Xcode 7 - 宏名称必须是标识符

Question

我已升级到Xcode 7,突然我的目标之一无法构建"宏名称必须是标识符"消息.这个目标的调试配置构建得很好,我可以在设备上运行它,但是不会构建发布配置.

该错误指向目标的.pch文件,但是同样的.pch文件对许多其他目标(包括那些已发布的目标)构建正常.

这是错误消息:

In file included from :334:
:4:10: error: macro name must be an identifier
#define  1
         ^
1 error generated.

这是.pch文件:

#import 

#ifndef __IPHONE_4_0
#warning "This project uses features only available in iOS SDK 4.0 and later."
#endif

#ifdef __OBJC__
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>
    #import "Enums.h"
#endif
#define APP ((AppDelegate *)[[UIApplication sharedApplication] delegate])

我已经尝试过清理和Xcode重启.

我会感激任何指示,我如何深入挖掘并找到问题所在.

问题在于-D=1编译命令中的命令行选项.您在构建设置中的某处可能存在错误值,可能是在预处理器宏或其他C标志中.
