UITableViewController not scrolling view when keyboard appears

Question

I have a UITableViewController with around 20 static cells, some of these cells have UITextFields within them and some are just for selecting with

Answer 1

If the auto scroll of UITableViewController doesn't work with the UITextFields in cells or scroll weirdly, do these steps. Swift 5 iOS 13.2 tested 100%

First implement viewWillAppear but don't call super.viewWillAppear (this will stop auto scroll)

override func viewWillAppear(_ animated: Bool) {

}

Then let's do the scroll manually.

override func viewWillAppear(_ animated: Bool) {

  //Notification center observers
  NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(notification:)),
                                             name: UIResponder.keyboardDidShowNotification, object: nil)
  NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(notification:)),
                                            name: UIResponder.keyboardWillHideNotification, object: nil)

}

//keybord show action
@objc func keyboardWillShow(notification: Notification) {
    tableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: notification.getKeyBoardHeight, right: 0)
}
//keyboard hide action
@objc func keyboardWillHide(notification: Notification) {
    tableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
}

extension Notification {

    var getKeyBoardHeight: CGFloat {

        let userInfo: NSDictionary = self.userInfo! as NSDictionary
        let keyboardFrame: NSValue = userInfo.value(forKey: UIResponder.keyboardFrameEndUserInfoKey) as! NSValue
        let keyboardRectangle = keyboardFrame.cgRectValue
        return keyboardRectangle.height
    }

}

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

Answer 2

I ran into this issue myself. I just converted my view controller from a UIViewController to a UITableViewController in addition to adding the [super viewWillAppear:animated]; call, you will need to remove these lines:

[self.tableView setDataSource:self]; [self.tableView setDelegate:self];

As they are no longer needed and setDelegate interferes with the keyboard scrolling behavior.

I found non of these answers to be correct. After a while, I notice that if you push a controller it won't work ... but if you present it modally.. the table will automatically scroll to the used textfield.

Hope that saves time and stress to anyone.

Make sure that if you are overriding viewWillAppear that you call

[super viewWillAppear:animated];

If you don't, the Scroll View will not scroll up properly.

Swift

super.viewWillAppear(animated)
