重写UITextField子类的drawRect方法

class UITextFieldX: UITextField {
      override func drawRect(rect: CGRect) {
         super.drawRect(rect)

         // 键盘完成按钮
         var toolBar = UIToolbar(frame: CGRectMake(0, 0, screenSize().width, 30))
         toolBar.barStyle = UIBarStyle.Default

         var btnFished = UIButton(frame: CGRectMake(0, 0, 50, 25))
         btnFished.setTitleColor(RGB(4, 170, 174), forState: UIControlState.Normal)
         btnFished.setTitleColor(UIColor.grayColor(), forState: UIControlState.Highlighted)
         btnFished.setTitle("完成", forState: UIControlState.Normal)
         btnFished.addTarget(self, action: "finishTapped:", forControlEvents: UIControlEvents.TouchUpInside)
         var item2 = UIBarButtonItem(customView: btnFished)

         var space = UIView(frame: CGRectMake(0, 0, screenSize().width - btnFished.frame.width - 30, 25))
         var item = UIBarButtonItem(customView: space)

         toolBar.setItems([item,item2], animated: true)

         self.inputAccessoryView = toolBar
      }

      func finishTapped(sender:UIButton){
         self.resignFirstResponder()
      }

}

func screenSize() -> CGSize{
      return UIScreen.mainScreen().bounds.size
}

func RGB (r:CGFloat, g:CGFloat, b:CGFloat) -> UIColor {
      return UIColor(red: r/255.0, green: g/255.0, blue: b/255.0, alpha: 1)
}

效果如下
