How can I accurately detect if a link is clicked inside UILabels in Swift 4?

I managed to solve this myself by using a UITextView instead of a UILabel

Answer 1

For Dan Bray's solution above to work for me I had to call super.hitTest(point, with:event) instead of returning nil. Otherwise touchesBegan and touchesEnded were not invoked. I use the textViews inside a UIScrollView.

override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
    var location = point
    location.x -= self.textContainerInset.left
    location.y -= self.textContainerInset.top
    if location.x > 0 && location.y > 0 {


    let index = self.layoutManager.characterIndex(for: location, in: self.textContainer, fractionOfDistanceBetweenInsertionPoints: nil)
        for textLink in textLinks {
            let range = ((text ?? "") as NSString).range(of: textLink.0)
            if NSLocationInRange(index, range) {
                callback = {
                    self.linkDelegate?.didTap(text: textLink.0, withLink: textLink.1, inTextView: self)
                }
                return self
            }
        }
    }
    callback = nil
    return super.hitTest(point, with:event)
}
