered fine. But changing to the custom font breaks the vertical alignment.</p>
  
  <p>I'm getting the same issue on a Table Cell with a custom font too.</p>
  
  <p>Do I need to tell the view somewhere that the custom font is not as tall as other fonts?</p>
  
  <p>EDIT: I've just realized that the font I'm using is a Windows TrueType Font. I can use it fine in TextEdit on the Mac, only a problem with the alignment in my App</p>
