NSAttributedString click event in UILabel using swift

Question

Answer 1

You can add a tap gesture recognizer's to your label/view, or you can embed a link with a custom URL protocol into your attributed string, use a UITextView, and turn on link detection. You would then need to implement the UITextView delegate method for responding to links.

EDIT:

I have a demo project called DatesInSwift (link) on Github that implements clickable links in a UITextView. Take a look at the UITextView delegate method textView(_:shouldInteractWithURL:inRange) in ViewController.swift. That's the method that tells the text view that it should respond to the URL.

Then you have to implement a UIApplicationDelegate method to handle the URL. The sample app uses application(_:openURL:sourceApplication:annotation), which was deprecated in iOS 9. For new development you should use application(_:openURL:options:) instead.

You will also need to add a CFBundleURLTypes / CFBundleURLSchemes entry to your info.plist to register a custom URL scheme (like myompany.myapp.loginURL) in order for clicking on an embedded URL to invoke your app.
