此代码给出了确切的字节数。

- (unsigned long long int)folderSize:(NSString *)folderPath {
    NSArray *folderArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:folderPath error:nil];
    NSEnumerator *folderEnumerator = [folderArray objectEnumerator];
     NSString *folderName;
     unsigned long long int fileSize = 0;

     while (folderName = [folderEnumerator nextObject]) {
      NSDictionary *folderDictionary = [[NSFileManager defaultManager] fileAttributesAtPath:[folderPath stringByAppendingPathComponent:fileName] traverseLink:YES];
    folderSize += [folderDictionary folderSize];
}

   return folderSize;
}

希望它有所帮助...
