Application with native extension crashes onstart

Question

I've created a flex mobile project with ios native extension(with ad frameworks such as facebook,chartboost ) and linked 3rd party frameworks.
when I start the application,it's crashes.I can't see any logs.is this a problem with linking 3rd party frameworks?
framework didn't work properly with it's directory structure so I followed below link. copied header files .a file to the top of the directory in the 3rd party framework and
removed other folders.

I've been trying to make a Chartboost ANE as well, and I have the same problems as you.
First of all, it's easier to just use the headers and Chartboost static library directly in the Xcode project, instead of the Chartboost.framework. This way, your own .a file will include the Chartboost library, and you don't need to package it in the ANE. The resulting ANE will be smaller as well.
But whichever way you do it, the app will still crash. The error I get is the following:
<Error>: -[__NSCFString isEqualToNumber:]: unrecognized selector sent to instance 0x17802a4e0
This seems to be a problem with newer versions of the Chartboost SDK specifically. So for now I'm still using Chartboost 4.0 in my ANE. Unfortunately it doesn't contain some of the new features I'd like to use.
I've contacted Chartboost support about it. But they say they don't support AIR, and their SDK is working fine when used in a regular native app.
So somehow the combination of Chartboost and AIR is making it crash... If anyone has been able to get it working with the new Chartboost SDK, I would sure like to hear about it!
