[Cocos2D-x] Skipping selector 'xxxxxxx' since no CCBSelectorResolver is present.

I knew that it is a old tool. Even though I had met this question. The whole callback methods defined in ccb are skipped as title. The problem is, in that ccb file, CCLayer, the representation of whole layer, which custom class text field I forgot to setup. If you are a newbie of CocosBuilder like me, you should check your ccb file's CCLayer custom class name in Cocosbuilder. The custom class is the name of the class you used in Xcode to represent that scene, so it is not a class such like CCLabel, CCButton...etc. though.
