在 Xcode 7 中发现了一个意外的 Mach-O 头代码:0x72613c21 [英] Found an unexpected Mach-O header code: 0x72613c21 in Xcode 7

问题描述

我有一个使用 ObjC 动态框架的 Swift 项目，该框架必须链接并嵌入到我的项目中.项目在设备上运行正常，提交到App Store时，验证时出现错误:发现意外的 Mach-O 头代码:0x72613c21

I have a Swift project that uses a ObjC dynamic framework, the framework had to be linked with and embedded into my project. The project runs OK in devices, when submitted to App Store, the error occurred during validation: Found an unexpected Mach-O header code: 0x72613c21

以下是验证日志:

如果我从项目的嵌入式框架部分删除动态框架，那么它可以通过验证，但是由于我的动态框架缺少图像，在设备中运行时会崩溃，知道吗?顺便说一句，动态框架禁用了bitcode，所以我的项目也禁用了bitcode，并且没有codesigned.

If I remove the dynamic framework from the project’s Embedded frameworks section, then it can pass the validation, but crashes when run in devices due to the missing image of my dynamic framework, any idea? BTW, dynamic framework has bitcode disabled, so my project also disables bitcode, and is not codesigned.

推荐答案

为每个框架检查两件事:

Check two things for every framework:

1. 框架的 Mach-O 类型(在框架目标的构建设置中)

1. 是否通过将框架放入构建阶段来复制框架 -> 嵌入框架(或 a.brooks hollar 提到的复制捆绑资源)

如果框架的 Mach-O 类型是静态库"，则不应该放在嵌入框架中；如果 Mach-O 类型是动态库"，它应该放在嵌入框架中.

If the Mach-O type of the framework is "static library", it should not be put in embed frameworks; if the Mach-O type is "dynamic library", it should be put in embed frameworks.

就我而言，它是我手动添加的 SocketRocket，它同时具有静态库目标和具有相同框架名称的动态库目标.删除静态库目标，只嵌入动态库框架后，问题消失.

In my case it was SocketRocket I added manually which has both a static library target and a dynamic library target with the same framework name. After deleting the static library target and only embed the dynamic library framework, the problem disappears.

注意:

如果您无权访问源项目，则可以使用以下方法手动检查它是动态框架还是静态框架:https://stackoverflow.com/a/32591983/308315

If you don't have access to the source project, you can manually check if it's a dynamic or static framework using this approach: https://stackoverflow.com/a/32591983/308315
