I have a UIView which has a UITabBar with 4 UITabBarItem components in it (all created from IB).

I want my IBAction function called when someone clicks on the items in the tab bar. But I am unable to connect the tabbaritem to my action via IB... I control drag from the "received actions" but it does not allow me to connect that to the tabbaritem.

Thanks Deshawn

Control drag your tabbar to your "File's owner" in IB and set it as the delegate. Next drop this code in your viewcontroller.m file:

- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item
{
    if(item.tag == 0)
    {
        //party like its 1999 right here
    }
}

Go back to IB and set each tab bar item in your tab bar with a tag. You gotta test for each case in your didSelectItem, so if you got more than one set a different tag etc. Thats how I did it anyway.
