UITabBarcontroller, UITableView and pushView

Question

I have a UITabBarController with a set of tabs. Some of them, when selected, show you a table. The cells of the table, if touched, bring the user to a detail screen of the object in the cell itself using a "pushViewController".

When I click to a different tab, and I am in the detail page, I see the new tab page. And this is fine. When I click back to the previous tab I would like to have shown again the table and not the detail page...

Is this possible?

Thanks!

Answer 1

It is possible. Code:

// Called when the user selected a tab. In iOS3+, called even when no change occurs.
- (void)tabBarController:(UITabBarController *)tabbarcontroller didSelectViewController:(UIViewController *)viewController
{
    UINavigationController *nav = (UINavigationController *)viewController;
    [nav popToRootViewControllerAnimated: NO];
}

Explanations:

• this is in your AppDelegate.
• Your AppDelegate is a UITabBarControllerDelegate.
• You set your UITabBarController's delegate (in InterfaceBuilder) to the AppDelegate.
• Your tabs must contain root controllers that are navigation controllers (must be, else your wouldn't be able to 'push' details).
