Geolocation looses pointer in background

Hello, I need some help in my project. We developed an augmented reality app for a customer and he asked us for geolocation feature. In all moments: App killed (closed), background and app opened. The main goal is to check if (and when) their sales team are visting some clients. So we need to track full time in iOs and Android and send the infos to a MySQL database.

What is happening is: we created a geolocation plug-in in objective-C and C++ running in foreground. But when I build the app and open it on an iOs device the app suddenly crashes in seconds... or after accessing the augmente reality camera, or the video library integrated with youtube.

The pointer for the plug-in class instance gets lost sometime after the initialization. I already setted the property as strong and as retain... and it didn't had any effect.

The android version runs ok tough.,Hello, I need some help in my project. We developed an augmented reality app for a customer and he asked us for geolocation feature.
