Use the UIToolBar of the UINavigationController instead of creating your own.

[StefaniOSApps]

Is your feature request related to a problem? Please describe.
Currently, if you create the UIViewcontroller by programming, you have to create and position your own UIToolbar.

Describe the solution you'd like
I would love it if it worked directly with "self.navigationcontroller.toolbar". Just add it to the "followers" and you're done.

Describe alternatives you've considered
At present, extensive programming work is necessary to achieve the desired result.

Additional context
It would make it much easier to work with this framework, as the ScrollingNavigationController class already exists.
