In my app when the user logs in, they should be taken to a welcome screen, which is part of a TabBarController. But for some reason, when I run the following lines, the welcome screen (HomeScreenViewController) shows up without the TabBar navigation buttons at the bottom.
let homeViewController = self.storyboard?.instantiateViewController(identifier: Constants.Storyboard.homeViewController) as? HomeScreenViewController
self.view.window?.rootViewController = homeViewController
self.view.window?.makeKeyAndVisible()
Inspired by another StackOverflow post, I tried this, but it didn't work either:
let homeController = self.storyboard?.instantiateViewController(identifier:Constants.Storyboard.homeViewController)
(TabBarController.currentInstance?.selectedViewController as?UINavigationController)?.pushViewController(homeController!, animated: true)
For reference, the name of my UITabBarController class is TabBarController and the identifier can be accessed via
Constants.Storyboard.tabBarCont
Thanks!
I think you can try this..
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
window = UIWindow(frame: UIScreen.main.bounds)
let tabBarController = UITabBarController()
let homeViewController = self.storyboard?.instantiateViewController(identifier: Constants.Storyboard.homeViewController) as? HomeScreenViewController
let anyOtherViewController = self.storyboard?.instantiateViewController(identifier: anyOtherViewController) as? AnyOtherViewController
homeViewController.tabBarItem = UITabBarItem(title: "Home", image: UIImage(named: "home_image"),tag: 1)
anyOtherViewController.tabBarItem = UITabBarItem(title: "Other",image:UIImage(named: "other") ,tag:2)
tabBarController.viewControllers = [homeViewController, anyOtherViewController]
window?.rootViewController = tabBarController
window?.makeKeyAndVisible()
return true
}
Use like this after login:
let storyboard : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let centerViewController = storyboard.instantiateViewController(withIdentifier: "tabbar") as! TabBarController
centerViewController.selectedIndex = 0
centerViewController.modalPresentationStyle = UIModalPresentationStyle.fullScreen
let appDelegate = UIApplication.shared.delegate as! AppDelegate
if let window = UIApplication.shared.windows.first {
appDelegate.window = window
}
appDelegate.window!.rootViewController = centerViewController
self.present(centerViewController!, animated: false, completion: nil)

so i have this storyboard and i want the user to be shown the login view controller if he is not logged in or the tab view controller otherwise.
this is my code inside the app delegate :
`
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FirebaseApp.configure()
UITabBar.appearance().tintColor = .white
// check user
let authListener = Auth.auth().addStateDidChangeListener { auth, user in
if user != nil {
print("USER IS NOT NIL")
userService.observeUserProfile(uid: user!.uid) { userProfile in
userService.currentUserProfile = userProfile
}
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "TabBarVC") as! UITabBarController
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = vc
self.window?.makeKeyAndVisible()
} else {
print("USER IS NIL")
userService.currentUserProfile = nil
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "FirstVC") as! UIViewController
vc.modalPresentationStyle = .fullScreen
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = vc
self.window?.makeKeyAndVisible()
}
}
}
`
My problem is that if the user is not logged it looks like this:
As you can see the view is not full screen even though i specified that in the app delegate so the user can simply dismiss it and enter the main screen. Also in the tab view controller i have the main screen with a playing video and the login screen also has a playing video in the background and both videos are played at the same time XD .Any tips would be welcome.
change storyboard--> viewcontroller---> attribute inspector---> change presentation from Automatic to Full Screen
let nav = UINavigationController()
nav.navigationBar.isHidden = true
//your Controller
let first = Router.shared.splashVC()
let third = Router.shared.CustomTabbarVC()
third.selectedIndex = 0
//add multiple controller in array
nav.viewControllers = [first,third]
UIApplication.shared.keyWindow?.rootViewController = nav
UIApplication.shared.keyWindow?.makeKeyAndVisible()
First Select all ViewController and change presentation mode Automatic from Full Screen in Simulated Metrics.
Added UINavigationController in rootViewController
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "TabBarVC") as! UITabBarController
let navigationController = UINavigationController(rootViewController: vc)
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = navigationController
vc.navigationController?.isNavigationBarHidden = true
self.window?.makeKeyAndVisible()
I have included kukushi side menu. I have done things according to the documentation. The screen shot with the codes in app delegate are below:
func setUpHomeVC() {
var window: UIWindow?
