I am in the appdelegate of my application. How can I add a modal view controller in the "didfinishlaunching" method?
I tried the following but did not work
SomeViewController *vc = [[SomeViewController alloc]init];
[self.tabController.navigationController presentModalViewController:vc animated:NO];
EDIT: I changed my implementation to the following
self.tabController.selectedViewController
= [self.tabController.viewControllers objectAtIndex:0];
SomeViewController *vc = [[SomeViewController alloc]init];
[self.tabController.selectedViewController presentModalViewController:vc animated:NO];
I checked that the 'selected view controller' is not null... however I am still not able to get the output I needed. Is there anything I am missing?

The app delegate is effectively the root object of your app, and it works in conjunction with UIApplication to manage some interactions with the system. Like the UIApplication object, UIKit creates your app delegate object early in your app's launch cycle so it's always present.
The application delegate is a controller object. By default, it is the owner and controller of the main window -- which is a view -- in an iOS app. The app delegate receives messages from an object representing -- or modeling -- the application itself (an instance of UIApplication ).
Assuming tabController and navigationController are not nil, the applicationDidFinishLaunching may be too soon to display the modal view controller.
[self.window makeKeyAndVisible];
UIWindowDidBecomeKeyNotification for that window
