disable all uitabbaritems on launch of iPhone application

[inforeqd51]

My requirements is that whenever the application launches, i need to show a company Logo fill screen image view with the uitabbar at the bottom of screen with all uitabbaritems disabled.

The user will continue to see this logo view till he chooses to click on any of the tabbaritems and then the related view controller comes up

I've tried setting the [tabItem setEnabled:enableState]; to FALSE in the appdelegates application:didfinishlaunchingwithoptions: just before the below but still did not get the above behaviour:

self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
Can you pls suggest how this can be achieved?

Thanks,
