Hi,
I created a simple App which demonstrates the usage of UINavigationController with the Wikitude SDK.
Hopefully you can find out whats the problem with your Application and fix it.
Best regards

Hi,
on which device are you running the app and how long does it run until it crashes?

Hi Andreas,
I am running the app on iPhone 4S, the same happens even on iPhone 3GS.
This behaviour is occuring when the app runs for 5-10 mins.

Hi,
thanks for your information. Are you interacting in any kind with the device in this period or does it only rest on your desk?

Hi,
Which iOS and Xcode version are you using? Does the crash occur every time the ARView is shown more than 10 minutes?

I do sometimes but most of the times I observed the crash is when its idle.
Do we need to call AR.ARchitectObject.destroy(); once we are done with the AR functionality?

Hi Andreas,
To update you on my observations since yesterday, I have frequent start/stop/start/... calls on my ArchitectView when ever I switch between AR and non AR Views, and I guess the issue is occuring because of CMMotionManager also being started and stopped as we start/stop ArchitectView. To confirm this what I did is I removed the call to stop on ArchitectView and the now the app doesn't crash, its been 15-20 mins since I ran the app.
