tag for UITabBarItem

Question

When I use the this method to initialize a UITabBarItem:

- (id)initWithTitle:(NSString *)title image:(UIImage *)image tag:(NSInteger)tag

Do I need to have a distinct tag for each tab bar item, or (since I don't use them) can I simply use the same tag value for all of them?

I'm pretty sure you can just leave them all as 0 or any other number you choose. Every UIView can potentially have a different tag, and Interface Builder sets them all to 0 by default. I haven't run into any problems with this.

My iPhone app had all of them 0 for a long time and it was fine. Now i'm going to set them to values just so I can do 'if' or 'switch' statements to easily identify which element is sending events etc. – Jonathan Oct 19 '13 at 23:35

From Apple's UITabBarItem class reference:

tag - The receiver’s tag, an integer that you can use to identify bar item objects in your application.

So it looks like it doesn't really matter.

I saw that, but it seemed unclear whether they use it for anything. – Sophie Alpert Jun 19 '09 at 22:37
Just by us to "identify objects" – Jonathan Oct 19 '13 at 23:36
