我是 swift 和 iOS 开发的新手。 在我的项目中，我使用 MMDrawerController 加载幻灯片菜单，它对于幻灯片工作正常，但是在 AppDelegate 中初始化 MMDrawerController 后，顶部导航栏 [导航 Controller ] 没有显示。注释MMDrawer初始化显示导航栏和点击事件正在正确触发，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
}
最佳答案
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。
详细信息:
// 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)
