为什么我的DEBUG预处理器宏不被识别为objective-c

Question

我接手了一个有几个构建方案的项目：演示，发布，调试和生产。 整个代码..有几个预处理器宏if语句即

#ifdef DEMO
static NSString *const URL_SMART_TAXI      = @"http://demo.theapp.com";
#elif  PRODUCTION
static NSString *const URL_SMART_TAXI      = @"http://prod.theapp.com";
#elif  DEBUG
static NSString *const URL_SMART_TAXI      = @"http://localhost:8000";
#else
static NSString *const URL_SMART_TAXI      = @"http://dev.theapp.com";
#endif

出于某种原因，当我使用演示方案或生产方案构建时，这总是有效...但它只是不适用于调试 （每当我更改方案并运行调试时...它总是跳过调试并且去对于外卡选项）..

我看了整个项目，我没有看到任何针对演示或生产的特殊处理没有给出调试。

如果我运行grep -nri %environment% *这就是结果：

grep -nri production *

有任何想法吗？

更新： +构建设置的相关部分

Answer 1

这是因为你在做“ #elif ”，这是不一样的东西“ #elifdef ”（如果这样的事情存在）。

您应该同时定义PRODUCTION，DEBUG和DEMO，但只将一个设置为“ 1 ”，将其他设置为“ 0 ”。
