ios - i386/armv7 架构的 undefined symbol [cocoapods]

Question

使用 $ pod install 命令安装自定义 pod 后，我无法构建项目，因为存在如下所示的一些错误(在我的 Xcode 上，错误是关于 armv7，在另一个 Xcode 上，错误是关于 i386 架构):

Undefined symbols for architecture armv7:
  "_generateCombMatrix", referenced from:
      -[className method:] in libPods-Bot-betting-core.a(ClassName)
  "_debugLog", referenced from:
  -[ClassName Method:] in libPods-Bot-betting-core.a(className.o)
  -[ClassName method] in libPods-Bot-betting-core.a(className.o)
  -[className method] in libPods-Bot-betting-core.a(className.o)
  -[className method:] in libPods-Bot-betting-core.a(className.o)
  -[className method:] in libPods-Bot-betting-core.a(className.o)
  -[className method] in libPods-Bot-betting-core.a(className.o)
  -[className method] in libPods-Bot-betting-core.a(className.o)
  -[className method] in libPods-Bot-betting-core.a(className.o)
  ...
  "_SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO", referenced from:
  -[className init] in libPods-Bot-betting-core.a(className.o)

错误中提到的文件位于项目 Pods 中，并且 libPods.a 库已正确链接到该项目。 这是调试时的 .xconfig 文件(发布时相同):

GCC_PREPROCESSOR_DEFINITIONS = $(inherited) COCOAPODS=1
HEADER_SEARCH_PATHS = "${PODS_ROOT}/Headers/Public" "${PODS_ROOT}/Headers/Public/betting-core"
OTHER_CFLAGS = $(inherited) -isystem "${PODS_ROOT}/Headers/Public" -isystem "${PODS_ROOT}/Headers/Public/betting-core"
OTHER_LDFLAGS = -ObjC -l"Pods-Bot-betting-core"
OTHER_LIBTOOLFLAGS = $(OTHER_LDFLAGS)
PODS_ROOT = ${SRCROOT}/Pods

该库支持该架构，如下面的屏幕所示:

今天也遇到了类似的问题。我通过删除所有派生数据解决了该问题:Windows -> 项目 -> 选择工作区 -> 单击右侧“派生数据”旁边的“删除...”。
