I have some ideas for doing some tricky stuff with metaclasses in future library versions, and i might even work in properties and slots 对于未来库版本中的元类,我有几个技巧方面的想法,而且我甚至可能使用特性和插槽。
Once we intro ? duce metaclasses, we can finally declare the selector for a dynamically linked method where it belongs : in the same interface file as the metaclass pointer 一旦引入元类,我们终于能在元类指针所在的同一接口头文件里声明动态连接方法专有的选择器。
