How to write a dictionary into an output file

Hi,
I'm trying to write son dictionary information in a file, and I 
realize that I can do it using the method

- (BOOL)writeToFile:(NSString *)path atomically:(BOOL)flag

and I use it like this:

+(TCLogger *) instance {
   NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
   NSDictionary *LogFile1 = [[NSDictionary alloc] initWithObjectsAndKeys:
       @"one", [NSNumber numberWithInt: 1],
       nil];
   
   if ([LogFile1 writeToFile: @"/Users/jbianco/pueba.log" atomically: 
YES])
       NSLog(@"escribio el archivo2");
   if ([LogFile1 writeToFile: [NSHomeDirectory() 
stringByAppendingPathComponent: @"Desktop/log.conf"] atomically: YES])
       NSLog(@"escribio el archivo");
   [LogFile1 release];
   [pool release];
   return instance;
}

and when I try to run it, that is not run Ok, because never prints 
those logs, and neither creates the file.
Can you tell me what am I doing bad?

Thanks
Julio
