It works, try this:

******************************************main.m************************ 
********
#import <Foundation/Foundation.h>
#import "MyClass.h"

int main (int argc, const char * argv[]) {
     NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
     SEL message = NSSelectorFromString(@"giveMeAnA");
     NSString *result = objc_msgSend([MyClass class], message);
     NSLog(result);
     [pool release];
     return 0;
}
******************************************main.m************************ 
********

******************************************MyClass.h********************* 
***********
#import <Foundation/Foundation.h>


@interface MyClass : NSObject {

}

+ (NSString *)giveMeAnA;

@end
******************************************MyClass.h********************* 
***********

******************************************MyClass.m********************* 
***********
#import "MyClass.h"


@implementation MyClass

+ (NSString *)giveMeAnA
{
     return @"A";
}

@end
******************************************MyClass.m********************* 
***********
