我有一套数据类别,我想以我自己的方法,通过创造每个类别独有的类别来扩大。
在宣布某一类别时,每个类别都需要有独一无二的名称,或者我可以重新使用同一名称。
例。 Saye 我有一个名单类别和清单类别,我希望这两个类别都有。 我现在宣布:
In List+Additions.h
@interface List (Additions) ...
In ListItem+Addtions.h
@interface ListItem (Additions) ...
这难道吗? 我可以说,它是否一贯工作。 哪一个类别的名称? 它是“补充”,还是“ListItem+Additions”。
类别名称为<代码>List (Additions)和ListItem(Additions)。 因此,这两个类别是单独和独立的。
Something like "ListItem+Additions" is a common convention for the file names which define the categories, but neither the compiler nor the runtime pay any attention to that.
这难道吗? 我可以说,它是否一贯工作。 哪一个类别的名称? 它是“补充”,还是“ListItem+Additions”。
是的,它是ok的。
这两种类别都有相同的名称:Additions,但其中一类为Lists,另一类为。 ListItem s category. 因此,姓名没有冲突。 即使你将这两类声明放在同一档案中,情况也是如此。
