这个示例代码中,一个SuperClass实现了+(void)load和+(void)initialize方法(实际上应该算是重写覆盖了NSObject的这两个方法);ChildClass继承于SuperClass,但是只重写+(void)initialize没有+(void)load;Insideinitialize类也有+(void)load和+(void)initialize方法,它在ChildClass的i+(void)initialize方法中被构建出一个...
In a custom implementation ofloadyou can therefore safely message other unrelated classes from the same image, but anyloadmethods implemented by those classes may not have run yet. Apple的文档很清楚地说明了initialize和load的区别在于:load是只要类所在文件被引用就会被调用,而initialize是在类或者其子类的...
