我可以在另一个框架中包含一个框架吗?

问题描述

我正在编写一个框架(称为 Lighthouse.framework)，该框架又使用来自另一个框架(准确地说是 RegexKit.framework)的代码.我已将 RegexKit.framework 复制到我自己的框架中，使其具有如下结构:

I'm writing a framework (called Lighthouse.framework) that, in turn, uses code from another framework (RegexKit.framework, to be precise). I have copied RegexKit.framework into my own framework, so that it has a structure like the following:

Lighthouse.framework/
  Versions/
    A/
      Frameworks/
        RegexKit.framework
      Lighthouse

但是，当我尝试运行使用 Lighthouse.framework(我的框架)的应用程序时，我收到以下错误:

However, when I try to run an application that uses Lighthouse.framework (my framework), I get the following error:

dyld:库未加载:@executable_path/../Frameworks/RegexKit.framework/Versions/A/RegexKit

dyld: Library not loaded: @executable_path/../Frameworks/RegexKit.framework/Versions/A/RegexKit

Referenced from: /Users/mdippery/Developer/Projects/Current/lighthouse/build/Debug/Lighthouse.framework/Versions/A/Lighthouse

原因:图片未找到

显然，加载程序没有找到 RegexKit.

Obviously, the loader isn't finding RegexKit.

这是加载器期望加载的路径，由 otool 提供:

Here're the paths the loader expects to load, courtesy otool:

build/Debug/Lighthouse.framework/Versions/A/Lighthouse:
    /Users/mdippery/Library/Frameworks/Lighthouse.framework/Versions/A/Lighthouse (compatibility version 1.0.0, current version 1.0.0)
    /System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 12.0.0)
    @executable_path/../Frameworks/RegexKit.framework/Versions/A/RegexKit (compatibility version 0.4.0, current version 0.6.0)
    /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.4)
    /usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 227.0.0)
    /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 476.19.0)
    /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 677.26.0)

我可以在另一个框架中包含一个框架吗?这是正确的方法吗?如何解决我的错误?

Can I include a framework in another framework? Is this the proper way to do it? How can I resolve my error?

推荐答案

我找到了解决这个问题的方法.我从 sbooth 的回答中吸收了一些想法，但修复更简单.我运行了这个脚本:

I discovered a fix for this problem. I incorporated some ideas from sbooth's answer, but the fix was simpler. I ran this script:

install_name_tool -change @executable_path/../Frameworks/RegexKit.framework/Versions/A/RegexKit @loader_path/Frameworks/RegexKit.framework/Versions/A/RegexKit "${TARGET_BUILD_DIR}/${PRODUCT_NAME}.framework/Versions/A/${PRODUCT_NAME}"

作为运行构建脚本阶段.

as a Run Build Script phase.

注意，对于一般情况，您必须将@executable_path/../更改为@loader_path/，一切正常.

Note that, for the general case, you have to change @executable_path/../ to @loader_path/, and all is well.
