Create slide menu using SWReavealController with TabbarViewController programmatically - swift - ios

Question

I am creating a sample app which contains TabBarViewController and also i implement slide menu using SWRevealViewController and the problem is that the slide menu it not showing out.
Here i set rootViewController in appdelegate
window = UIWindow(frame: UIScreen.main.bounds)
window?.makeKeyAndVisible()
window?.rootViewController = TabBarController()
Here is my TabBarController which i implement 2 tabBar items which first tabBar item should have slide menu
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]
For MenuController i setup some navigation button for showing menu
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")
}
}

You need to configure SWRevealViewController in your didFinishLaunchingWithOptions method as shown below:
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
}
And in your HomeController replace
let menuButton = UIBarButtonItem(title: "Menu", style: .plain, target: self.revealViewController(), action: #selector(slideMenu))
with
let menuButton = UIBarButtonItem(title: "Menu", style: .plain, target: self, action: #selector(slideMenu))
And remove
let menuController = MenuViewController()
let swReveal = SWRevealViewController(rearViewController: homeNavigation, frontViewController: menuController)
swReveal?.toggleAnimationType = SWRevealToggleAnimationType.easeOut
swReveal?.toggleAnimationDuration = 0.30
From your TabBarController and your final code will be:
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]
}
