问题
Well I have a problem,
I'm doing the reverse for my iPad app, but I want my tabbar is exactly like this:
I'll put the volume controls, play and pause on the left and right side of the tabbar icons ....
how can I change the position of them?

For alligning the elements, you should take a look at this question: Aligning UIToolBar items
I'm not sure how to add custom controls to a UIToolbar, but I'd expect you could do this by setting their frame to overlap the UIToolbar.
