How to set target and action for UIBarButtonItem at runtime

Question

Tried this but only works for UIButton:

[btn setTarget:self action:@selector(btnClicked:) forControlEvents:UIControlEventTouchUpInside];

Answer 1

For custom views: use an UITapGestureRecognizer and set up isUserInteractionEnabled to true.

    profileImageView.isUserInteractionEnabled = true

    let tap = UITapGestureRecognizer(target: self, action: #selector(handleProfileImageTap))
    profileImageView.addGestureRecognizer(tap)

    navigationItem.leftBarButtonItem = UIBarButtonItem(customView: profileImageView)
