在编译时不包含Prefix.pch [英] Prefix.pch not included at compilation time

问题描述

我在GlobalVar.h和其他.h文件中定义了许多常量.我将这些文件导入到Prefix.pch文件中，如下所示:

I have defined many constants in GlobalVar.h and other .h files. I import these files in the Prefix.pch file like this :

//
// Prefix header for all source files of the 'XXX' target in the 'XXX' project
//

#import "GlobalVar.h"
[...]

#ifndef __IPHONE_3_0
#warning "This project uses features only available in iPhone SDK 3.0 and later."
#endif

#ifdef __OBJC__
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>
    #import <CoreData/CoreData.h>
#endif

但是当我编译项目时，所有#defined标识符都丢失了，并报告为使用未声明的标识符XXX".

But when I compile the project all the #defined identifiers are missing and reported as "Use of undeclared identifier XXX".

我在Build设置中进行了搜索，并将PCH文件设置为"Prefix Header" ...我在Base SDK 4.3和XCode 4.0.2上

I searched in the Build settings and the PCH file is set as "Prefix Header"... I am on Base SDK 4.3 and XCode 4.0.2

您是否有调试建议?

感谢您的帮助

推荐答案

在清理 DerivedData 并重新启动Xcode之后，我仍然遇到此错误.希望能对您有所帮助.

I came across this error yet, after cleaning DerivedData and restart Xcode I fix it. Hope to help.
