reload view controller when tab pressed

Question

Hello,

I have several tabs in my tab bar controller and only one (the first one) for which I would need an automated reload each time I select its tab (and also when the app come back to the foreground).

I did not find how to do this, do I need to recreate the tab bar controller manually each time ? Do I need to add a new set of view controllers to the tab bar controller ?

Thanks for your help

Answer 1

Would it make sense to have a updateView functio that you can call in viewWillAppear on that particular view that ensures everything is up-to-date each time the view is set to appear?

Answer 2

If your UIViewController is a UITabBarControllerDelegate it will get this callback, which is what you want, I believe:

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController

Simply return YES after calling your updateView method.
