获取正在键入的最后一个单词

Question

I want to get the word that is currently being typed in a UITextField.

Case 1:

hello there

If the cursor is after the second e (meaning e has just been typed, then the word there should be returned

Case 2:

User deletes o from hello (cursor is after the second l ), then the word hell should be returned

I have some code for this but it is returning all text in the UITextField.

postView.textView.delegate = self

func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
    let text = (textView.text as NSString?)?.replacingCharacters(in: range, with: text)

    return true
}

Update 1: I have gone through these similar questions but these didn't work for me.

Get currently typed word in UITextView

Get word that is being typed

Answer 1

Try with below code, its working at my end.

func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
    let nsString = textView.text as NSString?
    let newString = nsString?.replacingCharacters(in: range, with: text)
    let arr = newString?.components(separatedBy: " ")
    self.lblWord.text = arr?.last
    return true
}
