int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
 
	ConnectionDelegate *connectionDelegate = [[ConnectionDelegate alloc] init];
 
	NSURL *baseURL = [[NSURL URLWithString:@"http://store.apple.com"] retain];
	NSURLRequest *request =
	[NSURLRequest requestWithURL:baseURL 
					 cachePolicy:NSURLRequestUseProtocolCachePolicy 
				 timeoutInterval:60.0];
 
	NSURLConnection *connection = [NSURLConnection connectionWithRequest:request
																delegate:connectionDelegate];	
	if (connection) {
		[connectionDelegate setReceivedData:[[NSMutableData data] retain]];
	}
 
	[pool drain];
    return 0;
}

Avec ce code, rien ne s'affiche dans la console.

Quelqu'un peut-il m'éclairer.

Merci.
