Xcode 7 - 宏名称必须是一个标识符

我已经升级到Xcode 7，并突然出现一个目标未能建立与“宏名称必须是标识符”消息。这个目标的调试配置可以正常工作，我可以在设备上运行它，但发布配置不会生成。Xcode 7 - 宏名称必须是一个标识符

错误指向目标的.pch文件，但对于许多其他目标（包括那些正在发布的目标），相同的.pch文件可以正常生成。

以下是错误消息：

这里是.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 &ltUIKit/UIKit.h> 
    #import &ltFoundation/Foundation.h> 
    #import "Enums.h" 
#endif 
#define APP ((AppDelegate *)[[UIApplication sharedApplication] delegate])

我已经尝试过的干净和Xcode的重新启动。

我会很感激任何指针，我该如何深入挖掘并找到问题所在。

我有类似的问题，它是用于枚举。你可以用enums.h的枚举来更新你的问题吗？ – Miknash

我删除了“Enums.h”行，仍然存在相同的问题。那应该是别的东西。我会分享“Enums.h”，但它很大。试图同时在项目的git历史中找到任何东西... –

问题出在编译命令中的-D=1命令行选项。在构建设置中某处可能存在一个错误值，可能是在预处理器宏或其他C标志中。

这就是它！非常感谢。我不小心重新访问了Xcode中的预处理器宏，并且对于发布配置，我只设置了一个空间：TAXI（空间）= 1，它在Xcode，TAXI和= 1中创建了多个宏。因此，-D = 1。谢谢你的鹰锐利的眼睛和智慧！ –

无论您在.pch文件中显示的内容看起来不错，它会为我正确编译。然而，编译器抱怨下面的代码没有为宏指定名称。 #define必须后跟宏名称，而在您的声明中它是缺少的。您能否在您的代码库中搜索#define 1声明并更正它。

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

作为一个侧面说明，请确保你没有任何预处理器的值设置为APP像APP设置为1。要排除，请尝试使用与APP不同的变量。
