尝试在 IOS 中创建滑动条菜单

Question

我想在我的应用程序中创建一个滑动条菜单（如下图所示）

当我点击那个汉堡包图标时，它应该会显示一个菜单，如下所示。

我目前正在使用 SWRevealController，这是一个用 Objective C 编写的库。我创建了一个桥接头并导入了该类。这是我目前的设置

我的初始视图分支到 Menu Controller 或 UIViewTable 是 SWRevealController，segue 是 SWRevealViewControllerSegueSetController 的子类。在我的 Food Item View Controller（存在汉堡导航的控制器）中，我添加了以下代码来激活滑动条操作。

override func viewDidLoad() {
        super.viewDidLoad()

        //Creating the slidebar Navigation using SWRevealViewController 
        if self.revealViewController() != nil {
            menuButton.target = self.revealViewController()
            menuButton.action = #selector(SWRevealViewController.revealToggle(_:))
            self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
        }

}

但是，当我单击按钮时，它仍然没有响应。当我使用我的其他应用程序执行此操作时，它运行良好。我不确定为什么它在这里不起作用

这是我用作参考的来源：http://www.appcoda.com/sidebar-menu-swift/

查看控制器完整代码

@IBOutlet weak var thumbnail_image: UIImageView!
    //@IBOutlet weak var food_detail: UITextView!
    @IBOutlet weak var testing: UILabel!

    @IBOutlet weak var menuButton: UIBarButtonItem!
    var jsonResponseFood: NSArray = NSArray() //API for types of food available
    var jsonResponseRecipe: NSArray = NSArray() // API for recipes in food
    var selectedFood: foodItem?
    var postStr: String?

    //Initializing API
    let FullRecipeAPIModel = fullRecipeAPIModel()

    override func viewDidLoad() {
        super.viewDidLoad()

        //Creating the slidebar Navigation using SWRevealViewController 
        if self.revealViewController() != nil {
            menuButton.target = self.revealViewController()
            menuButton.action = #selector(SWRevealViewController.revealToggle(_:))
            self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
        }


        print(selectedFood?.name as String!)
        //testing.text = self.selectedFood?.name

        let APIModel = apiModel()

        APIModel.delegate = self
        FullRecipeAPIModel.delegate = self
        APIModel.downloadItems(postString: postStr!)

        // Do any additional setup after loading the view.
    }

谢谢 StackOverflow。

您的代码中的问题是您没有将 SWRevealController 设置为根视图。明智的代码没有 Storyboard 选项可用，我们必须再次进行配置。这个库就是这样设计的。因此，如果您按以下方式更改代码，它将像魅力一样发挥作用。

if(stat == "login"){
                if(responseString == "invalid"){
                    self.isValid = false;
                    print(self.isValid)
                }

                DispatchQueue.main.async(execute: {
                    if self.checkLogin(data: responseString!) == true {
                        let storyboard = UIStoryboard(name: "food", bundle: nil)
                        let controller = storyboard.instantiateViewController(withIdentifier: "foodItemViewController") as! foodItemViewController
                        let navController = UINavigationController(rootViewController: controller) // Creating a navigation controller with VC1 at the root of the navigation stack.
                        let appDelegate = UIApplication.shared.delegate as! AppDelegate
                        let menuView :MenuController = storyboard.instantiateViewController(withIdentifier: "menuBar") as! MenuController
                        let revealController = SWRevealViewController()

                        revealController.frontViewController = navController;
                        revealController.rearViewController = menuView;

                        appDelegate.window?.rootViewController = revealController

                    }
                    else{
                        //Show alert here
                        self.showAlert(title: "User Does Not Exist", alertTitle: "Close", message: "");
                    }
                });
            }
            else{
                //CODE COULD BE SIMPLIFIED
                DispatchQueue.main.async(execute: {
                    if(responseString == "duplicate"){
                        //Show alert here
                        self.showAlert(title: "User with this email already exist", alertTitle: "Close", message: "Please register with another email address")
                    }
                    else{
                        //Show Food UITable
                        let storyboard = UIStoryboard(name: "food", bundle: nil)
                        let controller = storyboard.instantiateViewController(withIdentifier: "entranceFoodController") 
                        /*let navController = UINavigationController(rootViewController: controller) // Creating a navigation controller with VC1 at the root of the navigation stack.*/
                        let appDelegate = UIApplication.shared.delegate as! AppDelegate

                        let menuView :MenuController = storyboard.instantiateViewController(withIdentifier: "menuBar") as! MenuController
                        let revealController = SWRevealViewController()

                        revealController.frontViewController = controller;
                        revealController.rearViewController = menuView;

                        appDelegate.window?.rootViewController = revealController                    }

                });
            }

我今天也在做这个，这是使用 SWRevealController 的最佳选择吗，难道没有苹果内置的方法吗？我渴望看到选项，而不是从 Github 获得一些东西，除非那是我最后的手段。
