self.manualInput.returnKeyType = .Search

self.manualInput.text = ""
self.manualInput.delegate = self
self.manualInput.autocapitalizationType = .AllCharacters
self.manualInput.moveX(0)
self.manualInput.changeWidth(self.view.frame.width)
self.manualInput.layer.cornerRadius = 0
self.backgroundView.addSubview(self.manualInput)
下面是按钮:
self.keyboardButton = ActionButton(x: Dimensions.xScaleValue(170), y: Dimensions.yScaleValue(495), onTitle: "Enter code", offTitle: "Enter code", onImage: "manual_entry", offImage: "manual_entry", imageOn: true, action: {
self.manualInput.becomeFirstResponder()
print("Open the input")
})
self.backgroundView.addSubview(self.keyboardButton)

NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.keyBoardWillShow), name: UIKeyboardDidShowNotification, object: nil)
