Where to set environment variables for app?
提问by jww
I'm working with source code that is frozen and cannot be changed; but its ENV aware and expects changes through the ENV. The source code is being used in an Xcode 4/iOS project.
我正在使用冻结且无法更改的源代码；但它的 ENV 意识到并期望通过 ENV 进行更改。源代码正在 Xcode 4/iOS 项目中使用。
Xcode 3 allowed us to set environmental variables on the app in the Executable folder (see Figure 1 at iOS Debugging Magic). Xcode 4 appears to lack the 'executable info' that was present in Xcode 3.
Xcode 3 允许我们在 Executable 文件夹中的应用程序上设置环境变量（参见iOS Debugging Magic 中的图 1 ）。Xcode 4 似乎缺少 Xcode 3 中存在的“可执行信息”。
I've looked through a number of similar questions on Stack Overflow, but no one has answered the questions. Answers usually degenerate to preprocessor macros. Confer: How to set environment variables in iPhone executable using XCode 4?, Conditional Environment Variables in Xcode, and Where to set environmental variables in ios?.
我在 Stack Overflow 上浏览了许多类似的问题，但没有人回答这些问题。答案通常退化为预处理器宏。授予：如何使用 XCode 4 在 iPhone 可执行文件中设置环境变量？, Xcode 中的条件环境变量，以及ios 中在哪里设置环境变量？。

You can set environment variables via Xcode Schemes. To edit a scheme, select it in the top bar:
您可以通过 Xcode Schemes 设置环境变量。要编辑方案，请在顶部栏中选择它：
Choose the Run mode and go to the Arguments tab, and there you go...
选择 Run 模式并转到 Arguments 选项卡，然后就可以了...
By default, these settings are also used for the Test and Profile modes.
默认情况下，这些设置也用于测试和配置文件模式。
