Swift 2.1-将信息输入到同时填充Textfield的TextView中吗？

Question

I am currently using a framework called "Swift Validator", it only allows for textfields to be used. In my case I need a textView, my question is how do I input information that I type into the textview which then populates a textfield in the background at the same time? as well as when removing inputed text?

Answer 1

Use the UITextViewDelegate method textViewDidChange to listen for changes to the Text View. When the method is called, update the Text Field. Here's an example:

func textViewDidChange(theTextView: UITextView) {
    self.textField.text = theTextView.text   
}

Don't forget to extend UITextViewDelegate and to set the Text View's delegate to self .
