Move Textfield When Keyboard Appears Swift

Move textfield when keyboard appears swift

There are a couple of improvements to be made on the existing answers.

Firstly the UIKeyboardWillChangeFrameNotification is probably the best notification as it handles changes that aren't just show/hide but changes due to keyboard changes (language, using 3rd party keyboards etc.) and rotations too (but note comment below indicating the keyboard will hide should also be handled to support hardware keyboard connection).

Secondly the animation parameters can be pulled from the notification to ensure that animations are properly together.

There are probably options to clean up this code a bit more especially if you are comfortable with force unwrapping the dictionary code.

 class MyViewController: UIViewController {

   // This constraint ties an element at zero points from the bottom layout guide
   @IBOutlet var keyboardHeightLayoutConstraint: NSLayoutConstraint?
 
   override func viewDidLoad() {
     super.viewDidLoad()
     NotificationCenter.default.addObserver(self,
       selector: #selector(self.keyboardNotification(notification:)),
       name: UIResponder.keyboardWillChangeFrameNotification,
       object: nil)
   }
 
   deinit {
     NotificationCenter.default.removeObserver(self)
   }
 
   @objc func keyboardNotification(notification: NSNotification) {
     guard let userInfo = notification.userInfo else { return }

     let endFrame = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue
     let endFrameY = endFrame?.origin.y ?? 0
     let duration:TimeInterval = (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 = UIView.AnimationOptions(rawValue: animationCurveRaw)

     if endFrameY >= UIScreen.main.bounds.size.height {
       self.keyboardHeightLayoutConstraint?.constant = 0.0
     } else {
       self.keyboardHeightLayoutConstraint?.constant = endFrame?.size.height ?? 0.0
     }

     UIView.animate(
       withDuration: duration,
       delay: TimeInterval(0),
       options: animationCurve,
       animations: { self.view.layoutIfNeeded() },
       completion: nil)
   }
}

Move view with keyboard using Swift

Here is a solution, without handling the switch from one textField to another:

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

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

To solve this, replace the two functions keyboardWillShow/Hide with these:

func keyboardWillShow(notification: NSNotification) {        
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.CGRectValue() {
        if view.frame.origin.y == 0 {
            self.view.frame.origin.y -= keyboardSize.height
        }
    }        
}

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

Swift 3.0:

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

@objc func keyboardWillShow(notification: NSNotification) {        
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        if self.view.frame.origin.y == 0 {
            self.view.frame.origin.y -= keyboardSize.height
        }
    }        
}

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

Swift 4.0:

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

@objc func keyboardWillShow(notification: NSNotification) {        
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        if self.view.frame.origin.y == 0 {
            self.view.frame.origin.y -= keyboardSize.height
        }
    }        
}

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

Swift 4.2:

override func viewDidLoad() {
    super.viewDidLoad()            
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)
}

@objc func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        if self.view.frame.origin.y == 0 {
            self.view.frame.origin.y -= keyboardSize.height
        }
    }
}

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

Keyboard covers text fields at the bottom of my view

This code will work, making your textField animating to above keyboard if its frame intersects with that of keyboard and animating back to original position on keyboard hide.

@IBOutlet weak var textField: UITextField!

  var offsetY:CGFloat = 0

  override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    NotificationCenter.default.addObserver(self, selector: #selector(ViewController.keyboardFrameChangeNotification(notification:)), name: NSNotification.Name.UIKeyboardWillChangeFrame, object: nil)
  }

  func keyboardFrameChangeNotification(notification: Notification) {
    if let userInfo = notification.userInfo {
      let endFrame = userInfo[UIKeyboardFrameEndUserInfoKey] as? CGRect
      let animationDuration = userInfo[UIKeyboardAnimationDurationUserInfoKey] as? Double ?? 0
      let animationCurveRawValue = (userInfo[UIKeyboardAnimationCurveUserInfoKey] as? Int) ?? Int(UIViewAnimationOptions.curveEaseInOut.rawValue)
      let animationCurve = UIViewAnimationOptions(rawValue: UInt(animationCurveRawValue))
      if let _ = endFrame, endFrame!.intersects(self.textField.frame) {
        self.offsetY = self.textField.frame.maxY - endFrame!.minY
        UIView.animate(withDuration: animationDuration, delay: TimeInterval(0), options: animationCurve, animations: {
          self.textField.frame.origin.y = self.textField.frame.origin.y - self.offsetY
        }, completion: nil)
      } else {
        if self.offsetY != 0 {
          UIView.animate(withDuration: animationDuration, delay: TimeInterval(0), options: animationCurve, animations: {
            self.textField.frame.origin.y = self.textField.frame.origin.y + self.offsetY
            self.offsetY = 0
          }, completion: nil)
        }
      }
    }
  }

moving View up with textfield and Button when keyboard appear Swift

Here is solution, Create bottom layout constraint reference of send button view

@IBOutlet weak var bottomConstraint: NSLayoutConstraint!
@IBOutlet weak var sendbuttonView: UIView!

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

    override func viewWillDisappear(_ animated: Bool) {
        NotificationCenter.default.removeObserver(self)
    }

    @objc func handleKeyboardNotification(_ notification: Notification) {

    if let userInfo = notification.userInfo {

        let keyboardFrame = (userInfo[UIKeyboardFrameEndUserInfoKey] as AnyObject).cgRectValue

        let isKeyboardShowing = notification.name == NSNotification.Name.UIKeyboardWillShow

        bottomConstraint?.constant = isKeyboardShowing ? -keyboardFrame!.height : 0

        UIView.animate(withDuration: 0.5, animations: { () -> Void in
            self.view.layoutIfNeeded()
        })
    }
}

Demo example

Move textfield up when keyboard appears leaves black bar behind

1. Register keyboard Hide and Show Notification in you viewDidLoad()

 NotificationCenter.default.addObserver(self, selector: 
 #selector(keyBoardWillShow(notification:)), name: 
 .UIKeyboardWillShow , object: nil)

NotificationCenter.default.addObserver(self, selector: 
#selector(keyBoardWillHide(notification:)), name: .UIKeyboardWillHide 
, object: nil)

2. Called when keyboard hide and show

@objc func keyBoardWillShow(notification: NSNotification){
    adjustInsetForKeyBoards(show: true, notification: notification)
}

@objc func keyBoardWillHide(notification: NSNotification){
    adjustInsetForKeyBoards(show: false, notification: notification)
}

3. Your logic to show and hide the keyboard with animation

func adjustInsetForKeyBoards(show: Bool, notification: NSNotification){
  let userInfo = notification.userInfo ?? [:]

  let keyboardFrame = (userInfo[UIKeyboardFrameBeginUserInfoKey] as! NSValue).cgRectValue
  let adjustment = (keyboardFrame.height * (show ? 1 : -1)) + 20
            self.yourView.contentInset.bottom += adjustment
}

Move UITextField up when keyboard appears

Try this code

func textFieldDidBeginEditing(textField: UITextField!)
{
     self.scrollView.setContentOffset(CGPoint.init(x: 0, y: scrollBy), animated: true)
  // scrollBy - pass the height you want your scrollview to be scrolled when keyboard appears
 }

func textFieldDidEndEditing(textField: UITextField!)
{
    self.scrollView.setContentOffset(CGPoint.init(x: 0, y: 0), animated: true)

    self.view.endEditing(true);
}

Move menu when the keyboard opens (Swift)

you can set the constraints according to the size of your screen

if self.view.height >= 800{ //For bigger screens (X ,11)
    self.keyboardConstrains.constant = keyboardFrame.size.height - 50
} else {
    self.keyboardConstrains.constant = keyboardFrame.size.height
}
