title: can't get word wrap to work on UIButton
body: <p>I have a simple UIButton and try to get word wrap but it always shows the text in one line exceeding the button size.</p>
  
  <pre><code> NSString * text = NSLocalizedString(@"Start Loading",@"Start Loading");
  _continueBtn.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
  _continueBtn.titleLabel.textAlignment = NSTextAlignmentCenter;
  [_continueBtn setTitle:text forState:UIControlStateNormal];
  </code></pre>
  
  <p>Also in UI builder when I set word wrap there the text wraps - only when I run the app the text appears in one line.</p>
  
  <p>What have I missed here?</p>
