如何切换主视图控制器iOS5？

Question

I want to implement authorization for my application. If the authorization function returns yes, i want to switch my main view controller and assign my second view controller as initial view controller. I don't want to see authorization view any more after the function returns yes. What should i try?

Like transitionFromViewController or not?

Answer 1

Just load the main view controller and if you need to authenticate present a modal view over the view controller

[self presentModalViewController:myLoginViewController animated:NO];

or

[self presentViewController:myLogingViewController animated:NO completion:NULL];
