I have a set of plugins which I load via a custom framework. The plugins load
and behave correctly in the UI.
I have a set of corresponding "rule" objects, one for each class of plugin. A
plugin may load data from a rule, and a rule may load data from a plugin:
-[RSRule loadFromPlugin:(RSPlugin*)plugin] or -[RSPlugin
loadFromRule:(RSRule*)rule]. I have moved away from using categories to do
this and the classes implement these methods internally. The header files list
the methods correctly.
However, after a clean and build, attempting to invoke any of these
-[loadFrom..:] methods causes a crash reporting "unrecognized selector".
A typical error message:
2012-07-10 20:42:39.791 Trixie[41453:303] -[RSReactionRule loadFromPlugin:]:
unrecognized selector sent to instance 0x1018961b0

Any advice on how I could narrow down what is causing this? I have tried using
repondsToSelector: but this doesn't do anything but confirm what the error
message states, that the selector is not recognized.