let storyBoard = UIStoryboard.init(name: "Dashboard", bundle: Bundle.main)
let contentViewController = storyBoard.instantiateViewController(withIdentifier: "DashboardViewController") as! DashboardViewController
let menuViewController = storyBoard.instantiateViewController(withIdentifier: "MenuViewCOntroller") as! MenuViewCOntroller
SideMenuController.preferences.basic.menuWidth = 240
SideMenuController.preferences.basic.statusBarBehavior = .hideOnMenu
SideMenuController.preferences.basic.position = .sideBySide
SideMenuController.preferences.basic.direction = .left
SideMenuController.preferences.basic.enablePanGesture = true
SideMenuController.preferences.basic.supportedOrientations = .portrait
SideMenuController.preferences.basic.shouldRespectLanguageDirection = true
window = UIWindow(frame: UIScreen.main.bounds)
window?.rootViewController = SideMenuController(contentViewController: contentViewController,
menuViewController: menuViewController)
window?.makeKeyAndVisible()
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
setUpHomeVC()
return true
}
The identifier, class and module has been added according to the documentation. After login there is dashboard which consist of menu button. On login the code is:
private func goToDashboard() {
let dashboard = UIStoryboard(name: "Dashboard", bundle: nil)
let navView = dashboard.instantiateViewController(identifier: "DashboardViewController") as DashboardViewController
present(navView,animated: false)
}
On dashboard there is a button which have click event:
#IBAction func btnMenuClicked(_ sender: Any) {
print("Menu button has been clicked")
self.sideMenuController?.revealMenu(animated: true)
}
when I click on that button the print function is called but the menu is not revealed.
Can anyone explain it. Thanks in advance.
You can setup your appDelegate like this,
func setUpHomeVC() {
let storyboard = UIStoryboard(name: "Your Login Storyboard", bundle: nil)
let initialViewController = storyboard.instantiateViewController(withIdentifier: "LoginVC")
self.window?.rootViewController = initialViewController
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
setUpHomeVC()
return true
}
And in your login event:
private func goToDashboard() {
self.pushVC()
}
private func pushVC() {
let storyBoard = UIStoryboard.init(name: "Dashboard", bundle: Bundle.main)
let contentViewController = storyBoard.instantiateViewController(withIdentifier: "DashboardViewController") as! DashboardViewController
let menuViewController = storyBoard.instantiateViewController(withIdentifier: "MenuViewCOntroller") as! MenuViewCOntroller
SideMenuController.preferences.basic.menuWidth = 240
SideMenuController.preferences.basic.statusBarBehavior = .hideOnMenu
SideMenuController.preferences.basic.position = .sideBySide
SideMenuController.preferences.basic.direction = .left
SideMenuController.preferences.basic.enablePanGesture = true
SideMenuController.preferences.basic.supportedOrientations = .portrait
SideMenuController.preferences.basic.shouldRespectLanguageDirection = true
window = UIWindow(frame: UIScreen.main.bounds)
window?.rootViewController = SideMenuController(contentViewController: contentViewController,
menuViewController: menuViewController)
window?.makeKeyAndVisible()
}
Your DashboardVC should be in a navigation controller for sidemenu to present. Try pushing the controller instead of presenting it.If you have the controller in a different storyboard, you can use this function:
func pushVC(storyboardName : String, vcname : String) {
let vc = UIStoryboard.init(name: storyboardName, bundle: Bundle.main).instantiateViewController(withIdentifier: vcname)
self.navigationController?.pushViewController(vc, animated: true)
}
Also, I would suggest you learn about when to push, present, and make root view controllers as all serve different purposes.
I think your current implementation is wrong. The problem is we need to implement and push the view controllers as SideMenuControllers bundle, not separate ViewControlers
If you want to have the side menu after login, then set your login page first in your didFinishLaunchingWithOptions.
Then you can call setUpHomeVC from your loginVC.
I am using SWRevealViewController for side menu functionality. Its working fine but whenever I have added the following code in didFinishLaunchingWithOptions method. side menu is not working for first time launch.
How to solve this problem??
this is my Code :
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// UserDefaults.standard.synchronize()
// IQKeyboardManager.sharedManager().enable = true
self.window = UIWindow(frame: UIScreen.main.bounds)
guard UserDefaults.standard.object(forKey: "IsFirstTime") != nil else {
UserDefaults.standard.set(true, forKey: "IsFirstTime")
self.window = UIWindow(frame: UIScreen.main.bounds)
let storyboard = UIStoryboard.init(name: "Main", bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "LaunchViewController") as! LaunchViewController
let navigationController = UINavigationController.init(rootViewController: viewController)
self.window?.rootViewController = navigationController
self.window?.makeKeyAndVisible()
return true
}
self.window = UIWindow(frame: UIScreen.main.bounds)
let storyboard = UIStoryboard.init(name: "Main", bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "SWRevealViewController") as! SWRevealViewController
// let navigationController = UINavigationController.init(rootViewController: viewController)
self.window?.rootViewController = viewController
self.window?.makeKeyAndVisible()
return true
}
Thank you
Here you are making LaunchViewController initial VC on first launch. That's why it is not working at first time.
