Is there any way to make UITextFieldDelegate more dynamic in swift?

Question

I nearly have a UITextFieldDelegate in a UIViewController,and I make

import UIKit

class testViewController: UIViewController,UITextFieldDelegate{

    @IBOutlet weak var textName: UITextField!

    override func viewDidLoad(){
       super.viewDidLoad()

       textName.delegate = self
    }

    func textFieldShouldReturn(textField: UITextField) -> Bool {
       return true
    }
}

it works very well. but my question is, when i have two, or three UITextFields, and have different function,what should i do? Is there any way to make UITextFieldDelegate more dynamic in swift? just like java do? I remember that java may do like that:

textName.delegate = UITextFieldDelegate{
   func textFieldShouldReturn(textField: UITextField) -> Bool {
       return true
    }
}

textAddress.delegate = UITextFieldDelegate{
   func textFieldShouldReturn(textField: UITextField) -> Bool {
       return true
    }
}

The delegate methods take a parameter that identifies the text field for which the demarcate methods are being called. You can use this to provide different behaviours for different text fields.

now i'm using "tag" property to identify the text field – TzeChung Dec 09 '14 at 09:44
Don't use tags. Use a reference to the text field instead. Presumably you already have them as outlets. – Abizern Dec 09 '14 at 12:54
