Is it safe to use -[NSApplication targetForAction:] with non-action selectors? For example, selectors that have more than one argument, non-id first argument, or return values?

The documentation for targetForAction:to:from: seems to imply it just does a respondsToSelector: on each object in the responder chain, and it seems to behave this way in my tests. I'd just like to make sure it is safe to rely on this behavior, or if we should find some other approach.


What exactly are you trying to do?

I'd say it's not safe, since that usage isn't anticipated, or necessary. If you could perhaps outline why you think you need it a better solution can be suggested.

cheers, Graham
