条件编译 - 检查方案 [英] Conditional Compilation - Check Scheme

问题描述

在我能够执行简单的编译器检查以查看正在运行的方案之前的Swift项目中，然后有条件地包含代码。例如：

In a Swift project before I've been able to perform a simple compiler check to see which scheme is running, then conditionally include code or not. For example:

#if MyScheme
    Add code here
#endif

但出于某种原因，在我的Objective-C项目中，这似乎不起作用。这应该以同样的方式工作吗？或者Swift编译器是否有一些允许这种行为的改进？

But for some reason, in my Objective-C project, this doesn't seem to be working. Should this work the same way? Or does the Swift compiler have some advancements which allow this kind of behaviour?

推荐答案

使用 #ifdef

//example for debug scheme
#ifdef NDEBUG
   Add code here
#endif

您可以在此处定义预处理器宏
