This is just a question out of curiosity. In the developer docs, only
- (id)performSelector: is defined.
So I was going to write my own + (id)perfromSelector, but first
figured I'd check whether there was
one already by writing up a quick test in XCode - which it turns out
there is (saved me the work).
I figured it must just not be in the documentation, so I was going to
file a bug on the developer docs...
Yet, doing a classdump on Foundation.framework doesn't show +
performSelector either (only on
NSProxy, not on NSObject). Is there some magic going on? Is
+performSelector actually not defined
on NSObject and this is getting forwarded to NSProxy or something? Or
is this just a case of under
documentation and class dump not telling the whole truth?
Thanks,
Francisco
