is there a simple way (Delegation? Overwriting? Category?) do globally customize all the back buttons that are being used in the navigation bars throughout my whole app?
I don’t need custom text on them.
I don’t need custom actions on them.
I only need custom buttons background.
Almost all my view controllers are from NIB files.
All my view controllers share the same base class.
Thanks in advance!
Apparently it is impossible to customize only the background, as stated by one of the comments.
