Dear all;
For my application requirements, I Placed my "XML and DAT" Files in this path:
"var/mobile/Applications/AF238966-5A74-A656-9C50370BBDC7/Documents/MyTrackble.xml"
So i loaded my dataset in ImageTargetAppDelegate.mm by this line:
[qUtils addTargetName:@"Stones & Chips" atPath:@" var/mobile/Applications/AF238966-5A74-A656-9C50370BBDC7/Documents/MyTrackble.xml "];
unfortunately, it gives me this error "Failed to load data set"
this mean that it can't read my path ... what's the problem?
Hi Khaled1989
Just use the file name - you do not need the directory i.e.
[qUtils addTargetName:@"Stones & Chips" atPath:@"MyTrackble.xml "];
However in QCARUtils.mm you need to use STORAGE_ABSOLUTE rather than STORAGE_APPRESOURCE if you put the files in a directory rather than the App Bundle i.e.
NSString *fullPath = [NSString stringWithFormat:@"%@/Documents/%@",NSHomeDirectory(),dataSetPath];
if (!theDataSet->load([fullPath cStringUsingEncoding:NSASCIIStringEncoding], QCAR::DataSet::STORAGE_ABSOLUTE))
{
msg = msgFailedToLoad;
errorCode = QCAR_ERRCODE_LOAD_DATASET;
imageTracker->destroyDataSet(theDataSet);
theDataSet = nil;
}
Thank you it is work very well
