objective-c hello world

I just started learning objective-c and cocoa a few days ago, and here is how I wrote an overly complicated objective-c "hello world" application.

MyClass.h:

#import <objc/Object.h>

@interface MyClass : Object {	
}

- (void) sayHello;

MyClass.m:

#import "MyClass.h"
#import <stdio.h>
@implementation MyClass : Object {
	
}

- (void) sayHello { printf("Hello, World!\n"); }

main.m:

#import <objc/objc.h>
#import "MyClass.h"

int main() {
	MyClass *anObject;
	
	anObject = [[MyClass alloc] init];
	[anObject sayHello];
	
	return 0;
}

I compiled this using the following:

gcc -o hello -lobjc MyClass.m main.m
