swift 弹出键盘view自动上升
一、设置监听键盘事件函数：
override func viewWillAppear(animated: Bool) { NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillShow:", name: UIKeyboardWillShowNotification, object: nil) NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillHide:", name: UIKeyboardWillHideNotification, object: nil) }
二、处理弹出事件：
func keyboardWillShow(notification:NSNotification){if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() { //let contentInsets = UIEdgeInsets(top: 0, left: 0, bottom: keyboardSize.height, right: 0) //let keyboardheight = keyboardSize.height as CGFloat //let frame = self.nameInput.frame // frame.origin.y = frame.origin.y - keyboardheight //var offset = 156 as CGFloat var width = self.view.frame.size.width; var height = self.view.frame.size.height; let rect = CGRectMake(0.0, -156,width,height); self.view.frame = rect } }
三、处理收回事件：
func keyboardWillHide(notification:NSNotification){ self.view.addSubview(logoArea) var width = self.view.frame.size.width; var height = self.view.frame.size.height; let rect = CGRectMake(0.0, 0,width,height); self.view.frame = rect }
