AR & IR integration (App Crash on Navigation)

XCode Version: 4.6

Automatic Reference Counting (ARC): YES

iOS Versions: > 5.0.1

wikitude SDK Version: 1.2

I am using your both sample Projects (named SimpleARBrowser  &   SimpleIRSample ) And integrate them into one single project. I have not modified anything yet in your sample projects. I am just calling the webservices and data display into the AR Views. For IR View I have just change the function parameters to recognize the Target Images.

App Crash: Facebook Like Side Bar Navigation.

   1) Open AR Screen select any poi then goto details of poi. Again come back to the AR Screen. Now goto main screen then App will crash.

 Crash Reports:: Here I have two crash reports regarding to this and as follows by (A)  & (B).

 

      (A)       * thread #1: tid = 0x2403, 0x00060766 ARApp`- + 22, stop reason = EXC_BAD_ACCESS (code=1, address=0x60000014)

   2) Open AR Screen select any poi then goto details of poi. Now Here I am calling the Image Recognition View in the Next ViewController. After Image Recognition completes then multiple go back to main screen App will crash.

App Behaviour::  Sometimes display only Black AR Screen but not crashed at that time. now only one option remaining that click on the "back" navigation button then crash will happen.
