title: UITextView - some fonts cause text to disappear
body: <p>I'm having an interesting problem with <code>UITextView</code>. I use this code to put a text view on the screen in <code>loadView</code> of a view controller:</p>
  
  <pre><code>self.textView = [[UITextView alloc] init];
  if (self.tutorialPage.text.length &gt; 0)
  {
      self.textView.backgroundColor = [UIColor clearColor];
      self.textView.editable = NO;
      self.textView.text = self.tutorialPage.text;
      self.textView.showsVerticalScrollIndicator = NO;
      self.textView.textColor = [UIColor whiteColor];
      self.textView.textAlignment = NSTextAlignmentLeft;
      self.textView.translatesAutoresizingMaskIntoConstraints = NO;
      //Later constraints are added
  }
  
  UIFont *font = [UIFont fontWithName:@"Noteworthy-Bold" size:(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ? 20.0 : 15.0)];
  self.textView.font = font;
  [self.view addSubview:self.textView];
  </code></pre>
  
  <p>Every line of this code gets called, by the way, and the text view is definitely onscreen. But somehow, when this same code is called again to create another view controller of the same type, the text doesn't show up. When I select text in the text view by tapping and holding, though, the text suddenly appears.</p>
  
  <p>Even weirder, when I change this line</p>
  
  <pre><code>UIFont *font = [UIFont fontWithName:@"Noteworthy-Bold" size:(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ? 20.0 : 15.0)];
  </code></pre>
  
  <p>to use a different font name, such as <code>@"Noteworthy-Light"</code>, or <code>@"TimesNewRomanPS-BoldMT"</code>, the text view behaves as expected... What could be the cause of this problem?</p>
  
  <p>Has anyone ever seen this problem before? If so, please share how you solved it or worked around it.</p>
