NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];

GTLDriveFile *newFile = [GTLDriveFile object];
newFile.mimeType = @"application/vnd.google-apps.docuemnt";

// another text parameter
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"parameter2\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
