How to make a save state run a function

OK, we have detailed code, but what is exactly the problem ?

VC gets call but without running the function

What do you mean by VC gets called ? How do you knos ?

Which function is not run ?

Where is the class of ConductorPrincipalViewController

Where do you call saveState() ?

You say checkSaveStatechofer() is called instead.

Where is it called ?
