Estimote SDK 的未定义符号链接器失败

Question

我正在尝试将 Estimote SDK 3.0 包含到我的项目中，但出现以下链接错误：

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_ESTBeaconRegionWrapper", referenced from:
      objc-class-ref in EstimoteSDK(ESTSecureBeaconManager.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我已将框架添加到 'Build phase' 并检查框架搜索目录设置是否包含该目录。

我从 Estimote 下载了示例应用程序，它使用相同的框架（这是我从中复制的）并且构建良好。我看不出任何明显的区别。

我怎样才能找出问题所在？

编辑：我正在使用 Xcode 6.2。我正在构建 iPhone 6（表示架构 arm64、armv7、armv7s）。在我为 armv7s 构建下面的问题之后，我得到了同样的错误（对于 armv7s）。所以一定是框架链接有问题

编辑 2：我删除了 -ObjC 'Other linker flag'，因为将其添加到 Estimote 项目会产生相同的错误。但是现在我得到了更多的错误：

[编辑 3：] 添加 Security.framework 似乎又迈出了一步：

Answer 1

我刚下载 https://github.com/Estimote/iOS-SDK 他们的 SDK 并成功将其包含在示例项目中。

在“Build Settings”下的“Build Active Architecture Only”设置 'Debug' 到 YES

也试试在 'General' 个选项卡中

在'Link Frameworks and Libraries'下添加框架。
在'Embedded Binaries'下添加框架。

确保 EstimoteSDK.framework 确实存在于其原始位置，您可能不小心删除了它。

Answer 2

查看 podspec，它指定要添加到 OTHER_LDFLAGS 的 -lc++ 标志。如果您没有设置此标志，可能会导致此类问题。

Answer 3

感谢上面的各种提示，我检查了整个构建文件，并找到了不同的标志。它是 'Enable Modules'，并在我的构建设置中设置为 'No'。

Answer 4

此问题已在 Estimote SDK 3.0.2 中修复！ (:
