How to determine if a link was clicked inside a UITextView, Swift

I have implemented what I believe is a function from the UITextViewDelegate that is linked to the URLs used in the UITextView, however now the functions are called in my code.

This is the function I used from the delegate.

func textView(textView: UITextView!, shouldInteractWithURL URL: NSURL!, inRange characterRange: NSRange) -> Bool {

println("Link Selected!")

}

However, I used breakpoints and the code isn't even available at runtime? Is this the correct function or is there an alternative?

You need to make sure that the class that implements the delegate protocol is defined as a delegate for UITextView

.



self.textView.delegate = self

Your class might look something like this:

class MyClass: UITextViewDelegate {
     @IBoutet weak var aTextView: UITextView!

      override func viewDidLoad() {
                super.viewDidLoad()
                aTextView.delegate = self 
        }

       // Delegate
       func textView(textView: UITextView, shouldInteractWithURL URL: NSURL, inRange characterRange: NSRange) -> Bool {

                // User click on a link in a textview
                print("Link Selected!")

               // True => User can click on the URL Ling (otherwise return false)
                return true
       }


}
