没有情节提要的Swift SWRevealController

Question

I implemented SWRevealController with storyboard and everything works great, but now I would like to program the app without storyboard.

Can someone help me with the implementation? I have a FrontViewController and a MenuViewController. Do I need an extra SWRevealViewController for this and if yes, what do I have to code?

I know there is some information on SWRevealController but it is in Objective-C and I have some problems to write this in Swift 2.0.

Answer 1

You can do it as follow.

Create one function createSlidingMenu in appDelegate.

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!;
}

call createSlidingMenu in application:didFinishLaunchingWithOptions: and you are good to go.

This worked for me (in swift 3.1)

1. In the StoryBoard create MasterViewController, HomeViewController (embedded in UINavigationController) with storyboardId "HomeViewController", and MenuViewController (embedded in UINavigationController) with storyboardId "MenuViewController".

2. Create MasterViewController class and associate to UIViewController (MasterViewController) in Storyboard and implements SWRevealViewControllerDelegate protocol (see code)

    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. As alternative you could omit MasterViewController and:

   • implement SWRevealViewControllerDelegate in AppDelegate and
   • copy the code of viewDidLoad body wrote above in application:didFinishLaunchingWithOptions:

In addition to Hitendra, I modify the following code so I can put navigation in Home

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, when user click login button

@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)
}
