title: How to set the title text color of UIButton?
body: <p>I tried changing the colors of the text for a button, but it's still staying white.</p>
  
  <pre><code>isbeauty = UIButton()
  isbeauty.setTitle("Buy", forState: UIControlState.Normal)
  isbeauty.titleLabel?.textColor = UIColorFromRGB("F21B3F")
  isbeauty.titleLabel!.font = UIFont(name: "AppleSDGothicNeo-Thin" , size: 25)
  isbeauty.backgroundColor = UIColor.clearColor()
  isbeauty.layer.cornerRadius = 5
  isbeauty.layer.borderWidth = 1
  isbeauty.layer.borderColor = UIColorFromRGB("F21B3F").CGColor
  isbeauty.frame = CGRectMake(300, 134, 55, 26)
  isbeauty.addTarget(self,action: "first:", forControlEvents: UIControlEvents.TouchUpInside)
  self.view.addSubview(isbeauty)
  </code></pre>
  
  <p>I also tried changing it the red, black, blue, but nothing is happening.</p>
