如何在#ifdef 中编写if 条件。用于分期。在 Objective-C 中

我需要在此调用中添加一个条件暂存..

如何在这种情况下执行此操作。

  #ifdef MYAPP_PRODUCTION
        buildMode = @"Production";
    #else

    #ifdef MYAPP_RELEASE
        buildMode = @"Release";
    #else MYAPP_DEBUG
       buildMode = @"Debug";
    #endif
    #endif

另一个是 MyApp_Staging 需要在此 if 条件中包含如何做到这一点？

  #ifdef MYAPP_PRODUCTION
        buildMode = @"Production";
    #else

        buildMode = @"Release";
    #else MYAPP_DEBUG

您可以执行类似的操作来包含所有不同的选项，包括新的暂存模式，并使整个语句更清晰：

#ifdef MYAPP_PRODUCTION
    buildMode = @"Production";
#elif MYAPP_RELEASE
    buildMode = @"Release";
#elif MYAPP_DEBUG
    buildMode = @"Debug";
#elif MYAPP_STAGING
    buildMode = @"Staging";
#endif

You could do something like this to contain all the different options including the new Staging Mode and make the whole statement cleaner:

#ifdef MYAPP_PRODUCTION
    buildMode = @"Production";
#elif MYAPP_RELEASE
    buildMode = @"Release";
#elif MYAPP_DEBUG
    buildMode = @"Debug";
#elif MYAPP_STAGING
    buildMode = @"Staging";
#endif

你的问题不是很清楚......如果你想在 #ifdef 中使用多个条件，这里有一个解决方案：

#if defined(MYAPP_RELEASE) && defined(MyApp_Staging)
    // ...
#else
    // ...
#endif

Your question is not very clear... If you want multiple conditions in a #ifdef, here is a solution:

#if defined(MYAPP_RELEASE) && defined(MyApp_Staging)
    // ...
#else
    // ...
#endif

在 Swift 和 Xcode 7 中，语法发生了变化：

#if DEBUG || RELEASE
    let URL = "https://www.example.com/beta"
#elseif APPSTORE
    let URL = "https://www.example.com/prod"
#endif

In Swift and Xcode 7, the syntax has changed:

#if DEBUG || RELEASE
    let URL = "https://www.example.com/beta"
#elseif APPSTORE
    let URL = "https://www.example.com/prod"
#endif

如果您想用 2 个构建目标来否定条件，请像这样使用。

#if !(TOWNTALK || EPISD)

这又如何呢？

#if defined(MYAPP_PRODUCTION)
  buildMode = @"Production";
#elif defined(MYAPP_RELEASE)
  buildMode = @"Release";
#elif defined(MYAPP_DEBUG)
  buildMode = @"Debug";
//#elif defined(MYAPP_STAGING)
#else
  buildMode = @"Staging";  
#endif

What about this?

#if defined(MYAPP_PRODUCTION)
  buildMode = @"Production";
#elif defined(MYAPP_RELEASE)
  buildMode = @"Release";
#elif defined(MYAPP_DEBUG)
  buildMode = @"Debug";
//#elif defined(MYAPP_STAGING)
#else
  buildMode = @"Staging";  
#endif
