title: Rounded border on UIButton has disappeared
body: <p>I had a rounded UIButton in a custom table view cell initialized via a <code>XIB</code>, and it was working fine. I just noticed that the border, a circular pink border, now doesn't appear. I tried adding some code to also set the property in the <code>awakeFromNib</code> function, but this also didn't do the trick. </p>
  
  <pre><code>- (void)awakeFromNib {
      [super awakeFromNib];
      [self setupProfileView];
      self.contentView.backgroundColor = [UIColor colorWithWhite:0.97f alpha:1.0f];
      self.selectionStyle = UITableViewCellSelectionStyleNone;
      _initialLabel.layer.cornerRadius = _initialLabel.frame.size.width/2;
      _initialLabel.layer.borderWidth = 2;
      _initialLabel.layer.borderColor = [UIColor colorWithRed:223.0/255.0 green:158.0/255.0 blue:255.0/255.0 alpha:1].CGColor;
      NSLog(@"on profile table view cell border width is %f and radius is %f and color is %@", _initialLabel.layer.cornerRadius, _initialLabel.layer.borderWidth, _initialLabel.layer.borderColor);
  }
  </code></pre>
  
  <p>The above prints out what I would expect (the correct color + radius + width), but it doesn't show in the view. It's the only reference in code to <code>_initialLabel</code>, so it's not getting set somewhere else in code. </p>
  
  <p>Has anyone run into this and know a fix? Any ideas how to troubleshoot this further?</p>
