如何在IOS上使用Cocoapods的Boost？

Question

有沒有人成功地在Boost pod上使用Cocoapods？

我不明白它似乎並沒有完全安裝。在pod安裝到一個空白項目後，我會看到下面的內容。有沒有我失蹤的一步？

這是我的輸出裝

Answer 1

爲什麼沒有列出波德？

這是一個boost的神器，它不是一個Xcode項目，只是一組文件。另外，你會發現內部目錄boost正確地位於${PODS_ROOT}/boost的內部，引用於標題搜索路徑的構建設置。這是你使用Pod獲得的。

波德&升壓層次

的boost在../Pods/boost/boost嵌套需要允許在庫中的文件稱自己爲：

#include "boost/date_time/posix_time/posix_time_config.hpp" 

如果讓操作完成：（該boost庫壓縮時大小超過100 MB）

... while y OU沒有看到它在你的項目，你會發現它是在源代碼樹：

你可以引用它：

#import "boost/date_time.hpp" 

，並開始處理其他緊迫問題，如定位#include <cstdlib>，這完全是另一個話題。

的Objective-C++編譯

爲了編譯boost，這是一個C++庫，你需要從C++源文件（不ç來源，這是默認明確提到它在.m中），或採用compiling a C++ class in Xcode: error during compilation: stl vector中列出的替代解決方案。

從.mm文件，包括這兩個測試線：

#include <cstdlib> // Proof of concept 
#import "boost/date_time.hpp" 

對於此示例的目的，我已更名main.m成main.mm。 由於Pod沒有進口任何.ipp文件，你可以在預處理宏在構建設置添加NO_BOOST_DATE_TIME_INLINE=1。這樣做，您將獲得大約十幾個警告，如下所示，並且成功完成編譯，而無需手動導入。
