ios - which UITextView is initiating textViewDidChange in Swift? -

i have number of uitextviews in viewcontroller. using textviewdidchange method handle user interaction:

func textviewdidchange(textview: uitextview) { //     } 

my question is, how determine textview initiating function, i.e. textview sender?

you can try simple technique.

func textviewdidchange(textview: uitextview) {    //textview(sender)    if(textview == yourtextview)    {      //do    }   }
