我有一个带有三个视图的TabView，这三个视图是启动应用程序时的主要视图。在某些视图中，我有NavigationLinks来打开DetailViews。当这些被关闭时，用户将返回到用户在打开NavigationLink之前最初所在的TabView中的视图。然而，从那时起，以编程方式设置TabView的选择变量就不起作用了。我有三个自定义按钮来作为替代左右滑动。
当按钮被按下时，TabView索引指示器会发生变化，所以我假设TabView已经在绑定变量中注册了变化，但是View不会发生变化。
在我的NavigationView上，我使用了一个自定义的后退按钮，这似乎是问题所在。当使用.navigationBarBackButtonHidden(true)时，问题发生了。否则它工作正常。
如何在使用自定义后退按钮时解决此问题？
