至于库，我只是将它拖到 Xcode 项目并将其设置为引用库而不是复制。

Here are the steps before adding a header file test.h in your project. Here is the files location root -> Library -> include -> test.h
以下是在项目中添加头文件 test.h 之前的步骤。这是文件位置 root -> Library -> include -> test.h
click on build settings
Find User Header Search path. add your header file location here. add following value to Debug, Release and Any Architecture field. $(SRCROOT)/Library/include. Your project Root is the folder that contains your project, it conatins .xcodeproj file.
点击构建设置
查找用户标题搜索路径。在此处添加您的头文件位置。将以下值添加到 Debug、Release 和 Any Architecture 字段。$(SRCROOT)/图书馆/包括。您的项目根目录是包含您的项目的文件夹，它包含 .xcodeproj 文件。
After adding path you will be able to add header in like this
添加路径后，您将能够像这样添加标题
# include "test.h"

You can drag them both the .a and .h files to Xcode, but make sure to not check the "Copy items to project folder". As for referencing the header file, you'll need to put it in a place where you can add a path to it in your #include/#import statements. Is there a reason you don't want to copy the header to your project file?
您可以将它们的 .a 和 .h 文件拖到 Xcode，但请确保不要选中“将项目复制到项目文件夹”。至于引用头文件，您需要将它放在可以在#include/#import 语句中添加路径的地方。您是否有理由不想将标题复制到您的项目文件中？
