Hi , guys.
I have just meet a problem about 'EXC_BAD_ACCESS'. The 'CCDirector.shared().startAnimation()' method is used to start a animation of scene.
First, I push to next ViewController, I add a scene on a subview, It's normal.
then, I pop to last ViewController.
Next, I push to next ViewController again, I get a crash error.


Here is my judge method.

It is my demo link. https://github.com/sandart/SpineDemo.git
I don't know how to solve this problem, I need your help.
Thanks a lot.
