How do we make keyboard appear below textView in swift?

Question

I have done keyboard appearing below textfield using

on View did Load adding a observer()

    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(Gold_Loan_First_ViewController.keyboardDidShow(_:)), name: UIKeyboardDidShowNotification, object: nil)

    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(Gold_Loan_First_ViewController.keyboardWillBeHidden(_:)), name: UIKeyboardWillHideNotification, object: nil)

And then updating the frame

weak var activeField: UITextField?

func textFieldDidEndEditing(textField: UITextField) {
    self.activeField = nil


}
func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {
    if textField==txtOTP {
        txtOTP.errorMessage=""
    }
  return true
}
func textFieldDidBeginEditing(textField: UITextField) {
    self.activeField = textField

}




func keyboardDidShow(notification: NSNotification)
{
    if let activeField = self.activeField,
        let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
        let contentInsets = UIEdgeInsets(top: 0.0, left: 0.0, bottom: keyboardSize.height, right: 0.0)
        self.scrollView.contentInset = contentInsets
        self.scrollView.scrollIndicatorInsets = contentInsets
        var aRect = self.view.frame
        aRect.size.height -= keyboardSize.size.height
        if (!CGRectContainsPoint(aRect, activeField.frame.origin)) {
            self.scrollView.scrollRectToVisible(activeField.frame, animated: true)
        }
    }


}

func keyboardWillBeHidden(notification: NSNotification)
{
    let contentInsets = UIEdgeInsetsZero
    self.scrollView.contentInset = contentInsets
    self.scrollView.scrollIndicatorInsets = contentInsets
}

But how do I do it for a textView. I tried the same code with didBeginEditing of textView with no positive effect

Answer 1

One of the easy and no code of line solution is to use the following pods in your app.

IQKeyboardManger

Later you need to just import that in App Delegate and add this two lines of code in didfinishLaunching method:

  IQKeyboardManager.sharedManager().enable = true

Your problem will be solved for whole app.

For Swift 5:

IQKeyboardManager.shared.enable = true
