ios - Xcode 7 - 宏名称必须是标识符

Question

我已经升级到 Xcode 7，突然间我的一个目标无法构建并显示“宏名称必须是标识符”消息。此目标的调试配置构建正常，我可以在设备上运行它，但发布配置不构建。

错误指向目标的 .pch 文件，但相同的 .pch 文件构建对于许多其他目标来说都正常，包括那些已发布的目标。

这是错误信息:

In file included from :334:

#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。

对于如何深入挖掘并找到问题所在的任何指示，我将不胜感激。

问题出在编译命令中的 -D=1 命令行选项。您在build设置中的某处有一个错误的值，可能是在预处理器宏或其他 cflags中。
