如何在Swift框架中导入私有框架头文件？ [英] How to import private framework headers in a Swift framework?

问题描述

我有一个Objective-C框架（框架A），暴露一些公共和一些私有头。公共头部也在框架的伞头中声明。我有一个与Objective-C框架链接的第二个Swift框架（框架B）。

现在，如果我想导入A的公共头部做一个 import A 。

但是如何导入私有头？

我知道桥接头不是一个选项，因为不支持框架。我需要以某种方式为私有头创建一个单独的伞头吗？

解决方案

你需要修改框架 A ，以便导出私有模块。

1. 创建 A 项目中的http://clang.llvm.org/docs/Modules.html#private-module-map-files\">私有模块映射文件。这将是这样：

   
   
   

   A / private.modulemap ：

    显式模块A.Private {
    
    //这是你的私有头文件的列表。 
    headerPrivate1.h
    headerPrivate2.h
    
    export * 
   } 
     




2. 在框架 A 目标的Build Settings中，搜索Private Module Map File并使其：

     $（SRCROOT）/A/private.modulemap 
     




3. 不要在编译源中包含 private.modulemap 文件。这会导致不必要的警告。




4. 清洁和构建框架 A >
   

5. 在框架B Swift文件中。您可以像这样导入私有模块：

     import A 
    import A.Private 
     

I have an Objective-C framework (framework A) that exposes some public and some private headers. The public headers are also declared in the framework's umbrella header. I have a second Swift framework (framework B) that links with the Objective-C framework.

Now, if I want to import the public headers of A in B I simply need to do an import A.

But how do I go about importing the private headers?

I know a bridging header is not an option since that's not supported for frameworks. Do I need to somehow create a separate umbrella header for the private headers?

解决方案

You need to modify framework A, So that it export a private module.

1. Create a private module map file in A project. This would be something like this:

   A/private.modulemap:

   explicit module A.Private {
   
       // Here is the list of your private headers.
       header "Private1.h"
       header "Private2.h"
   
       export *
   }
   

2. In the "Build Settings" of framework A target, search "Private Module Map File" line, and make that:

   $(SRCROOT)/A/private.modulemap
   

3. Do not include private.modulemap file in "Compile Sources". That causes unnecessary warnings.

4. Clean and Build framework A target.

5. In framework B Swift files. you can import the private module like this:

   import A
   import A.Private
