如何在 IOS 上将 Boost 与 Cocoapods 一起使用？
How to use Boost with Cocoapods on IOS?
有没有人成功将 Cocoapods 与 Boost pod 一起使用？
我不明白它似乎没有完全安装。在 pod 安装到一个空白项目后，我得到以下信息。有没有我遗漏的步骤？
这是我安装的输出
pod 安装 --verbose

为什么没有列出 Pod？
这是 boost 的产物，不是 Xcode 项目，只是一组文件。此外，您会发现 boost 内部目录位于 ${PODS_ROOT}/boost 中，在 Build Settings[=] 的 Header Search Path 中引用71=]。这就是您使用 Pod 的收获。
Pod 和 Boost 层次结构
需要在 ../Pods/boost/boost 中嵌套 boost 以允许库中的文件引用自身，如：
#include "boost/date_time/posix_time/posix_time_config.hpp"
如果让操作完成：（boost 库在压缩后超过 100 MB）

...虽然您在项目中看不到它，但您会发现它在源代码树中：
你可以参考一下：
#import "boost/date_time.hpp"
并开始处理其他紧迫的问题，例如定位 #include <cstdlib>，这完全是另一个话题。
Objective-C++编译
为了编译 boost，这是一个 C++ 库，您需要从 C++ 中明确引用它源文件（不是 C 来源，它们是 .m 中的默认设置），或者采用 compiling a C++ class in Xcode: error during compilation: stl vector.
中列出的替代解决方案
从 .mm 文件中，包括以下两个测试行：
#include <cstdlib> // Proof of concept
#import "boost/date_time.hpp"
为了这个例子，我将 main.m 重命名为 main.mm。
由于 Pod 没有导入任何 .ipp 文件，您可以在 Preprocessor Macros 中添加 NO_BOOST_DATE_TIME_INLINE=1 在 Build Settings。这样做，您将收到大约一打警告，如下所示，并且编译成功，无需手动导入。
