You can change which tab is selected -- which also changes the highlight -- easily:

tabcontroller.selectedIndex = youNewIndexHere;

If your tabcontroller is in the app delegate (which is the case if you used the tab bar application template when you created your project) it would look something like this:

ProjectNameAppDelegate *appDelegate = (ProjectNameAppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate tabcontroller].selectedIndex = youNewIndexHere;

thanks! In the case of the selectedIndex, what would this be? The object ID? or the Tag? – Lilz Nov 05 '10 at 09:16

The new tab, 0 for the first tab, 1 for the second, etc. (If this works for you, please check the checkmark next to my answer.) – Matthew Frederick Nov 05 '10 at 09:24
I don't have a tabBarController but a UITabBar, does it work in the same manner please? – Lilz Nov 05 '10 at 09:40
UITabBar has a property called selectedItem that works the same way. – Matthew Frederick Nov 05 '10 at 12:53

tabbar works if you know the index and write it like this:

NSMutableArray *item [[NSMutableArray alloc] init];

[items addObject: [[[UITabBarItem alloc] initAsULike] autorelease]; <--- init as you like here

...

[tabBar setItems:items animated:FALSE];

tabBar.selectedItem = [items objectAtIndex: your_index]; <--- write your index here
[items release];

I've got a UITabBar, created in IB but without a TabBarController. In my awakeFromNib I just initialise it to the first item like this:

[self.tabBar setSelectedItem:[[self.tabBar items] objectAtIndex:0]];

Don't forget, the UITabBarDelegate didSelectItem does not get called in this case.
