Help with UITabBarController

Can't do second step of the practice, I'm using this code

import "MainViewController.h"

import "UITabBarItem.h"

@implementation MainViewController

  • (void)viewDidLoad { [super viewDidLoad];
    NSArray *tabBarItems = self.tabBarController.tabBar.items; [self.tabBarController setSelectedIndex:2]; UITabBarItem *tab = [[UITabBarItem alloc] init]; [self.tabBarItems setSelectedIndex: tab];

any ideas what is wrong with it, thanks.

the task states: ** Declare a UITabBarItem variable named tab and set it from tabBarItems. Use the selectedIndex we just set as the index for the tab you get from the tabBarItems array.**

so the left side you have is correct, however you dont have to allocate and init your tab item, you just need to set it using 

UITabBarItem *tab = [tabBarItems objectAtIndex:self.tabBarController.selectedIndex];
