Answer 1

You cannot pass variadic arguments directly. But some of these methods provide an alternative that you can pass a va_list argument e.g.

#include 

-(void)printFormat:(NSString*)format, ... {
   // Won't work:
   //   NSString* str = [NSString stringWithFormat:format];

   va_list vl;
   va_start(vl, format);
   NSString* str = [[[NSString alloc] initWithFormat:format arguments:vl] autorelease];
   va_end(vl);

   printf("%s", [str UTF8String]);
}
