ios - Call a function of an another class (protocol) -

-

i have slide out navigation panel (menu) , "menu" on first page.

enter image description here

slide out menu:

  • index
  • page 1
  • page 2
  • page 3
  • page 4

on index:

  • page 1
  • page 2
  • page 3
  • page 4

so user have access pages index or sliding (or tap on icon menu) have menu.

but have error: go page 1 index, tap on icon menu slide out menu tap on index, go page 1 again index, , here if tap again on icon menu, error: sigbrt (something that)

i did breakpoints:

on line: self.delegate?.pushviewcontrollerinstack!(uistoryboard.nosoffresviewcontroller(‌​)!)

and 1 in function pushviewcontrollerinstack

and when maniplations, app read line self.delegate?.pushviewcontrollerinstack!(uistoryboard.nosoffresviewcontroller(‌​)!) don't go in function.

so view lost access of function, don't know why , how fix issue.

there's lot of code, can find git repository here: https://github.com/vkt0r/slideoutsidebartest

the error:
