I have the following defined in a custom Segue, let us call it SegueX:
@interface SegueX : UIStoryboardSegue
@end
@implementation SegueX
- (void)perform
{
The navigation bar and the tool bar should disappear in the storyboard when you change the segue -- that's normal. You can change the simulated metrics for the bottom bar to "Translucent Toolbar", which will add it back, so you can add buttons to it (you only want to change the simulated metrics, not drag in another tool bar which would add a second tool bar). You should still see both bars with their buttons at run time.
