ios - 为什么我的 DEBUG 预处理器宏没有被识别 objective-c

Question

我接手了一个项目，该项目有多种构建方案: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..它总是跳过调试并选择通配符选项)..

我查看了整个项目，没有看到任何针对调试的演示或生产给予的特殊处理。

如果我运行 grep -nri %environment% * 结果如下:

grep -nri production *

有什么想法吗？

更新: + build设置的相关部分

Answer 1

这是因为您正在执行“#elif”，它不是与“#elifdef”(如果存在这样的事情)。

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”。
