add UITabBarControllerDelegate

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

switch (tabBarController.selectedIndex) {
    case 1:
        table_mutableArray=nil;
        [table_mutableArray addObjectsFromArray:tab1_array];

        break;
     case 2:
        table_mutableArray=nil;
        [table_mutableArray addObjectsFromArray:tab2_array];

        break;
     case 3:
        table_mutableArray=nil;
        [table_mutableArray addObjectsFromArray:tab3_array];

        break;
    default:
        table_mutableArray=nil;
        [table_mutableArray addObjectsFromArray:tab4_array];
        break;
}
[tableview reloadData];
}
