objective c - Buttons are not working -

hello next this tutorial little bit of enhancements of own. unfortunately stuck @ 1 point can't find out do.. (i doing of training/learning purposes im pretty new ios development).

at step have add segue navigate back did whatever tutorial said won't bring me original view 1 time @ viewcontroller , press cancel or done.

i did add together new header file called grocerylisttableviewcontroller.h containing

@interface grocerylisttableviewcontroller (workaround) -(ibaction)unwindtolist: (uistoryboardsegue *)segue; @end

and have changed classname of grocerylisttableviewcontroller.swift

@objc(grocerylisttableviewcontroller)class grocerylisttableviewcontroller: uitableviewcontroller

then lastly step pointed both buttons exit element above viewcontroller.

somehow works except 2 buttons. doing wrong here?

the woraround separate .h file beta versions of xcode , no longer necessary. can delete .h file.

in class file segue should go to, set code want perform, such as:

@ibaction func cancel(segue: uistoryboardsegue!) { // code here } @ibaction func done(segue: uistoryboardsegue!) { // code here }

then, in storyboard ctrl-drag navigation button exit icon:

when release mouse button, 2 functions appear. take appropriate action button:

that's it. hope helps.
