swift 3.0 let a href from html to call a swift function

Question

I have a html string come from the api service, for example :

<html><body><a href="testFunction" target = blank>link test</a>...</body></html>

Please note that I put the html string in UILabel and not in uiwebView

And in my ViewController.swift, I have a function :

func testFunction() {
  print("I am here")
}

What I need is how to call the function testFunction when the user click on the link test?

Thanks,

At first set this to the label:

label.isUserInteractionEnabled = true

Tapgesture:

let tap = UITapGestureRecognizer(target: self, action: 
#selector(self.testFunction(_:)))
self.label.addGestureRecognizer(tap)

Function:

func testFunction(_ sender: UITapGestureRecognizer) {
     print("I am here")
}

but what I have to do if for example I have two < a href> and for each one I have to show different data? – Houssam Hammoud Jun 06 '17 at 13:53
For the same label? – Gregga17 Jun 06 '17 at 13:57
Yes, what I need is when the user click on a I have to show a pop up with a detail of the word clicked. so maybe in some cases I have many – Houssam Hammoud Jun 06 '17 at 13:59
I think it is not possible – Gregga17 Jun 06 '17 at 14:06
so what I have to do in that case, do we have any method I can do it with, for example if I use a webview? – Houssam Hammoud Jun 06 '17 at 14:07
If you show it in a webview than the html works as normal – Gregga17 Jun 06 '17 at 14:09
@HoussamHammoud try to set link using attributed string with tags and on touch event check whether touch was within string of tag to handle action. Example : http://samwize.com/2016/03/04/how-to-create-multiple-tappable-links-in-a-uilabel/ – Pushpak Narasimhan Jun 06 '17 at 14:24

With NSSelectorFromString, you can call a method with a string.
