ios - 为自定义 View 不工作的 UIBarButtonItem 添加目标

Question

你好，

我在向 UIBarButtonItem 添加自定义操作时遇到问题
目标没有调用
有人看到问题了吗？

    let navBarMapImageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 22, height: 22))
    navBarMapImageView.contentMode = .scaleAspectFit
    navBarMapImageView.image = image
    navBarMapImageView.isUserInteractionEnabled = true
    navBarMapImageView.target(forAction: #selector(openMaps), withSender: self)
    let navBarMapButton = UIBarButtonItem(customView: navBarMapImageView)

感谢帮助

您正在将目标添加到 UIImageView，它不起作用，请检查下面的代码

    let btn1 = UIButton(type: .custom)
    btn1.setImage(UIImage(named: "imagename"), for: .normal)
    btn1.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
    btn1.addTarget(self, action: #selector(openMaps), for: .touchUpInside)
    let item1 = UIBarButtonItem(customView: btn1)

    self.navigationItem.setRightBarButtonItems([item1], animated: true)
