Approach to make a custom tabBar

-------------Problems Reply------------

I would recommend using an UIImageView for the blue background, then 5 UIButtons of custom type with PNG images for the actual buttons.

Subclass UIView and put all the code to set up the background and buttons in the init function. That way you can easily place your custom TabBar wherever you like.

The individual buttons also allow you to easily animate them for transitions if you want.

Update to reflect updated question:

If you want the actual UITabBar functionality, things become much more complex.

You have three basic options:

a) Implement the functionality you need from scratch in your new class

b) Subclass UITabBar and try to override the drawing code with the code above

c) Take a look at already existing alternative implementations of UITabBar and base your new class on one of them. This will probably be the easiest solution.
