Question

I\'ve noticed a lot of examples for iPhone apps in the Application Delegate

- (void)applicationDidFinishLaunching:(UIApplication *)application

Just an update on this with the release of ios 6.

If still using the -[UIWindow addsubview:] boilerplate, you will probably get the message "Application windows are expected to have a root view controller at the end of application launch" in your console as well now. Along with potential rotation issues and layout issues in your app.

Setting the window's rootViewController as above will fix this too.
