title: UITextView border not appearing
body: <pre><code>- (void)setupTextviewBorder {
  self.descTextView.layer.borderWidth = 50.0;
  float f = 197.0/255.0;
  self.descTextView.layer.borderColor = (__bridge CGColorRef)([UIColor colorWithRed:f green:f blue:f alpha:1]);
  self.descTextView.layer.cornerRadius = 20.0;
  self.descTextView.layer.masksToBounds = true;

  </code></pre>
  
  <p>yes I am calling this method and I can log the layer. When I view it, I see no border.</p>
