导航栏没有用MMDrawerController显示

Question

我对快速和iOS的发展很陌生。在我的项目中，我用MMDrawerController加载幻灯片菜单，它对幻灯片很好，但是在AppDelegate中初始化MMDrawerController之后，通过顶部导航条导航控制器就不会显示出来。注释MMDrawer初始化显示导航栏和单击事件是正确的，下面是导航初始化代码，

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的一个示例中，有以下代码：

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

尝试用一个链接到mainPage的UINavigationController来改变您的rootViewController，您应该可以解决这个问题。

// 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)
