Cocoa Pods 在调试模式下运行时无法链接库？

Question

我正在使用pods 链接AfNetworking、facebook 等库，它在release 模式下运行良好，但我想通过调试检查变量值，但它在发布模式下显示所有变量 nil .我尝试通过编辑架构以debug 模式运行，但编译失败，显示各种库未找到错误。

编辑我已经尝试更新架构.....但这无济于事。 调试模式下的错误日志

Answer 1

如果上述答案对您不起作用，则问题可能出在您安装 pod 时。检查你在运行pod install时是否有这样的消息

ProjectName [Release] 目标覆盖了在 `Pods/Target Support Files/ProjectName/Pods-ProjectName.release.xcconfig' 中定义的 OTHER_LDFLAGS 构建设置。这可能会导致 CocoaPods 安装出现问题

或类似的消息，但使用debug 而不是释放（或两者）。 如果是这样，请在 Xcode 中删除工作区中的 pod 项目，然后按照这个问题的答案The target ... overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Pods.xcconfig，我在这里过去了：

这在大多数情况下肯定有效：

转到您的目标构建设置 -> 其他链接器标志 -> 双击 .将 $(inherited) 添加到新行。

然后再次运行pod install。它为我做到了。

Answer 2

这意味着您使用的静态库不支持 x86_64 架构，
所以

1. 为“Pods”目标打开“构建设置”，并添加“x86_64”架构（在“架构”和“有效架构”部分）。
2. 将“仅构建活动架构”设置为“否”。
3. 清理“Pods”目标。
4. 构建您的目标。

Answer 3

删除 /Users/YourName/Library/Developer/Xcode/DerivedData/YourProject/Build/Products/Debug-iphoneos 中的 .a 文件。然后清理并构建。这对我有帮助。

Answer 4

对我有用的是将 $(inherited) 添加到：

• OTHER_LDFLAGS
• OTHER_CFLAGS
• FRAMEWORK_SEARCH_PATHS
• GCC_PREPROCESSOR_DEFINITIONS

提示：内部构建设置 ->（搜索栏）-> 在上方输入选项并添加 $(inherited)

Answer 5

我删除了 .a 文件，它对我不起作用，但是当我删除 /Users/YourName/Library/Developer/Xcode/DerivedData/YourProject 中的项目文件夹时。 这对我有帮助。
