Please give me Suggessions if u have to come up with is problem.

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.

Hi Andreas,

I too have the same problem of app getting freezed and crashing if run for a long time. I tried with the sample app you posted, that also crashes when run for a long time.

Hi,

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

Best regards

Andreas

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?

Andreas

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?

Regards

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.

Hi,

thanks for your detailed information. I'll do some tests today and can perhaps send you a new test version later that day.

Best regards

Andreas

Hi,

Please reply as soon as possible.

Thanks 

Abhishek
