敲击UITextField时如何停止显示键盘？

Question

//Xcode 8.3.3 | Swift 3

Disclaimer: Alright, so there are some Q&A on SO that answer this question. However, after extensive Googling, I was not able to find any that are up-to date in Swift (they're all in Objective C and date back to 2010, etc).

I have a project in which I need the user to be able to tap a UITextField and for the blinking line to come up, but I already have a number pad implemented with UIButtons. This means that I do not want the default or any keyboard to come up when the text field is pressed.

What is the easiest way to achieve this currently?

Answer 1

You can do like this -

YourTextView.inputView = UIView()
YourTextView.inputAccessoryView = UIView() 

this will not open the keyboard but allow cursor blink.

Answer 2

try do this:

extension YourController: UITextFieldDelegate {

    func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
        // do some things

        NotificationCenter.default.addObserver(self, selector: #selector(keyboardHidden), 
        name: NSNotification.Name.UIKeyboardWillShow, object: nil)
        return false
    }

    @objc private func keyboardHidden() {
        // disabled keyboard 
        yourTextField.resignFirstResponder()
    }
}

Answer 3

The answer linked by @paulvs translated to Swift 3 would be:

let tempView = UIView(frame: .zero)
yourTextField.inputView = tempView
