I have two view controller in the TabBar. I set up like if user is logged in then it's directly show the TabBar else it's showing loginViewController. Look the Code in AppDelegate
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UserDefaults.standard.register(defaults: ["NSApplicationCrashOnExceptions": true])
let status = UserDefaults.standard.bool(forKey: "status")
//StoryBoard Decide
if (status == false){
let storyBoard : UIStoryboard = UIStoryboard(name: "Tools", bundle:nil)
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "LoginViewController") as! LoginViewController
let navigationController = UINavigationController(rootViewController: nextViewController)
let appdelegate = UIApplication.shared.delegate as! AppDelegate
appdelegate.window!.rootViewController = navigationController
}else {
let storyBoard : UIStoryboard = UIStoryboard(name: "Tools", bundle:nil)
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "tabbar") as! UITabBarController
let navigationController = UINavigationController(rootViewController: nextViewController)
let appdelegate = UIApplication.shared.delegate as! AppDelegate
appdelegate.window!.rootViewController = navigationController
}}
But when it's work proper when i go through login ViewController but when user is alredy logged in it's showing the navigation bar in the HomeViewController.
This is my storyBoard Setup.
And also how to manage the Navigation with TabBar.
Because you are making new navigation controller then add tabbar as its root view.
Instead of making UINavigationController you can do this:
Replace
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "tabbar") as! UITabBarController
let navigationController = UINavigationController(rootViewController: nextViewController)
let appdelegate = UIApplication.shared.delegate as! AppDelegate
appdelegate.window!.rootViewController = navigationController
with:
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "tabbar") as! UITabBarController
self.window?.rootViewController = nextViewController
self.window?.makeKeyAndVisible()

I have two storyboards, one which contains everything the app really is, and another which contains an "onboarding"/tutorial to my app.
Once the tutorial is done, I want to navigate back to my original view controller.
This is my code to navigate to the other storyboard:
let defaults = UserDefaults.standard
if defaults.bool(forKey: "firstOpened") {
print("First VC launched")
}else{
var vc: UIViewController
let goTo = UIStoryboard(name: "Onboarding", bundle: nil).instantiateViewController(withIdentifier: "notificationStoryboard") as! FirstOnboardingViewController
self.present(goTo, animated: true, completion: nil)
}
With this, it works, except the TabBarController is not showing, and not working the way I want it to.
And this is my code to navigate back to the Main.Storyboard:
#objc func handleSecondPush() {
//registerForRemoteNotifications()
UserDefaults.standard.set(true, forKey: "firstOpened")
let goTo = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "pushToFeedVC")
self.present(goTo, animated: true, completion: nil)
//self.performSegue(withIdentifier: "goToLink", sender: nil)
}
I have also tried this in the other Storyboard, but with this the button doesn't change the view:
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "MainTabBarController") as! UITabBarController
print(controller)
self.window?.rootViewController = controller
self.window?.makeKeyAndVisible()
if let tabBarVc = self.window?.rootViewController as? UITabBarController {
tabBarVc.selectedIndex = 1
}
Question in short terms: So my question is, how can I navigate back to the main.storyboard which will contain the TabBarController with a selected index of 1, from a storyboard that doesn't contain navigation controller or a TabBarController?
When you present the onbaording you should return back to the tab with with
self.dismiss(animated:true,completion:nil)
for complex presentations you can do this for easy re-back
let vc = storyboard.instantiateViewController(withIdentifier: "MainTabBarController") as! UITabBarController
(UIApplication.shared.delegate as! AppDelegate).window!.rootViewController = vc
What is better is to
let goTo = UIStoryboard(name: "Onboarding", bundle: nil).instantiateViewController(withIdentifier: "notificationStoryboard") as! FirstOnboardingViewController
let nav = UINavigationController(rootViewController:goTo)
nav.isNavigationBarHidden = true
self.present(nav, animated: true, completion: nil)
the flow inside the onbarding should be with pushViewController
then to dismiss in the last onbaording vc
if let tab = (UIApplication.shared.delegate as! AppDelegate).window?.rootViewController as? UITabBarController {
tab.dismiss(animated:true,completion:nil)
}
My request is very simple and I am new in ios developing,
I want to show UITabBarController after login successfully
#IBAction func LoginAction(_ sender: Any) {
//correct me here!
let storyBoard = UIStoryboard(name: "Main", bundle: nil)
let tabbar:UITabBarController? = (storyBoard.instantiateViewController(withIdentifier: "LiveViewController") as? UITabBarController)
navigationController?.pushViewController(tabbar!, animated: true)
}
main.storyBoard storyBoard:
This
navigationController?
is nil in
navigationController?.pushViewController(tabbar!, animated: true)
You need
let tabbar = storyboard!.instantiateViewController(withIdentifier: "LiveViewController") as! UITabBarController
let nav = UINavigationController(rootViewController: tabbar)
nav.isNavigationBarHidden = true
(UIApplication.shared.delegate as! AppDelegate).window!.rootViewController = nav
I have implemented an EXSlideMenuController and added a TabBarController as a main view controller in the sliding menu controller but now I want to find out the first view controller of TabBarController which is inside the EXSlideMenuController.
