MMDrawerController 未显示导航栏

Question

我是 swift 和 iOS 开发的新手。 在我的项目中，我正在使用 MMDrawerController 加载幻灯片菜单，它适用于幻灯片，但在 AppDelegate 中初始化 MMDrawerController 后，顶部导航栏 [导航控制器] 没有显示。评论 MMDrawer 初始化显示导航栏和点击事件正在正常触发，以下是导航初始化代码，

func buildNavigationDrawer()
    {

            // Instantiate Main.storyboard
            let mainStoryBoard:UIStoryboard = UIStoryboard(name:"Main", bundle:nil)

            // Create View Controllers
            let mainPage:TabBarViewController = mainStoryBoard.instantiateViewControllerWithIdentifier("TabBarViewController") as! TabBarViewController

            let leftSideMenu:LeftSideViewController = mainStoryBoard.instantiateViewControllerWithIdentifier("LeftSideViewController") as! LeftSideViewController

            let rightSideMenu:RightSideViewController = mainStoryBoard.instantiateViewControllerWithIdentifier("RightSideViewController") as! RightSideViewController



            // Wrap into Navigation controllers
            let leftSideMenuNav = UINavigationController(rootViewController:leftSideMenu)
            let rightSideMenuNav = UINavigationController(rootViewController:rightSideMenu)

            // Cerate MMDrawerController
            drawerContainer = MMDrawerController(centerViewController: mainPage, leftDrawerViewController: leftSideMenuNav, rightDrawerViewController: rightSideMenuNav)

            drawerContainer!.openDrawerGestureModeMask = MMOpenDrawerGestureMode.PanningCenterView
            drawerContainer!.closeDrawerGestureModeMask = MMCloseDrawerGestureMode.PanningCenterView

            // Assign MMDrawerController to our window's root ViewController
            window?.rootViewController = drawerContainer

    }

在有关MMDrawerController 的示例之一中，有以下代码：

 self.drawerController = [[MMDrawerController alloc]
                     initWithCenterViewController:navigationController....

尝试将您的mainPage 更改为UINavigationController，并将rootViewController 链接到TabBarViewController，您应该可以解决问题。

详情：

// Wrap into Navigation controllers
            let leftSideMenuNav = UINavigationController(rootViewController:leftSideMenu)
            let rightSideMenuNav = UINavigationController(rootViewController:rightSideMenu)
            let centerMenuNav = UINavigationController(rootViewController: mainPage)

            // Cerate MMDrawerController
            drawerContainer = MMDrawerController(centerViewController: centerMenuNav, leftDrawerViewController: leftSideMenuNav, rightDrawerViewController: rightSideMenuNav)
