.addTarget method to add an action to a UITextView

Question

I have a function which detects change in a UITextView and changes the colour of a few words while the user is editing. Well, to link this function to a UITextField I can simply call the .addTarget method. But this does not work for the UITextView . I wanted to ask how I should connect the UITextView to the function. Thanks in advance.

Answer 1

Basically add "UITextViewDelegate" and do this

override func viewDidLoad() {
    yourTextView.delegate = self

}


func textViewDidChange(textView: UITextView) {
    //Whatever your code is
}
