需要：

在键盘显示出来的时候：

动态调整界面的显示，让界面中的输入框，tabbar可以看到

搜：

swift keyboard show adjust tableview

ios – Making a UITableView scroll when text field is selected – Stack Overflow

ios – Tableview scroll content when keyboard shows – Stack Overflow

然后用代码：

let FloatKeyboardShowAndHideAnimationTime:NSTimeInterval = NSTimeInterval(0.3)

override func viewDidLoad() {

super.viewDidLoad()

。。。

        NSNotificationCenter.defaultCenter().addObserver(self,
            selector: Selector("keyboardWillShow:"),
            name: UIKeyboardWillShowNotification,
            object: nil)
        NSNotificationCenter.defaultCenter().addObserver(self,
            selector: Selector("keyboardWillHide:"),
            name: UIKeyboardWillHideNotification,
            object: nil)

。。。

}

   func keyboardWillShow(note: NSNotification) {
        if let keyboardSize = (note.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
            print("keyboardSize=\(keyboardSize)") //(0.0, 667.0, 375.0, 216.0)
            print("messageTableView.frame=\(messageTableView.frame)") //(0.0, 0.0, 375.0, 559.0)

            var adjustedTableviewFrame = messageTableView.frame
            UIView.beginAnimations(nil, context: nil)
            UIView.setAnimationBeginsFromCurrentState(true)
            UIView.setAnimationDuration(FloatKeyboardShowAndHideAnimationTime)
            adjustedTableviewFrame.size.height -= keyboardSize.height
            messageTableView.frame = adjustedTableviewFrame
            print("messageTableView.frame=\(messageTableView.frame)") //(0.0, 0.0, 375.0, 343.0)

            let convertedRect = messageTableView.convertRect(inputMessageTextField.bounds, fromView: inputMessageTextField)
            print("convertedRect=\(convertedRect)") //(16.0, 566.0, 277.0, 30.0)
            messageTableView.scrollRectToVisible(convertedRect, animated: false)

            UIView.commitAnimations()
        }
    }

    func keyboardWillHide(note: NSNotification) {
        if let keyboardSize = (note.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
            print("keyboardSize=\(keyboardSize)") //(0.0, 451.0, 375.0, 216.0)
            print("messageTableView.frame=\(messageTableView.frame)") //(0.0, 0.0, 375.0, 343.0)

            var adjustedTableviewFrame = messageTableView.frame
            UIView.beginAnimations(nil, context: nil)
            UIView.setAnimationBeginsFromCurrentState(true)
//            UIView.setAnimationDuration(0.3)
            UIView.setAnimationDuration(FloatKeyboardShowAndHideAnimationTime)
            adjustedTableviewFrame.size.height += keyboardSize.height
            print("adjustedTableviewFrame=\(adjustedTableviewFrame)") //(0.0, 0.0, 375.0, 559.0)
            messageTableView.frame = adjustedTableviewFrame
            print("messageTableView.frame=\(messageTableView.frame)") //(0.0, 0.0, 375.0, 559.0)

            UIView.commitAnimations()
        }