let storyboard = UIStoryboard.init(name: "Main", bundle: nil)
let menuViewController = storyboard.instantiateViewController(withIdentifier: "menuViewController") as! MenuViewController
let initialViewController = storyboard.instantiateViewController(withIdentifier: "TabBarControllerID") as! TabBarController
let revealController = ExSlideMenuController(mainViewController: initialViewController, leftMenuViewController: menuViewController)
self.window?.rootViewController = revealController
self.window?.makeKeyAndVisible()
how do I find out the first view controller of tab bar controller from the ExSlideMenuController?
Here is the solution to find out the first view controller of a tab bar controller inside an ExSlideMenuController
let rootController = self.window?.rootViewController as! ExSlideMenuController
let customTabBarController = rootController.mainViewController as! CustomTabBarController
let navBarController = customTabBarController.viewControllers?.first as! UINavigationController
let storeController = navBarController.viewControllers.first as! StoreListViewController
may be it will help some other person.
I have few view controllers embedded in UINavigationController. The first view controller is login page. The second view controller is the home page. I want initialview controller as second view controller when the user is already logged in.
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool
{
// Override point for customization after application launch.
if let data = Locksmith.loadDataForUserAccount(userAccount: "someString")
{
if let userAccessToken = data["accessToken"]
{
if (userAccessToken as! String) != ""
{
let initialViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "HomePageViewController") as! HomePageViewController
loginResponse = LoginResponse()
loginResponse?.UserAccessToken = userAccessToken as? String
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = initialViewController
self.window?.makeKeyAndVisible()
}
}
}
return true
}
The problem is the subsequent view controllers are not embedded in navigation controller. Since it is not embedded in navigation controller I am not able to goback from one view controller to the other.
Add this in App delegate
first check user already login or not, if login then execute this code
let mainStoryBoard = UIStoryboard(name: "Main", bundle: nil)
let redViewController = mainStoryBoard.instantiateViewControllerWithIdentifier("respectiveIdentifier") as! ViewController
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.window?.rootViewController = redViewController
Use this in App Delegate and add an extension of UIStoryboard.
func checkForAlreadyLogin() {
let dashBoardScreen = UIStoryboard.dashBoardScreen()
let loginController = UIStoryboard.loginController()
if UserDefaults.standard.bool(forKey: UserDefaultValues().LOGINSTATUS){
self.window!.rootViewController = dashBoardScreen
}else {
self.window!.rootViewController = loginController
}
}
public extension UIStoryboard {
class func mainStoryboard() -> UIStoryboard { return UIStoryboard(name: "Main", bundle: Bundle.main) }
class func dashBoardScreen() -> HomeViewController?{
return mainStoryboard().instantiateViewController(withIdentifier: "HomeViewController") as? HomeViewController
}
internal class func loginController() -> LoginViewController?{
return mainStoryboard().instantiateViewController(withIdentifier: "LoginViewController") as? LoginViewController
}
}
Just call this checkForAlreadyLogin() method in 'didFinishLaunchingWithOptions'.
Also remember to set StoryboardID in the storyboard for each viewController.
This code did the trick for me.
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
if let data = Locksmith.loadDataForUserAccount(userAccount: "someString")
{
if let userAccessToken = data["accessToken"]
{
if (userAccessToken as! String) != ""
{
let initialViewController = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "HomePageViewController") as! HomePageViewController
let navigationController = self.window?.rootViewController as! UINavigationController
navigationController.pushViewController(initialViewController, animated: true)
}
}
}
return true
}
I want to redirect login view controller to mmdrawer controller in swift
if I am making only mmdrawer it works well because the code is under Appdelegate is working perfect .
var window: UIWindow?
var centerContainer: MMDrawerController?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
_ = self.window!.rootViewController
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
// let centerViewController = mainStoryboard.instantiateViewControllerWithIdentifier("LoginPageViewController") as! LoginView
//var rootViewController = centerViewController
let centerViewController = mainStoryboard.instantiateViewControllerWithIdentifier("CenterController") as! ViewController
let leftViewController = mainStoryboard.instantiateViewControllerWithIdentifier("LeftSideViewController") as! LeftSideDrawer
let leftSideNav = UINavigationController(rootViewController: leftViewController)
let centerNav = UINavigationController(rootViewController: centerViewController)
centerContainer = MMDrawerController(centerViewController: centerNav, leftDrawerViewController: leftSideNav)
centerContainer!.openDrawerGestureModeMask = MMOpenDrawerGestureMode.PanningCenterView;
centerContainer!.closeDrawerGestureModeMask = MMCloseDrawerGestureMode.PanningCenterView;
window!.rootViewController = centerContainer
window!.makeKeyAndVisible()
return true
but my question is how to add login view controller so can redirect it to mmdrawer on sucess .
Thanks
