iPhone Create View Before TabBarController on tab bar application template

I'm getting pretty good at using xcode and objective c, but only from the templates.

I wish my application to load to a view to login before it reaches the tab bar controller that i have set up.

I believe this can be done in the 'didfinishlaunchi开发者_StackOverflow社区ngwithoptions' section of the app delegate but after that I don't have any idea how once the login is successful that i can show the tab controller again.

i'll be grateful for any help :)

Use modal views for this. Sample example here.

I think you want something like this

    LoginViewController *loginViewController = [[[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil] autorelease];
    [tabBarController presentModalViewController:loginViewController animated:YES];

inside didfinishlaunchingwithoptions
