Xcode 4.2: How to import .h file from subproject
提问by Shameem
I am new to Xcode subprojects. In my iPhone app project MyProject, I am trying to refactor some common code to a static library project called MyLibrary. After I create MyLibraryand move the code, MyProjectis no-longer compiling. The error is that the MyProjectcannot see the .h files in MyLibrary.
我是 Xcode 子项目的新手。在我的 iPhone 应用程序项目中MyProject，我试图将一些通用代码重构为一个名为MyLibrary. 在我创建MyLibrary并移动代码后，MyProject不再编译。错误是MyProject无法在 .h 文件中看到 .h 文件MyLibrary。
The error MyLibraryConfig.h: No such file or directoryis coming in the line:
错误MyLibraryConfig.h: No such file or directory即将出现：
#import "MyLibraryConfig.h"
- How to import the
MyLibrary.h files inMyProject? - What is the best practice here? Assuming I have multiple such libraries, it is tedious to add these to header search paths to the parent project.
- 如何导入
MyLibrary.h 文件MyProject？ - 这里的最佳做法是什么？假设我有多个这样的库，将它们添加到父项目的头搜索路径是很乏味的。

Maybe your header file is also in a subdirectory.
也许你的头文件也在一个子目录中。
Imagine the following directory setup:
想象以下目录设置：
- Desktop
- MyProject
- MyProject.xcodeproj
- main.m
- MyLibrary
- MyLibrary.xcodeproj
- MyHeaderFile.h <-- wanted header file
If main.mhas these contents:
如果main.m有这些内容：
#include "MyHeaderFile.h"
int main() {
return 0;
}
The compiler (gcc) will think that MyHeaderFile.his located in the same directory as main.m, from which it is included. To tell the compiler you mean the header file in a subfolder, you have can do two things.
编译器 (gcc) 会认为MyHeaderFile.h与包含它的main.m位于同一目录中。要告诉编译器您的意思是子文件夹中的头文件，您可以做两件事。
- You can add a directory to the gcc compiler that says: "hey, also look in that folder". You can do this by using the
-iquote myFolderflag. - You can include the directory in the include-statement:
#include "MyLibrary/MyHeaderFile.h"
- 您可以向 gcc 编译器添加一个目录，上面写着：“嘿，也请查看该文件夹”。您可以通过使用
-iquote myFolder标志来做到这一点。 - 您可以在包含语句中包含目录：
#include "MyLibrary/MyHeaderFile.h"
There could of course be another problem, but this seams like the most straightforward one.
当然可能还有另一个问题，但这似乎是最直接的问题。

In build settings --> Header Search Path --> Add below entry
在构建设置--> 标题搜索路径--> 添加以下条目
$(SRCROOT) and mark it as recursive.
$(SRCROOT) 并将其标记为递归。
