Xcode 7 bitcode_strip 错误

Xcode 7 bitcode_strip error

提问by pzs7602

My Xcode 7 beta3 project includes some framework compiled by Xcode 6, these frameworks are imported to my project by Embeded Frameworks option in "Build Phase" tab. Because these frameworks does not support bitcode, so the "Enable Bitcode" option turned to NO, when compile the project, Bitcode_strip error occurred:

我的 Xcode 7 beta3 项目包括一些由 Xcode 6 编译的框架，这些框架通过“Build Phase”选项卡中的 Embeded Frameworks 选项导入到我的项目中。因为这些框架不支持bitcode，所以“Enable Bitcode”选项变成NO，编译项目时，出现Bitcode_strip错误：

I found that the error happened when Xcode copy my frameworks to my App package and try to strip bitcode from the framework, but these frameworks were compiled by Xcode early version and did not include bitcode at all. How to fix this? Thanks!

我发现当Xcode将我的框架复制到我的App包并尝试从框架中剥离bitcode时发生了错误，但是这些框架是由Xcode早期版本编译的，根本不包含bitcode。如何解决这个问题？谢谢！

As I found out, XCode uses bitcode-strip only when enviroment variable STRIP_BITCODE_FROM_COPIED_FILES is set to YES. It seems that it's set to YES by default when enable_bitcode is switched on.

正如我发现的那样，XCode 仅在环境变量 STRIP_BITCODE_FROM_COPIED_FILES 设置为 YES 时才使用 bitcode-strip。似乎在启用 enable_bitcode 时默认设置为 YES。

Adding User-Defined Setting STRIP_BITCODE_FROM_COPIED_FILES=NO to your Target can help you, XCode will not use bitcode-strip, but your app which will use frameworks without bitcode section probably will not work. So it's better to recompile them also using STRIP_BITCODE_FROM_COPIED_FILES=NO if necessary.

将用户定义的设置 STRIP_BITCODE_FROM_COPIED_FILES=NO 添加到您的目标可以帮助您，XCode 不会使用 bitcode-strip，但您的应用程序将使用没有 bitcode 部分的框架可能无法运行。因此，如有必要，最好也使用 STRIP_BITCODE_FROM_COPIED_FILES=NO 重新编译它们。

Tested on XCode 7 beta 5

following up on M. Pogosskiy's answer, it took me awhile to track down where to put the STRIP_BITCODE_FROM_COPIED_FILES bit setting (not too familiar with these). for reference, here's an illustration:

跟进 M. Pogosskiy 的回答，我花了一段时间才找到放置 STRIP_BITCODE_FROM_COPIED_FILES 位设置的位置（对这些不太熟悉）。作为参考，这是一个插图：
