我修改了一点@Simpa解决方案.........

override func viewDidLoad() 
{

    super.viewDidLoad()
    NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("makeSpaceForKeyboard:"), name:UIKeyboardWillShowNotification, object: nil);
    NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("makeSpaceForKeyboard:"), name:UIKeyboardWillHideNotification, object: nil);
}

deinit{
    NSNotificationCenter.defaultCenter().removeObserver(self)
}

var keyboardIsVisible = false
override func makeSpaceForKeyboard(notification: NSNotification) {

    let info = notification.userInfo!
    let keyboardHeight:CGFloat = (info[UIKeyboardFrameEndUserInfoKey] as! NSValue).CGRectValue().size.height
    let duration:Double = info[UIKeyboardAnimationDurationUserInfoKey] as! Double

    if notification.name == UIKeyboardWillShowNotification && keyboardIsVisible == false{

        keyboardIsVisible = true

        UIView.animateWithDuration(duration, animations: { () -> Void in
            var frame = self.view.frame
            frame.size.height = frame.size.height - keyboardHeight
            self.view.frame = frame
        })

    } else if keyboardIsVisible == true && notification.name == UIKeyboardWillShowNotification{

    }else {
        keyboardIsVisible = false

        UIView.animateWithDuration(duration, animations: { () -> Void in
            var frame = self.view.frame
            frame.size.height = frame.size.height + keyboardHeight
            self.view.frame = frame
        })
    }
}

我使用的Swift 4解决方案需要键盘大小。将serverStatusStackView替换为任何你关心的视图，例如:self.view:

deinit {
    NotificationCenter.default.removeObserver(self)
}

@objc func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        serverStatusStackView.frame.origin.y = keyboardSize.height * 2 - serverStatusStackView.frame.height
    }
}

@objc func keyboardWillHide(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        serverStatusStackView.frame.origin.y += keyboardSize.height
    }
}

override func viewDidLoad() {
    super.viewDidLoad()
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(notification:)), name: NSNotification.Name.UIKeyboardWillShow, object: nil)

    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(notification:)), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

你可以使用这个库，只需一行代码在appDidFinishedLaunching和你完成。

func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    IQKeyboardManager.sharedManager().enable = true
    return true
}

斯威夫特4。x答案，合并来自@Joseph Lord和@Isuru的答案。bottomConstraint表示你想移动的视图的底部约束。

override func viewDidLoad() {
    // Call super
    super.viewDidLoad()

    // Subscribe to keyboard notifications
    NotificationCenter.default.addObserver(self,
                                           selector: #selector(keyboardNotification(notification:)),
                                           name: UIResponder.keyboardWillChangeFrameNotification,
                                           object: nil)        
}


deinit {
    NotificationCenter.default.removeObserver(self)
}


@objc func keyboardNotification(notification: NSNotification) {
    if let userInfo = notification.userInfo {
        // Get keyboard frame
        let keyboardFrame = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as! NSValue).cgRectValue

        // Set new bottom constraint constant
        let bottomConstraintConstant = keyboardFrame.origin.y >= UIScreen.main.bounds.size.height ? 0.0 : keyboardFrame.size.height

        // Set animation properties
        let duration = (userInfo[UIResponder.keyboardAnimationDurationUserInfoKey] as? NSNumber)?.doubleValue ?? 0
        let animationCurveRawNSN = userInfo[UIResponder.keyboardAnimationCurveUserInfoKey] as? NSNumber
        let animationCurveRaw = animationCurveRawNSN?.uintValue ?? UIView.AnimationOptions.curveEaseInOut.rawValue
        let animationCurve = UIView.AnimationOptions(rawValue: animationCurveRaw)

        // Animate the view you care about
        UIView.animate(withDuration: duration, delay: 0, options: animationCurve, animations: {
            self.bottomConstraint.constant = bottomConstraintConstant
            self.view.layoutIfNeeded()
        }, completion: nil)
    }
}

以下是我对Swift 2.2的解决方案:

首先注册键盘显示/隐藏通知

NSNotificationCenter.defaultCenter().addObserver(self,
                                                 selector: #selector(MessageThreadVC.keyboardWillShow(_:)),
                                                 name: UIKeyboardWillShowNotification,
                                                 object: nil)
NSNotificationCenter.defaultCenter().addObserver(self,
                                                 selector: #selector(MessageThreadVC.keyboardWillHide(_:)),
                                                 name: UIKeyboardWillHideNotification,
                                                 object: nil)

然后在与这些通知相对应的方法中，向上或向下移动主视图

func keyboardWillShow(sender: NSNotification) {
if let keyboardSize = (sender.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.CGRectValue() {
  self.view.frame.origin.y = -keyboardSize.height
  }
}

func keyboardWillHide(sender: NSNotification) {
self.view.frame.origin.y = 0
}

诀窍在于“keyboardWillShow”部分，每次“QuickType建议栏”被展开或折叠时，该部分都会被调用。然后我们总是设置主视图的y坐标等于键盘总高度的负值(包括或不包括“QuickType栏”部分)。

最后不要忘记删除观察者

deinit {
NSNotificationCenter.defaultCenter().removeObserver(self)
}

管理键盘的完整代码。

        override func viewWillAppear(_ animated: Bool) {
            NotificationCenter.default.addObserver(self, selector: #selector(StoryMediaVC.keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
            NotificationCenter.default.addObserver(self, selector: #selector(StoryMediaVC.keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)
        }
        override func viewWillDisappear(_ animated: Bool) {
            NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillShowNotification, object: nil)
            NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillHideNotification, object: nil)
        }
        @objc func keyboardWillShow(notification: NSNotification) {
            guard let userInfo = notification.userInfo else {return}
            guard let keyboardSize = userInfo[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue else {return}
            let keyboardFrame = keyboardSize.cgRectValue

            if self.view.bounds.origin.y == 0{
                self.view.bounds.origin.y += keyboardFrame.height
            }
        }


        @objc func keyboardWillHide(notification: NSNotification) {
            if self.view.bounds.origin.y != 0 {
                self.view.bounds.origin.y = 0
            }
        }
