Scroll UITextField above Keyboard in a UITableViewCell on a regular UIViewController

Question

I have tried most of the examples here on StackOverflow. I also used Apple\'s. The problem I seem to have with them is that they don\'t account for the UITextField being in

Answer 1

I made a mix with the answers of Matt and also Salman. This works for many textfields in a tableView. Swift 3

Basically is get the BOTTOM Y point of the textInput touched. Once we have that I check if the keyboard cover the textInput and if do it I would change the contentOffset of the tableView

First register to the notifications. In the init if is a UIView or in viewDidLoad if is a UIViewController:

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

Then set up the textfield touched as current input

var inputActive: UITextField!

func textViewShouldBeginEditing(_ textView: UITextView) -> Bool {
    inputActive = textInput
    return true
}

Finally implement the notifications method:

func keyboardWillShow(notification: NSNotification) {
    var userInfo = notification.userInfo!
    if let keyboardFrame = (userInfo[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        // Get my height size
        let myheight = tableView.frame.height
        // Get the top Y point where the keyboard will finish on the view
        let keyboardEndPoint = myheight - keyboardFrame.height
        // Get the the bottom Y point of the textInput and transform it to the currentView coordinates.
        if let pointInTable = inputActive.superview?.convert(inputActive.frame.origin, to: tableView) {
            let textFieldBottomPoint = pointInTable.y + inputActive.frame.size.height + 20
            // Finally check if the keyboard will cover the textInput
            if keyboardEndPoint <= textFieldBottomPoint {
                tableView.contentOffset.y = textFieldBottomPoint - keyboardEndPoint
            } else {
                tableView.contentOffset.y = 0
            }
        }
    }
}

func keyboardWillHide(notification: NSNotification) {
    tableView.contentOffset.y = 0
}

Few things to add. The padding is some extra distance that I add in my case was 20 points. Also in my case the UITableView was added to a UIViewController but this should work also in a UITableViewController

Hope this helps!
