You can add a bar button of type UIBarButtonSystemItemFlexibaleSpace in the place where you want the space.

UIBarButtonItem *barButton1 = ...
UIBarButtonItem *barButton2 = ...

UIBarButtonItem *flexibleSpaceBarButton = [[UIBarButtonItem alloc] 
                           initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace 
                                                target:nil
                                                action:nil];

toolbar.items = [NSArray arrayWithObjects:barButton1, 
                                          flexibleSpaceBarButton, 
                                          barButton2, nil];
