I have a text view in my project and I want when user tap the text field it moves up equals to the height of the keyboard I used this code for getting height of the keyboard and It gives me the size of the keyboard

static var sizeForOffsetKeyboard = CGFloat()

    var heightKeyboard : CGFloat?
override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardShown(notification:)), name: NSNotification.Name.UIKeyboardDidShow, object: nil)
}

func keyboardShown(notification: NSNotification) {
    if let infoKey  = notification.userInfo?[UIKeyboardFrameEndUserInfoKey],
        let rawFrame = (infoKey as AnyObject).cgRectValue {
        let keyboardFrame = view.convert(rawFrame, from: nil)
        self.heightKeyboard = keyboardFrame.size.height

        levelChatViewController.sizeForOffsetKeyboard = heightKeyboard!

        print(levelChatViewController.sizeForOffsetKeyboard)
        // Now is stored in your heightKeyboard variable
    }
}

But I didn't get the result and the textview won't move up with the height of the keyboard

so here is the codes for offset textview 

func textViewDidBeginEditing(_ textView: UITextView) {


   animateViewMoving(up: true, moveValue: levelChatViewController.sizeForOffsetKeyboard)
}

  • You can use UITableViewController for automatic scrolling. Check my ans here https://stackoverflow.com/questions/45233089/move-textfield-up-when-keyboard-displays/45233564#45233564 – luckyShubhra Aug 05 '17 at 05:00
  • I used https://stackoverflow.com/questions/26070242/move-view-with-keyboard-using-swift and its ok But when textfield is editing and user change the keyboard the textfield won't move with new keyboard – Saeed Rahmatolahi Aug 05 '17 at 05:19
  • You have to keep on adding height when keyboard based on which textfiled is currently selected. You can use UITableViewController and you can achieve what you desire with zero code. – luckyShubhra Aug 05 '17 at 05:22
  • You can check ans by Celil and Fedya and Rohit in link you shared. Those ans can be helpful in your case. – luckyShubhra Aug 05 '17 at 05:26
  • I didn't used UITableViewController and because of lots of codes I can't change it can you give me another way ? – Saeed Rahmatolahi Aug 05 '17 at 05:37
  • Have you checked ans by Celil and Fedya and Rohit in link you shared above?? – luckyShubhra Aug 05 '17 at 05:38
  • I know you would have to change it no issues. You can keep UITableViewController for future when in need. – luckyShubhra Aug 05 '17 at 05:39

Easiest way is to use IQKeyboardManagerSwift

Add pod 

      pod 'IQKeyboardManagerSwift'

In your AppDelegate

     import IQKeyboardManagerSwift

inside didFinishLaunchingWithOptions

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    IQKeyboardManager.sharedManager().enable = true

     }

This will manage all the text filed of your project and you do not have to write anything anywhere else

Just try it once you will love it
