如何知道何时点击 WKWebView 中的 TextField

Question

In this Apple doc about Keyboards , the first sentence says:

When users touch a text field, a text view, or a field in a web view , the system displays a keyboard.

Are there any methods or KVO observers to know when a user starts/stops typing in a field in WKWebView ?

For example, when interacting with a regular UITextField, if I want to know when a user starts and stops typing, these two methods are available, but WKWebView doesn't have anything like these

func textFieldDidBeginEditing(_ textField: UITextField) {
}

func textFieldDidEndEditing(_ textField: UITextField) {

}

I don't need the keyboardWillShow/Hide notifications. I need some delegate methods or a KVO for the textFields specific to WKWebView .

Answer 1

Unfortunately WKWebView does't have delegate methods that gets called when web form inputs are triggered.
