        var imageview = UIImageView(frame: self.view.bounds)

        let image = UIImage(named: "1.png")

        imageview.image = image

        self.view.addSubview(imageview)

        

      //定義使用者名稱輸入框

        var text = UITextField(frame: CGRectMake(30, 100, UIScreen.mainScreen().bounds.size.width-60, 30))

        text.delegate = self

        text.keyboardType = UIKeyboardType.Default

//    第一種是遵循代理，是在代理方法中實現鍵盤的隱藏

    override func didReceiveMemoryWarning() {

        super.didReceiveMemoryWarning()

        // Dispose of any resources that can be recreated.

    }

    //第一種方法。用代理實現鍵盤的隱藏

    func textFieldShouldReturn(textField: UITextField) -> Bool {

        if (textField == self.text) {

           

            textField.resignFirstResponder()

//            self.view.becomeFirstResponder()

        }

            return true;

    }

    

//    第二種方法實現鍵盤的隱藏

      override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {

        self.text.resignFirstResponder()

        self.pwdtext.resignFirstResponder()

    }
