我正在开发一个应用程序,其中启动屏幕与 Twitter 类似,我想使用 MMDrawer 实现抽屉式导航,但出现错误: “UIViewControllerHierarchyInconsistency ',原因:'添加 Root View Controller 作为 View Controller 的子级:'”
我附上了AppDelegate代码 希望您能帮助我,非常感谢您阅读我的文章!问候。

最佳答案
您收到的错误非常清楚。
问题出在这里:
window?.rootViewController = drawerContainer
self.window?.rootViewController = mainPageNav
您正在设置rootViewController
,然后在下一行中使用不同的内容再次设置它。
然后,几行之后,您将执行以下操作:
drawerContainer = MMDrawerController(center: mainPageNav, leftDrawerViewController: leftSideMenuNav, rightDrawerViewController: rightSideMenuNav)
您正在获取窗口的rootViewController
,并尝试将其作为子级添加到另一个容器 View Controller 。
明显的修复:
删除此行:
self.window?.rootViewController = mainPageNav
更改
rootViewController
分配和drawerContainer
实例化的顺序。现在,您正在丢弃原始drawerContainer
的任何内容(如果它有值的话)。drawerContainer = MMDrawerController(center: mainPageNav, leftDrawerViewController: leftSideMenuNav, rightDrawerViewController: rightSideMenuNav)
需要先来
window?.rootViewController = drawerContainer
您的代码可能还有更多问题,但这两个肯定是问题。
