I'm trying to create login/protected page session page using Swift 3.0
Therefore, I created didFinishLaunchingWithOptions launchOptions function in AppDelegate.swift as below
AppDelegate.swift
import UIKit
@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 rootViewController = self.window!.rootViewController
let mainStoryBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let isUserLoggedIn:Bool = UserDefaults.standard.bool(forKey: "isUserLoggedIn")
if(!isUserLoggedIn){
let loginViewController = mainStoryBoard.instantiateViewController(withIdentifier: "loginview") as! LoginVC
window!.rootViewController = loginViewController
window!.makeKeyAndVisible()
}
else{
let protectedPage = mainStoryBoard.instantiateViewController(withIdentifier: "ViewController") as! ViewController
window!.rootViewController = protectedPage
window!.makeKeyAndVisible()
}
return true
}
}
It build successfully, But i got an error when apps run. The error as below
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Storyboard () doesn't contain a view controller with identifier 'loginview''
libc++abi.dylib: terminating with uncaught exception of type NSException (lldb)
