How to change RootViewController (in AppDelegate) from within CustomViewController?
11,488
[appDelegate.window addSubview:appDelegate.tabbarController.view];
[self.view removeFromSuperview];
appDelegate is the application shared delegate.
MyAppDelegate *delegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];

Good day,
My app has authorization form (SigninController) which is loaded in AppDelegate, and after signing in (checking is in SigninController.m) TabBarController should appear (as main view of application).
How can I change controller from Signin to TabBar and where ??
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { SigninController *aSigninController = [[SigninController alloc] initWithNibName:@"SigninView" bundle:nil]; self.currentController = aSigninController; [aSigninController release]; self.window.rootViewController = self.currentController; [self.window makeKeyAndVisible]; return YES; }
SigninController.m
- (IBAction)signinClick { ........ if (loginOK == YES) { //This place is ready to send messages to show TabBar } else { UIAlertView *alert = ...... [alert show]; [alert release]; } }

pulkitsinghal over 11 yearsI was using
self.view.window.rootViewController = self.loadThisViewWhenDone
for loading my tab bar controller but that stopped working when I tried to set a nav bar controller! I'm not sure why but using your code helped :) -
eladleb almost 11 yearsIt's a great answer. I think it would be nicer to reorder the code lines, so they are in the correct order and rename delegate to appDelegate.
