启用了用户交互的IOS 11导航项无法正常工作

Question

嗨我有导航项目有一个视图，其中包含两个标签我为导航元素内部的视图添加了userInteractionEnabled（IBoutleted as navigationView）

navigationView.isUserInteractionEnabled = true

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

self.navigationView.addGestureRecognizer(mainTitleClicked)

这在IOS 10中运行但是当我在xcode 9中运行相同的代码时ios 11用户界面搞砸了，手势无法识别

IOS 10版

IOS 11版

我应该更改什么才能使其在ios 11上运行

感谢您的帮助

我解决了它添加以下代码

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
    }

使高度和宽度约束处于活动状态是另一个问题的答案我目前没有链接到它将在编辑中发布链接（目前我无法找到该问题）

我遇到同样的问题并且也使用此代码解决了：

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
        }

在ViewDidLoad（）中调用
