iPhone: how to badge a TabBatItem?

Okay, I figured out that you can use Numbers in a badge.
With the following code it's possible to set the badge of the App-Icon.

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];

If anybody hasn't an idea how I solve my first told problem, maybe you know how I get the Information of the ApplicationBadgeNumber? It would help me, if could use something like this:

if (ApplicationBadgeValue = "1") {
...
}

Any idea?

I'am absolutly new in developing with Xcode. The documentation doesn't help me, becuase I don't understand what I have to do.

I've tried something like this:

self.tabBarController.tabBarItem.badgeValue=@"1";

It doesn't work and makes not sense to me, too. Because in the code, there isn't set the specified Item which the badge should display.

It would help me, if you give me some code, please!?

Thanks, this was more helpful, yes. But it doesn't work yet.

I have to put this code in my AppDelegate.h, right?

@property(copy) NSArray *items;

And then I have to sythesize "items" in my AppDelegate.m, right?

When I do this, I get two errors:
1. "request for member "items" in something not a structure or onion"
2. sythesized property "items" must either be named the same as a compatible ivar or must explicitly name an ivar"

It seems to be very complicated for me. I have linked my TabBarItem (which should get my badge) to another ViewController. Isn't it possible to put the needed code in my ViewController.h /.m ?

This would be easy I think, because later I want to get the Information if a badge is set - I will make this in my ViewController too.

I know, it's very difficult to help me, but I'am too new in developing. Maybe everyone has solved the problem yet, but I think I need an almost ready code in this case! Sorry!

It's terrible, it doesn't work. I got a lot of errors - I hate it.

Maybe you can help me in this problem:

It's another one, but it would solve my problem too - not looking so good, but it would work.

Now I have put out all of the new code which made erros, because I'm testing some other things.

But would you type in the right code for me if I post my .m and .h?
...by the way it's a very long code...

And to get the information if the badge is set, do you need my ViewController.m /.h right!? (there I have the if-clause)

Thank you so much!!!

Do you use iChat? I could share my screen, I think it would be the best way isn't it?

Okay, at first I think I should change the "index" to "4" like this, because my badge should display on item index 4:

tb.items objectForIndex:4

I've put the Code in the .h as you said. Than in IB I selected the Tab Bar and set the connection in "outlets -> delegate" to my .h.

The other code I put in my void which is calling when a button was clicked. I got any error but anything happens!

Where is my misstake? I also tried to set the referencing outlet in IB to *tabBar but when clicked my button my app crashes!
