Hi Vuforia,

I am downloading .xml and .dat from server . 

My downloading method is:-

NSString *urlToDownload = @"https://s3.amazonaws.com/uploads.hipchat.com/122799/3164901/O7QFARbEJUbmEbo/shopping.xml";

        NSURL  *url = [NSURL URLWithString:urlToDownload];

        urlData = [NSData dataWithContentsOfURL:url];

        if ( urlData )

        {

            NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

            NSString  *documentsDirectory = [paths objectAtIndex:0];

            NSString  *xmlFilePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"result.xml"];

            NSLog(@"Downloading Started %@",xmlFilePath);

            filePath = [xmlFilePath lastPathComponent];

            //saving is done on main thread

            [urlData writeToFile:filePath atomically:YES];

        }

same for.dat.

I used :-

if (!dataSet->load([dataFile cStringUsingEncoding:NSASCIIStringEncoding], Vuforia::STORAGE_ABSOLUTE)) { }

I get error  "failed to load dataset".

Please help me asap.
