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.

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?

Srikanth

Yes, the crash occurs everytime, I am using XCode 4.3.1 and iOS5.1

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.

I am using Wikitude 1.1.1, I strongly believe its something to do with sequential start/stop calls on ArchitectView. I think this issue relates to an earlier post on Wikitude forum http://forum.wikitude.com/home/-/message_boards/message/133681.

Please check on it and let me know what could be a possible nicer way to get around this problem.
