推荐答案

关于如何将版本号编码到静态库中没有共同的主题.

There is no common theme on how to encode a version number into a static library.

有时根本不存在.有时这是使用属于该库的标头完成的.有时它是使用返回此类信息的函数完成的.在某些情况下，静态库是伪框架的一部分，该框架包含一个可能包含正确版本号的 plist.

Sometimes there is none present at all. Sometimes that is done using a header that belongs to that library. Sometimes it is done using a function that returns such information. In some cases that static library is part of a pseudo framework which contains a plist that might contain a correct version number.

请记住，静态库本身只不过是放入文件存档中的一堆目标文件.几乎没有任何附加信息，更不用说元数据了.

Remember, a static library by itself is not much more than a bunch of object files put into a file archive. There is hardly any additional information, not to speak of metadata.
