I am writing a larger project and am trying to make a deprecated method “print” a #warning about the deprecation when the method is called.
How could I do so? Just again: I have this
#warning -methodname:(id)sender is deprecated, use ...
I only want this message appear in the build warnings, if the message is called, not all the time.
Place this after the declaration of the method, before the semicolon:
__attribute__((__deprecated__))
