I'm building a Cocoa Touch Static Library. How should I decide whether to copy a header file as public, private, or project?

推荐答案

Public:界面已完成，旨在供您产品的客户使用.产品中包含一个公共标头作为可读源代码，没有任何限制.

Public: The interface is finalized and meant to be used by your product’s clients. A public header is included in the product as readable source code without restriction.

私有:该界面不适合您的客户，或者处于开发的早期阶段.产品中包含一个私有标头，但它被标记为私有".因此，这些符号对所有客户端都是可见的，但客户端应该明白他们不应该使用它们.

Private: The interface isn’t intended for your clients or it’s in early stages of development. A private header is included in the product, but it’s marked "private". Thus the symbols are visible to all clients, but clients should understand that they're not supposed to use them.

项目:该接口仅供当前项目中的实现文件使用.项目标头不包括在目标中，除了在目标代码中.客户根本看不到这些符号，只有您才能看到.

Project: The interface is for use only by implementation files in the current project. A project header is not included in the target, except in object code. The symbols are not visible to clients at all, only to you.
