Ah, duh... I was trying to build the project for 10.1, and assumed
that the oddities surrounding the documentation were a symptom of my
problem. Thanks for your insight, everyone who responded.

The online cocoa documentation lists this method in NSObject:
- (void)performSelectorOnMainThread:(SEL)aSelector withObject:(id)arg
waitUntilDone:(BOOL)wait
However, the NSObject.h file in /System/Library/Frameworks does not
list this method. I assume this is why I'm getting a compiler
warning on my app regarding my usage of
-performSelectorOnMainThread:. The app works just fine though...
So where is this method actually declared? Why is there this
inconsistency? What can I do about this compiler warning? (I really
hate having compiler warnings.)
No inconsistency exist, it is common for methods to be added to
classes via categories. Also you didn't list what compiler warning you
are seeing so we cannot help you with it...
Anyway, it is an NSThread addition on NSObject. In Xcode you can
command double click on a symbol to get the header that defines it to
pop up, in this case NSThread.
From NSThread.h...
#if MAC_OS_X_VERSION_10_2 <= MAC_OS_X_VERSION_MAX_ALLOWED
@interface NSObject (NSMainThreadPerformAdditions)
- (void)performSelectorOnMainThread:(SEL)aSelector withObject:(id)arg
waitUntilDone:(BOOL)wait modes:(NSArray *)array;
- (void)performSelectorOnMainThread:(SEL)aSelector withObject:(id)arg
waitUntilDone:(BOOL)wait;
// equivalent to the first method with kCFRunLoopCommonModes
@end
#endif
Note as documented it is only available on 10.2 and later.
