没有故事板的Swift SWRevealController

Question

我用故事板实现了SWRevealController，一切都很好，但现在我想在没有故事板的情况下编写应用程序。

有人可以帮我实施吗？我有一个FrontViewController和一个MenuViewController。我是否需要一个额外的SWRevealViewController，如果是的话，我需要编写什么代码？

我知道SWRevealController上有一些信息，但它在Objective-C中，我在Swift 2.0中写这个有一些问题。

您可以按照以下方式执行此操作。

在appDelegate中创建一个函数createSlidingMenu。

func createSlidingMenu(){

        let frontViewController = //create instance of frontVC
        let rearViewController  = //create instance of rearVC(menuVC)


        //create instance of swRevealVC based on front and rear VC
        let swRevealVC = SWRevealViewController(rearViewController: rearViewController, frontViewController: frontViewController);
        swRevealVC.toggleAnimationType = SWRevealToggleAnimationType.EaseOut;
        swRevealVC.toggleAnimationDuration = 0.30;

        //set swRevealVC as rootVC of windows
        self.window?.rootViewController = swRevealVC!;
}

在createSlidingMenu中致电application:didFinishLaunchingWithOptions:，您就可以了。

这对我有用（在快速3.1中）

1. 在StoryBoard中创建MasterViewController，HomeViewController（嵌入在UINavigationController中）与storyboardId＆＃34; HomeViewController＆＃34;和MenuViewController（嵌入在UINavigationController中）与storyboardId＆＃34; MenuViewController＆＃34;。 < / LI>

2. 在Storyboard中创建MasterViewController类并关联到UIViewController（MasterViewController）并实现SWRevealViewControllerDelegate协议（参见代码）

   import UIKit
   
   class MasterViewController: UIViewController, SWRevealViewControllerDelegate {
   
   override func viewDidLoad() {
       super.viewDidLoad()
   
       let frontNavigationController:UINavigationController
       let rearNavigationController:UINavigationController
       let revealController = SWRevealViewController()
       var mainRevealController = SWRevealViewController()
   
       let menuTable = self.storyboard?.instantiateViewController(withIdentifier:  "MenuViewController")as! MenuViewController
       let homepage = self.storyboard?.instantiateViewController(withIdentifier: "HomeViewController") as! HomeViewController
   
       frontNavigationController =  UINavigationController(rootViewController: homepage)
       rearNavigationController =  UINavigationController(rootViewController: menuTable)
       rearNavigationController.setNavigationBarHidden(true, animated: false)
   
       revealController.frontViewController = frontNavigationController
       revealController.rearViewController = rearNavigationController
       revealController.delegate = self
       mainRevealController  = revealController
   
       UIApplication.shared.delegate!.window?.rootViewController = mainRevealController
   }
   

   }

3. 作为替代，您可以省略MasterViewController并：

   • 在AppDelegate和
   中实现SWRevealViewControllerDelegate
   • 复制上面在应用程序中写的viewDidLoad body的代码：didFinishLaunchingWithOptions：

除了Hitendra之外，我还修改了以下代码，以便我可以在Home中进行导航

AppDelegate.swift

func toHome() {
    let frontViewController = HomeController()//create instance of frontVC
    let rearViewController  = MenuController() //create instance of rearVC(menuVC)

    let swRevealVC = SWRevealViewController(rearViewController: rearViewController, frontViewController: frontViewController);
    swRevealVC?.toggleAnimationType = SWRevealToggleAnimationType.easeOut;
    swRevealVC?.toggleAnimationDuration = 0.30;

    navigationController = UINavigationController(rootViewController: swRevealVC!)
    self.window?.rootViewController = navigationController
}

LoginController.swift，当用户点击登录按钮

时

@objc private func login() {
     let appDelegate = UIApplication.shared.delegate as! AppDelegate
     appDelegate.toHome()
     return
}

HomeController.swift

override func viewDidLoad() {
    super.viewDidLoad()

    setupLayout() // layout programmatically, I didn't put code here

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

}

@objc private func menu() {
    revealViewController().revealToggle(self)
}
