How can I test a specific screen in my app without navigating all hierarchy until there

Say you are developing Settings.app (the iPhone settings app) and you want to add features in the Text Replacement system.

To test that screen one must go through all the screens Settings > General > Keyboard > Text replacement which is very painful if you do it often.

What are the options to directly test the Text Replacement screen? Or, alternatively, to go the specific screen quickly?

Have in mind that usually we set things up on the previous screens: state, singletons, global variables, etc…

I know there's no magic way to do it. What I'd like to know then is what are your tricks and advices (you use different schemes? you organize your state code in a way that's easier to test the screen?)
