Problème for "implementation"

I have a warning

What is missing ?
Thank you

PS: I get this warning on any example from the books Objective C and cocoa

It may be that you haven’t defined a method that you have declared in the interface part of the class.


Yes, it was a stupid typo.
I looked for 3 or 4 times comparing each lines between .h and .m but…
The following command line can help, those who like me, have bad eyes…

grep '^-' fic.h

And later on the fic.m
It’s easier to compare.
