stop user changing tabs till app loads fully

Question

Hi guys,

im my app i have had to thread the loading of xml so the app loads and does not get kicked out by the os , but that also means that when the app loads and , the user selects one of the tabs that is still loading, it crashes.

is there any way i can stop them changing tabs till the app is fully loaded?

Thanks

Answer 1

You need to implement UITabBarControllerDelegate. Reference is here UITabBarControllerDelegate Protocol Reference

Answer 2

UITabBarController provides a delegate method called tabBarController:shouldSelectViewController:. Override that and return NO for any view controller you don't want to load.