To use SWRevealViewController you need two view controller, one is front view controller which you want to show first time and second is for drawer which maybe tableViewController that contains all other view controller. To add SWRevealViewController call openDrawer() in AppDelegate.
func openDrawer() {
let storyboard = UIStoryboard(name: "Main", bundle: Bundle.main)
let drawerVC = storyboard.instantiateViewController(withIdentifier: "idDrawerVC") as! RearVC
let dashboardVC = storyboard.instantiateViewController(withIdentifier: "idFrontVC") as! FrontVC
let frontNavigationController = UINavigationController(rootViewController: dashboardVC)
let revealViewController = SWRevealViewController(rearViewController: drawerVC, frontViewController: frontNavigationController)
revealViewController?.delegate = self
revealViewController?.view.backgroundColor = .clear
revealViewController?.modalTransitionStyle = .crossDissolve
window?.rootViewController = revealViewController
}
I was wondering what is the best practice to implement login screen for Master-Detail application which has SplitView Controller as a root controller. I am using the appDelegate to display the login screen if the user is not logged in. However, when I want to dismiss the loginVC the app goes into blank Detail page instead of the MasterController. Would be a modal login screen better option for Master-Detail app?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let loginVC = storyboard.instantiateViewControllerWithIdentifier("LoginVC") as! loginViewController
self.window?.rootViewController = loginVC
return true
let splitViewController = self.window!.rootViewController as! UISplitViewController
let navigationController = splitViewController.viewControllers[splitViewController.viewControllers.count-1] as! UINavigationController
navigationController.topViewController!.navigationItem.leftBarButtonItem = splitViewController.displayModeButtonItem()
splitViewController.delegate = self
return true
And then in my loginVC:
#IBAction func goHome(sender: AnyObject) {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let splitViewController = storyboard.instantiateViewControllerWithIdentifier("SplitViewControllerID") as! UISplitViewController
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.window?.rootViewController = splitViewController
}
By changing the code of goHome function it works for me. Below is the code:
#IBAction func goHome(sender: AnyObject) {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let splitViewController = storyboard.instantiateViewController(withIdentifier: "SplitViewControllerID") as! UISplitViewController
let appDelegate = UIApplication.shared.delegate as! AppDelegate
appDelegate.window?.rootViewController = splitViewController
splitViewController.preferredDisplayMode = .allVisible
let navigationController = splitViewController.viewControllers[splitViewController.viewControllers.count-1] as! UINavigationController
navigationController.topViewController!.navigationItem.leftBarButtonItem = splitViewController.displayModeButtonItem
}
My onboarding process (login/signup) lives outside of the UINavigationController chain, but when the login is authenticated I call a method in the appdelegate thats supposed to instantiate the rootViewController and then push to it. I've tried two things:
The snippet above worked in appDelegate from a method that gets called when a local notification is responded to, but not in this case.
self.window?.makeKeyAndVisible()
self.window?.rootViewController?.navigationController?.popToRootViewControllerAnimated(true)
And heres another method I tried:
let rootViewController = self.window?.rootViewController
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let dashboard = mainStoryboard.instantiateViewControllerWithIdentifier("DashboardViewController") as! DashboardViewController
rootViewController!.navigationController?.popToViewController(dashboard, animated: true)
Neither of these work. What am I doing wrong?
My login view controller also live outside of my tab bar controller so this is what I did:
In the appDelegate:
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let loginVC = storyboard.instantiateViewControllerWithIdentifier("LoginVC") as! LoginViewController
self.window?.rootViewController = loginVC
self.window!.makeKeyAndVisible()
return true
}
then I have a method in my loginViewContoller.swift:
#IBAction func loginPushed(sender: AnyObject) {
//other stuff here
let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)
let tabBarController = UITabBarController()
let first = mainStoryBoard.instantiateViewControllerWithIdentifier("firstNavController") as! UINavigationController
let second = mainStoryBoard.instantiateViewControllerWithIdentifier("secondNavController") as! UINavigationController
let third = mainStoryBoard.instantiateViewControllerWithIdentifier("thirdNavController") as! UINavigationController
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
let controllers = [first, second, third]
tabBarController.viewControllers = controllers
appDelegate.window!.rootViewController = tabBarController
appDelegate.window!.makeKeyAndVisible()
}
I think you shouldn't call the 'popToRootViewController', you can reassignment the window.rootViewController~
