title: UIButton with two lines of text in the title (numberOfLines=2)
body: <p>I'm trying to make a <code>UIButton</code> that has two lines of text in its titleLabel. This is the code I'm using:</p>
  <pre><code>UIButton *titleButton = [[UIButton alloc] initWithFrame:CGRectMake(15, 10, frame.size.width-100, 100)];
  titleButton.titleLabel.font = [UIFont boldSystemFontOfSize:24.0];
  [titleButton setTitle:@&quot;This text is very long and should get truncated at the end of the second line&quot; forState:UIControlStateNormal];
  titleButton.titleLabel.lineBreakMode = UILineBreakModeTailTruncation;
  titleButton.titleLabel.numberOfLines = 2;
  [self addSubview:titleButton];
  </code></pre>
  <p>When I try this, the text only appears on one line. It seems the only way to achieve more than one line of text in <code>UIButton.titleLabel</code> is to set <code>numberOfLines=0</code> and use <code>UILineBreakModeWordWrap</code>. But this doesn't guarantee the text to be exactly two lines.</p>
  <p>Using a plain <code>UILabel</code>, however, does work:</p>
  <pre><code>UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(15, 10, frame.size.width-100, 100)];
  titleLabel.font = [UIFont boldSystemFontOfSize:24.0];
  titleLabel.text = @&quot;This text is very long and should get truncated at the end of the second line&quot;;
  titleLabel.numberOfLines = 2;
  titleLabel.lineBreakMode = UILineBreakModeTailTruncation;
  [self addSubview:titleLabel];
  
      
  </code></pre>
  <p>Does anyone know how to make the <code>UIButton</code> work with two lines? Is the only solution to create a separate <code>UILabel</code> to hold the text, and add it as a subview of the button?</p>
