Swift 没有故事板的 SWRevealController

Question

我用故事板实现了 SWRevealController 并且一切正常，但现在我想在没有故事板的情况下编写应用程序。

有人可以帮我实现吗？我有一个 FrontViewController 和一个 MenuViewController。为此，我是否需要一个额外的 SWRevealViewController？如果需要，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.

中写这个时遇到一些问题

Answer 1

您可以按照下面的方式进行。

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 application:didFinishLaunchingWithOptions: 中致电 createSlidingMenu，一切顺利。

这对我有用（在 swift 3.1 中）

在 StoryBoard 中创建 MasterViewController、HomeViewController（嵌入在 UINavigationController 中）和 storyboardId "HomeViewController"，以及 MenuViewController（嵌入在 UINavigationController 中）和 storyboardId "MenuViewController"。

创建 MasterViewController class 并关联到 Storyboard 中的 UIViewController (MasterViewController) 并实现 SWRevealViewControllerDelegate 协议（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
}

}

作为替代方案，您可以省略 MasterViewController 并且：
- 在 AppDelegate 中实现 SWRevealViewControllerDelegate 和
- 复制上面application:didFinishLaunchingWithOptions中写的viewDidLoad body的代码:

除了Hitendra，我修改了下面的代码，这样我就可以把导航放到首页了

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)
}
