When I use objc_msgSend with something that doesn't exist on 10.2 but
exists on 10.3 on a 10.2 system, I get a "selector not recognized"
warning in the console every time I call it -
objc_msgSend(GetNSView(),@selector(getRectsBeingDrawn:
count:),&rects,&countRects);
Is there something better to use in this circumstance than
objc_msgSend? Is there a way to turn off this warning? Or is an
#ifdef required in this circumstance?
Why don't you do a runtime check to see whether the selector you wish
to use is implemented? If it's not implemented, don't call it...
