UITapGestureRecognizer无法在navigationBar titleView中的UIView上使用？

Question

I am trying to add tapGesture on navigationBar titleView but not getting any event. Please tell me how to resolve this issue.

 let titleView = UIView()
 titleView.frame = CGRect(x: 0, y: 0, width: 100, height: 60)
 titleView.backgroundColor = UIColor.yellow

 let profileImageView = UIImageView()
 profileImageView.contentMode = .scaleAspectFill
 profileImageView.layer.cornerRadius = 20
 profileImageView.clipsToBounds = true
 profileImageView.loadImageUsingCacheWithUrlString(urlString: user.image)
 titleView.addSubview(profileImageView)
 profileImageView.translatesAutoresizingMaskIntoConstraints = false
 profileImageView.leftAnchor.constraint(equalTo: titleView.leftAnchor).isActive = true
 profileImageView.centerYAnchor.constraint(equalTo: titleView.centerYAnchor).isActive = true
 profileImageView.widthAnchor.constraint(equalToConstant: 40).isActive = true
 profileImageView.heightAnchor.constraint(equalToConstant: 40).isActive = true

 let nameLabel = UILabel()
 nameLabel.text = user.name
 nameLabel.font = UIFont(name: "HelveticaNeue-Medium", size: 17)
 titleView.addSubview(nameLabel)
 nameLabel.translatesAutoresizingMaskIntoConstraints = false
 nameLabel.leftAnchor.constraint(equalTo: profileImageView.rightAnchor, constant: 8).isActive = true
 nameLabel.centerYAnchor.constraint(equalTo: profileImageView.centerYAnchor).isActive = true
 nameLabel.rightAnchor.constraint(equalTo: titleView.rightAnchor).isActive = true
 nameLabel.heightAnchor.constraint(equalTo: profileImageView.heightAnchor).isActive = true

 self.navigationItem.titleView = titleView
 titleView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(showChatTableViewController)))

Answer 1

Make sure to set isUserInteractionEnabled to true . By default it true but if it's not working in your case then try to set true

Make sure to debug your code and check that after adding titleView are you able to print out self.navigationItem.titleView ?

let titleView = UIView()
titleView.frame = CGRect(x: 0, y: 0, width: 100, height: 60)
titleView.backgroundColor = UIColor.yellow
titleView.isUserInteractionEnabled = true

self.navigationItem.titleView = titleView
titleView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(showChatTableViewController)))

@objc func showChatTableViewController() {
    print("tapped")
}
