Conversion specifies type 'unsigned int' but the argument has type 'unsigned long long'

Been quite busy with maintenance issues lately (close to release), no time to blog. So here's just a small tip until I get into more interesting new development tasks:

unsigned long long bodyLen =
  (unsigned long long) [self.bodyPrefix length] +
  // ALAsset defaultRepresentation size returns (long long)
  (unsigned long long) fileSize +
  (unsigned long long) [self.bodySuffix length];
DLog(@"Total data size to send: %llu", bodyLen);
[request setValue:[NSString stringWithFormat:@"%llu", bodyLength] forHTTPHeaderField:@"Content-Length"];

In case you missed, the "printf" parameter to display unsigned long long is %llu...
