I want to use AppNavigationController and AppNavigationDrawerController in the same view, but it is not seen correctly. Thanks
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
let leftViewController = LeftViewController()
let root = PatientListController()
let appToolbarController = AppToolbarController(rootViewController: root)
let appNavigationController = AppNavigationController(rootViewController: appToolbarController)
let appNavDrawerController = AppNavigationDrawerController(rootViewController: appNavigationController, leftViewController: leftViewController)
window = UIWindow(frame: UIScreen.main.bounds)
window!.rootViewController = appNavDrawerController
window!.makeKeyAndVisible()
return true
}
Result
For now I'm using NavigationDrawerController with ToolbarController in the same page. I did my AppDelegate.swift file something like this.
import UIKit
import Material
extension UIStoryboard {
class func viewController(identifier: String) -> UIViewController {
return UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: identifier)
}
}
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
Override point for customization after application launch.
let appToolbarController = AppToolbarController(rootViewController: DashboardVC())
let leftNavigationVC = LeftNavigationVC()
window = UIWindow(frame: Screen.bounds)
window!.rootViewController = AppNavigationDrawerController(rootViewController: appToolbarController, leftViewController: leftNavigationVC, rightViewController: nil)
window!.makeKeyAndVisible()
return true
}
}
BTW, I'm using Swift 3.

I have installed KYDrawercontroller in my project. it is available in project and can able to import it.any help will be appricated.thanks in advance
As you can check in KYDrawerController docs you have to use DrawerViewController and KYDrawerController, there isn't DrawerController:
import UIKit
import KYDrawerController
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
let mainViewController = MainViewController()
let drawerViewController = DrawerViewController()
let drawerController = KYDrawerController()
drawerController.mainViewController = UINavigationController(
rootViewController: mainViewController
)
drawerController.drawerViewController = drawerViewController
/* Customize
drawerController.drawerDirection = .Right
drawerController.drawerWidth = 200
*/
window = UIWindow(frame: UIScreen.mainScreen().bounds)
window?.rootViewController = drawerController
window?.makeKeyAndVisible()
return true
}
I have created a basic single view application. Using Xcode 11 now. I always build apps programatically because the tutorials I have started with never use the interface builder. For some reason not able to get the pushViewController to work. Seems to work just fine in my other projects built using Xcode 10.
In App Delegate
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
window = UIWindow()
window?.makeKeyAndVisible()
let nc = UINavigationController(rootViewController: ViewController())
window?.rootViewController = nc
return true
}
In my viewController
#objc func handleChat(){
print("Chat pressed")
navigationController?.pushViewController(InboxViewController(), animated: true)
}
AppDelegate.swift
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
let VC = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "ViewController") as? ViewController
var Nav: UINavigationController? = nil
if let VC = VC {
Nav = UINavigationController(rootViewController: VC)
}
window?.rootViewController = Nav
return true
}
Remove SceneDelegate.swift
Goto Info.plist
Remove Application Scene Manifest
It's work for me.
I have an app written in Swift 3.1, using Xcode 8.3.3.
I am currently trying to implement state preservation/restoration.
To do this I have implemented shouldSaveApplicationState and willFinishLaunchingWithOptions methods in AppDelegate.swift and set to return true:
// AppDelegate.swift
// STATE RESTORATION CALLBACKS
func application(_ application: UIApplication, shouldSaveApplicationState coder: NSCoder) -> Bool {
debug_print(this: "shouldSaveApplicationState")
return true
}
func application(_ application: UIApplication, shouldRestoreApplicationState coder: NSCoder) -> Bool {
debug_print(this: "shouldRestoreApplicationState")
restoringState = true
return true
}
func application(application: UIApplication, willFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
debug_print(this: "willFinishLaunchingWithOptions")
return true
}
I’ve also provided restoration IDs for all involved viewcontrollers and navigationcontrollers.
I'm using a 3rd party library to handle side drawer navigation container (https://github.com/sascha/DrawerController). The initial viewcontroller is set programmatically inside the didFinishLaunchingWithOptions method, see below.
