IOS 11 个启用了用户交互的导航项无法正常工作

Question

你好，我有一个导航项，其中有一个包含两个标签的视图，我已经为导航元素内的视图添加了 userInteractionEnabled（IBoutleted 作为 navigationView）

navigationView.isUserInteractionEnabled = true

mainTitleClicked = UITapGestureRecognizer(target: self, action: #selector(mainTitleTapped))

self.navigationView.addGestureRecognizer(mainTitleClicked)

这在 IOS 10 中有效，但是当我运行中的相同代码在 xcode 9 ios 11 UI 中被弄乱并且手势是没有得到认可

IOS 10 版本

IOS 11 版本

我应该改变什么才能让它在 ios 11

上工作

感谢您的帮助

我通过添加以下代码解决了它

if #available(iOS 11.0, *) {
        self.navigationController?.navigationBar.prefersLargeTitles = false
        self.navigationItem.largeTitleDisplayMode = .automatic
        var width = navigationView.sizeThatFits(CGSize(width: CGFloat.greatestFiniteMagnitude, height: CGFloat.greatestFiniteMagnitude)).width - 15.0
        let height = navigationView.sizeThatFits(CGSize(width: CGFloat.greatestFiniteMagnitude, height: CGFloat.greatestFiniteMagnitude)).height

        let screenSize: CGRect = UIScreen.main.bounds
        let windowWidth = screenSize.width
        width = windowWidth * 0.55

        let widthConstraint = navigationView.widthAnchor.constraint(equalToConstant: width)
        let heightConstraint = navigationView.heightAnchor.constraint(equalToConstant: height)

        heightConstraint.isActive = true
        widthConstraint.isActive = true
    }

激活高度和宽度约束是在另一个问题中给出的答案我目前没有 link 它会 post link 在编辑中（目前我我找不到那个问题）

我也有同样的问题，也用这段代码解决了：

if #available(iOS 11.0, *) {
            self.navigationController?.navigationBar.prefersLargeTitles = false
            self.navigationItem.largeTitleDisplayMode = .automatic
            var width = popUserChatView.sizeThatFits(CGSize(width: CGFloat.greatestFiniteMagnitude, height: CGFloat.greatestFiniteMagnitude)).width - 15.0
            let height = popUserChatView.sizeThatFits(CGSize(width: CGFloat.greatestFiniteMagnitude, height: CGFloat.greatestFiniteMagnitude)).height


            let screenSize: CGRect = UIScreen.main.bounds
            let windowWidth = screenSize.width
            width = windowWidth * 0.55

            let widthConstraint = popUserChatView.widthAnchor.constraint(equalToConstant: width)
            let heightConstraint = popUserChatView.heightAnchor.constraint(equalToConstant: height)

            heightConstraint.isActive = true
            widthConstraint.isActive = true
        }

调用 ViewDidLoad()
