I want to use spin-Cocos2D-objc to display spine animation on iPhone. The demo using Objective-C developed by a third party provided on the website is 8 years old, so there are some problems in using it. I hope the official website can update the third-party link provided. The following problems occurred in my own attempts at integration:
I have just meet a problem about 'EXC_BAD_ACCESS'.
First, I push to next ViewController, I add a scene on a subview, It's normal.
