ios - UIBarButtonItem(customView :)-不可点击

我在viewDidLoad中有以下内容。它设置自定义rightBarButtonItem（在自定义UINavigationBar中）。

    let button = UIButton()
    let attrs = [NSFontAttributeName: UIFont(name: "Montserrat-Light", size: 14)!, NSForegroundColorAttributeName: UIColor.black]
    let title = NSAttributedString(string: "Sign In", attributes: attrs)
    button.setAttributedTitle(title, for: .normal)
    button.addTarget(self, action: #selector(self.pushVcLogin), for: .touchUpInside)

    let parentView = UIView(frame: button.bounds)
    parentView.addSubview(button)
    button.sizeToFit()
    parentView.bounds = CGRect(x: 0, y: 0, width: button.bounds.size.width, height: button.bounds.size.height)

    self.navItem.rightBarButtonItem = UIBarButtonItem(customView: parentView)

定制的UIBarButtonItem看起来应该是这样，但它不可点击。
有什么想法吗？

最佳答案

首先，如果视图层次结构具有UINavigationController
其次，您可以使用navigationItem并在其上添加自定义的uibarbuttonem。
我刚刚检查了下面的代码，它就工作了。

    let button = UIButton()
    let attrs = [NSFontAttributeName: UIFont(name: "Montserrat-Light", size: 14)!, NSForegroundColorAttributeName: UIColor.black]
    let title = NSAttributedString(string: "Sign In", attributes: attrs)
    button.setAttributedTitle(title, for: .normal)
    button.addTarget(self, action: #selector(self.pushVcLogin), for: .touchUpInside)

    let parentView = UIView(frame: button.bounds)
    parentView.addSubview(button)
    button.sizeToFit()
    parentView.bounds = CGRect(x: 0, y: 0, width: button.bounds.size.width, height: button.bounds.size.height)

    self.navigationItem.rightBarButtonItem = UIBarButtonItem(customView: parentView)

这里还有一个故事板图像navigationController和viewController的样子。
