如何将预编译的头文件添加到ios项目中？ [英] How do I add a precompiled header file to my ios project?

问题描述

我正在寻找创建预编译的头文件，以避免在项目的每个头中包含相同的调试和跟踪库。

I'm looking to create a precompiled header file, to avoid having to include the same debug and tracking libraries in every header in the project.

我是创建了一个名为-Prefix.pch的文件：

I've created a file called -Prefix.pch:

#ifdef __OBJC__
#import "Blah.h"
#import "Blarg.h"
#endif

并将其添加到项目中。还有什么我应该做的，或者现在应该做些什么（假设我做一个项目干净并重新编译）？

and added it to the project. Is there anything more I'm supposed to do, or should things just work now (assuming I do a project clean and recompile)?

推荐答案

设置目标的构建设置如下：

Set the target's build settings as follows:

GCC_PRECOMPILE_PREFIX_HEADER=YES
GCC_PREFIX_HEADER="Prefix.pch"

请注意，如果您更喜欢使用Xcode的UI，可以在Build Settings搜索字段中填写这些键。你的构建设置。

Note that you can plop these keys in the Build Settings search field, if you prefer to use Xcode's UI for your build settings.
