From Crashlytics i am getting this kind of crashes
its only happening in ios. There is no problem for android
i could not figure out what casing this crashes
From Crashlytics i got this suggestion
Based on the stack trace displayed here, it looks like new calls triggering OpenGL rendering took place while the app was transitioning to, or from, a background state. If you set up OpenGL drawing in your app delegate's methods, make sure that you only did so in applicationDidBecomeActive:, never in application:willFinishLaunchingWithOptions: or application:didFinishLaunchingWithOptions:. According to some reports, even displaying an FPS indicator for SpriteKit could cause rendering to occur before it is allowed.
But current cocos2dx system how this is possible?
Please Help me
