How do you connect a tab bar item to an action?

Question

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.

This sounded like the most promising lead for me, but where the heck is this "File's owner" are you talk about? I don't see it anywhere. — SikoSoft, May 04 '15 at 10:58

It is not clear from your question if you also defined a UITabBarController.

If you did not (as I assume, otherwise clicking on a tab bar item should work if you correctly defined things in IB), the way to go is assigning a UITabBarDelegate to your UITabBar and define tabBar:didSelectItem:

Have a look at the reference for UITabBarDelegate

You can't set a target action to your tab bar items. They should always have a new view. The only way is - you should use delegates which determine that your tabbar item is touched and then handle which tab is pressed in that delegate.

- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item
{
    if(item.tag == 1)
    {
    }
}

You should set a tag value to your tab bar item from the properties in xcode.

Hi! What if one wants a "Touch down" action recognized on a TabBar Item (Instead of "selected" action)? How would that be done? – BadmintonCat Dec 07 '13 at 08:02
