YXY 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. then, I pop to last ViewController. Next, I push to next ViewController again, I get a crash error. I don't know how to solve this problem, I need your help. Thanks a lot.
