在Objective-C中"@public"是什么意思? [英] What does “@public” mean in Objective-C?

问题描述

在阅读了关于@private的问题之后，我知道了作品.但是，由于所有变量默认都为@protected，并且您不能在不定义访问器的情况下真正访问变量，所以@public到底是做什么的?您什么时候使用它?

After reading a question on @private I understand how that works. However, since all variables default to @protected and you cannot really access a variable without defining an accessor, what exactly does @public do? When would you use it?

推荐答案

何时使用?需要时为public.要从该类外部访问它(没有任何额外的访问器)，就是这样. :)

When would you use it? When you need it to be public. To access it from outside that class (without any extra accessors), that is. :)
