November 15, 2012 - 11:00am #1

last month, my app was perfectly work.


but now, i move my application folder, it doesn't work well.


it crash at  dataset load part in ' QCARutils.mm '  

- (QCAR::DataSet *)loadDataSet:(NSString *)dataSetPath 




if (!theDataSet->load([dataSetPath cStringUsingEncoding:NSASCIIStringEncoding], QCAR::DataSet::STORAGE_APPRESOURCE))



my .dat and .xml file is fine , but always crash at that point and show EXC_BAD_ACCESS at Thread 3.

Thanks for reply, NalinS.


I did move application folder back, but didn't work.


I'm newbie to programing.


So I see the tutorial of Vuforia and make this project step by step


I make this project alone, AtoZ made by me.....  Of course, sometimes google help me.


last weekend, I ask to another iOS programmer, but they don't know about vuforia, so they didn't solve the problem.


just they find 'QCAR/DATESET -> LOAD' function has some problem or that can't find .xml file. ( they didn't find what cause this problem. T_T)


So, I will remake this project.

Hi evados

Can you not move your application folder back?

As I explained after looking at the project that you sent through, the .dat and .xml files work fine, and it looks like the project was put together quite competently and must have been working as it was quite a large size.

Why it is not working only maybe you can explain?  Is it not possible to get the person who created the project to help you?
