以编程方式使用带有 TabbarViewController 的 SWReavealController 创建幻灯片菜单 - swift

Question

我正在创建一个包含 TabBarViewController 的示例应用程序，我还使用 SWRevealViewController 实现了幻灯片菜单，但问题是它没有显示幻灯片菜单。

这里我设置rootViewController在appdelegate

 window = UIWindow(frame: UIScreen.main.bounds)

 window?.makeKeyAndVisible()

 window?.rootViewController = TabBarController()

这是我的 TabBarController，我实现了 2 个 tabBar 项，第一个 tabBar 项应该有滑动菜单

    let homeController = HomeController()
    let homeNavigation = UINavigationController(rootViewController: homeController)
    homeNavigation.tabBarItem.title = "Home"
    let menuController = MenuViewController()
    let swReveal = SWRevealViewController(rearViewController: homeNavigation, frontViewController: menuController)
    swReveal?.toggleAnimationType = SWRevealToggleAnimationType.easeOut
    swReveal?.toggleAnimationDuration = 0.30

    let favController = FavoriteController()
    let favNavigation = UINavigationController(rootViewController: favController)
    favNavigation.tabBarItem.title = "Favorite"
    viewControllers = [homeNavigation, favNavigation]

对于MenuController，我设置了一些用于显示菜单的导航按钮

    let menuButton = UIBarButtonItem(title: "Menu", style: .plain, target: self.revealViewController(), action: #selector(slideMenu))
    self.navigationItem.leftBarButtonItem = menuButton
@objc func slideMenu() {

    if revealViewController() != nil {
        revealViewController().revealToggle(animated: true)
        revealViewController().rearViewRevealWidth = (view.bounds.width * 80 ) / 100
    }
    else {
        print("no reveal view")
    }
}

您需要在 didFinishLaunchingWithOptions 方法中配置 SWRevealViewController，如下所示：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    let frontNavigationController:UINavigationController
    let rearNavigationController:UINavigationController
    let revealController = SWRevealViewController()
    var mainRevealController = SWRevealViewController()

    frontNavigationController =  UINavigationController(rootViewController: TabBarController())
    rearNavigationController = UINavigationController(rootViewController: MenuViewController())

    frontNavigationController.navigationBar.isHidden = true
    rearNavigationController.navigationBar.isHidden = true

    revealController.frontViewController = frontNavigationController
    revealController.rearViewController = rearNavigationController
    revealController.delegate = self
    mainRevealController  = revealController

    window = UIWindow(frame: UIScreen.main.bounds)
    self.window?.rootViewController = mainRevealController
    self.window?.makeKeyAndVisible()

    return true
}

并在您的 HomeController 中替换

let menuButton = UIBarButtonItem(title: "Menu", style: .plain, target: self.revealViewController(), action: #selector(slideMenu))

和

let menuButton = UIBarButtonItem(title: "Menu", style: .plain, target: self, action: #selector(slideMenu))

并删除

let menuController = MenuViewController()
let swReveal = SWRevealViewController(rearViewController: homeNavigation, frontViewController: menuController)
swReveal?.toggleAnimationType = SWRevealToggleAnimationType.easeOut
swReveal?.toggleAnimationDuration = 0.30

根据您的 TabBarController，您的最终代码将是：

func customTabbar (){

    let homeController = HomeController()
    let homeNavigation = UINavigationController(rootViewController: homeController)
    homeNavigation.tabBarItem.title = "Home"

    let favController = FavoriteController()
    let favNavigation = UINavigationController(rootViewController: favController)
    favNavigation.tabBarItem.title = "Favorite"

    let servicePhoneCollectionFLowLayoutInstance = UICollectionViewFlowLayout()
    let serviceTabbarFlowLayoutInit = ExploreController(collectionViewLayout: servicePhoneCollectionFLowLayoutInstance)

    let exploreController = serviceTabbarFlowLayoutInit
    let exploreNavigation = UINavigationController(rootViewController: exploreController)
    exploreNavigation.tabBarItem.title = "Explore"


    let moreController = DetailViewController()
    let moreViewController = UINavigationController(rootViewController: moreController)
    moreViewController.tabBarItem.title = "Tools"
    viewControllers = [homeNavigation, favNavigation, exploreNavigation, moreViewController]
}
