Question

In my App i have a situation where i Programmatically change the selected index of a tabBarController like this

[self.tabBarController setSelectedIndex:0];

and go back to my tab containing a UITableView’ at this point i need to make some actions on my tableView
i tried to use viewWillAppear and it didn’t get there, i tried to make the view delegate like this

@interface ThirdViewController : UITableViewController < UISearchBarDelegate,UINavigationControllerDelegate, UITabBarDelegate> 

- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController{  

it didn’t work

any one know how to do it?

Answer 1

I noticed that your class ThirdViewController implements UITabBarDelegate, while tabBarController:didSelectViewController: is in fact a method of UITabBarControllerDelegate protocol.
