UITapGestureRecognizer working on UIImageView but not on UILabel

Question

I have a UITableViewCell class named CommentsTableViewCell which among other things includes a UIImageView and a UILabel.

Code I'm using:

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(CommentsTableViewCell.showUserViewController))
nameLabel.userInteractionEnabled = true
avatarRoundImageView.userInteractionEnabled = true
nameLabel.addGestureRecognizer(tapGesture)
avatarRoundImageView.addGestureRecognizer(tapGesture)

As you can understand I have a function which shows another UIViewController whenever the UIImageView or the UILabel is tapped.

What buffles me is that the tapGesture works correctly on the UIImageView but not on the UILabel.

Any ideas?

Answer 1

You need different gesture for all control

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(CommentsTableViewCell.showUserViewController))
avatarRoundImageView.userInteractionEnabled = true
avatarRoundImageView.addGestureRecognizer(tapGesture)

let tapGesture2 = UITapGestureRecognizer(target: self, action: #selector(CommentsTableViewCell.showUserViewController))
nameLabel.userInteractionEnabled = true
nameLabel.addGestureRecognizer(tapGesture2)

Answer 2

You need to create two UITapGestureRecognizer object because UITapGestureRecognizer works with single UI element object. So create second TapGestureRecognizer and assign one to UILabel and one to UIImageView.

From UIGestureRecognizer documentation.

A gesture recognizer operates on touches hit-tested to a specific view and all of that view’s subviews. It thus must be associated with that view. To make that association you must call the UIView method addGestureRecognizer(_:). A gesture recognizer doesn’t participate in the view’s responder chain.
