Navigation Button item with TabBar

[TheGame]

I'm new to iphone SDK development, I just want to clear this up. I'm currently developing an app that has Navigation Button item (Add) in the top right side.. in the center I have tableView that renders data list and lastly I have tabBar at the bottom. I was confused because when I included the tabBar the Navigation Button item (add) is not showing, On the other hand when I removed the tabBar my Navigation Button item (add) is displaying, Is there a proper way to set up or code this kind of app???


Thanks in advance..
