如何包括一个静态库并且它的#import路径仍然有效？ [英] How to include a static library and have its #import paths still be valid?

问题描述

假设我有一个使用以下文件结构创建的静态库：

Say I have a static library that was created with the following file structure:

• Folder1
  
  
  
  • File1.h
  
  
  
  
  • File2.h
  
  

  现在位于 File1.h ，它指的是没有路径的 File2.h （例如 #import File2.h ）。库成功构建。 （它不需要完整路径（即 #import Folder2 / File2.h ），因为这两个文件都是同一个项目的一部分。）

  Now inside of File1.h, it refers to File2.h without a path (e.g. #import File2.h). The library builds successfully. (It doesn't require the full path (i.e. #import Folder2/File2.h) because both files are part of the same project.)

  现在，当我将这个库包含在另一个项目中时， #import File2.h 语句不再编译，我必须将其更改为 #import Folder2 / File2.h （或类似的东西）。这意味着我必须修改原来的库，这是不好的。

  Now when I include this library in another project, that #import File2.h statement no longer compiles, and I have to change it to #import Folder2/File2.h (or something similar). This means that I have to modify the original library, which is not good.

  我得到的具体错误消息是：

  The specific error message I get is:

  
  

  File2.h：没有此类文件或目录

  File2.h: No such file or directory

  一个方法让它知道这两个文件应该是这个新项目的一部分，因为我看到的只有两个文件，我包括了 MyLib.xcodeproj 和 lixMyLib.a 。

  There doesn't seem to be a way to let it know that both files should be a part of this new project, since the only two files I see after I included the library are MyLib.xcodeproj and lixMyLib.a.

  我在我的新项目中添加静态库的方法是通过执行以下操作：

  The way I included the static library in my new project is by doing the following:

  
  
  1. 将 MyLib.xcodeproj 拖入我的新专案。
  
  
  2. 将 libMyLib.a 文件添加到我的新项目目标。
  
  
  3. 添加到标题搜索路径目录（包含 Folder1 和 Folder2 的文件夹）。
  
  
  1. Drag MyLib.xcodeproj into my new project.
  2. Add the libMyLib.a file to my new project's target.
  3. Add to the Header Search Paths a relative path to the home directory of my library (the folder that contains Folder1 and Folder2).
  
  
  

  有没有什么办法，我可以让它自动知道在哪里找到这些文件，因为它是在图书馆本身做的？我意识到我可以添加路径 Folder1 和 Folder2 到我的新项目的标题搜索路径，但我'寻找一个更好的方式，因为这两个文件夹只是一个例子，它可以很容易地50个文件夹，我需要包括。我正在寻找一个解决方案，如果可能，不需要我输入所有50个文件夹的路径。

  Is there any way I can have it automatically know where to find these files just as it was able to do in the library itself? I realize that I can probably add the paths Folder1 and Folder2 to the Header Search Paths of my new project, but I'm looking for a better way, since these two folders are just an example, and it could just as easily be 50 folders I would need to include. I'm looking for a solution which doesn't require me to type the paths to all 50 of those folders, if possible.

  推荐答案

  p>尝试检查所有这些标头的父文件夹路径旁边的递归复选框。

  Try checking the "Recursive" checkbox next to the path to the parent folder of all those headers.