// AppDelegate.swift
var centerContainer: DrawerController?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let centerViewController = mainStoryboard.instantiateViewController(withIdentifier: "RootViewControllerNav") as! UINavigationController
let leftViewController = mainStoryboard.instantiateViewController(withIdentifier: "SideDrawerViewController") as! UITableViewController
centerContainer = DrawerController(centerViewController: centerViewController, leftDrawerViewController: leftViewController)
centerContainer?.restorationIdentifier = "DrawerControllerView"
window = UIWindow(frame: UIScreen.main.bounds)
window?.restorationIdentifier = "MainWindow"
window?.rootViewController = centerContainer
window?.makeKeyAndVisible()
return true
}
When app opens and attempts to restore state, it displays the correct viewcontroller (last controller before app closed) temporarily, then once app becomes active it reverts back to the initial viewcontroller.
For example, the following happens:
Open app Navigate to the “settings” view via the side menu
Navigate to the home screen
Stop running xcode and start it again
App will open showing settings view, then revert back to home view
Can anyone tell me what is causing this, or where I am going wrong? Let me know if you need any more code examples.
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let leftSideDrawerViewController = mainStoryboard.instantiateViewController(withIdentifier: "SideDrawerViewController") as! UITableViewController
let centerViewController = mainStoryboard.instantiateViewController(withIdentifier: "RootViewControllerNav") as! UINavigationController
let navigationController = UINavigationController(rootViewController: centerViewController)
navigationController.restorationIdentifier = "navigationControllerKey"
let leftSideNavController = UINavigationController(rootViewController: leftSideDrawerViewController)
leftSideNavController.restorationIdentifier = "LeftNavigationController"
self.drawerController = DrawerController(centerViewController: navigationController, leftDrawerViewController: leftSideNavController, rightDrawerViewController: nil)
self.drawerController.openDrawerGestureModeMask = .all
self.drawerController.closeDrawerGestureModeMask = .all
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = self.drawerController
return true
}
I downloaded sample code from here for a location tracking application https://www.pubnub.com/blog/2015-05-05-getting-started-ios-location-tracking-and-streaming-w-swift-programming-language/. I am trying to run the application but in the AppDelegate class I am getting an error saying "Class AppDelegate has no initializers". What is causing this error and how can I fix it?
import UIKit
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
// MARK: - Properties
//var window: UIWindow?
var window = UIWindow(frame: UIScreen.mainScreen().bounds)
// MARK: - App Life Cycle
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Adding a Navigation Controller and tool bar
self.window.rootViewController = UINavigationController(rootViewController: MainViewController(nibName: nil, bundle: nil))
// Make window visible
self.window.makeKeyAndVisible()
return true
}
}
I would set the window to be an optional value with no default. just as you originally had then commented out
var window: UIWindow?
then give window a value and programmatically add the root view controller when your app launches
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
let viewController = ViewController(nibName: nil, bundle: nil) //ViewController = Name of your controller
let navigationController = UINavigationController(rootViewController: viewController)
self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
self.window?.rootViewController = navigationController
self.window?.makeKeyAndVisible()
return true
}
I want to set the rootViewController in the app delegate ..
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
var rootView: MyRootViewController = MyRootViewController()
//Code to set this viewController as the root view??
return true
}
If you are using a storyboard and want to set your rootViewController programmatically, first make sure the ViewController has a Storyboard ID in the Identity Inspector.
Then in the AppDelegate do the following:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// get your storyboard
let storyboard = UIStoryboard(name: "Main", bundle: nil)
// instantiate your desired ViewController
let rootController = storyboard.instantiateViewControllerWithIdentifier("MyViewController") as! UIViewController
// Because self.window is an optional you should check it's value first and assign your rootViewController
if let window = self.window {
window.rootViewController = rootController
}
return true
}
You can do something like this.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
var rootView: MyRootViewController = MyRootViewController()
if let window = self.window{
window.rootViewController = rootView
}
return true
}
Swift 2.0:
var window: UIWindow?
var storyboard:UIStoryboard?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
window = UIWindow(frame: UIScreen.mainScreen().bounds)
window?.makeKeyAndVisible()
storyboard = UIStoryboard(name: "Main", bundle: nil)
let rootController = storyboard!.instantiateViewControllerWithIdentifier("secondVCID")
if let window = self.window {
window.rootViewController = rootController
}
In order to get it to show there are some things you need to do if you are not using a storyboard. Inside the AppDelegate inside the function application.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
let frame = UIScreen.mainScreen().bounds
window = UIWindow(frame: frame)
let itemsViewControler: UITableViewController = BNRItemsViewController()
if let window = self.window{
window.rootViewController = itemsViewControler
window.makeKeyAndVisible()
}
return true
}
if let tabBarController = self.window!.rootViewController as? UITabBarController
{
tabBarController.selectedIndex = 0
}
