Ipad header bar multiple buttons


I am building an application specific to tablet sized devices and would like to have more then just a left/right button along with header text. I am looking for more like what Bootstratp supports where you can basically have any control in the header. Mostly button bars for various activities. Part of the app will allow for building a floorplan and I want to display a toolbar for a header containing buttons for all of the edit controls.

This way the space for the floorplan will be maximized - I do want the toolbar/header to be fixed. Any suggestions or recommendations?
