iphone：通过代码在Target的设置中获取User Defined变量？ [英] iphone: get User Defined variable in Target's setting by code?

问题描述

我的项目有多个目标。每个目标都有自己的 Class 文件，用于设置内容。我想在目标设置（ Info.plist 或Target的建筑设置）中存储 Class 名称。因此，我可以根据此设置定义我需要在每个目标中使用哪个类。

My project have multi-targets. Each target has its own Class file for setting stuff. I want to store that Class name in a target setting (Info.plist or Target's Building setting). So that I can define which class I need to use in each target based on this setting.

根据这个问题，我把一个特定于目标的用户定义的变量在每个Target的建筑设置中。

According to this question, I put "a target-specific User Defined variable" in each Target's Building Setting.

但是不知道如何在我的代码中找回它？

But don't know how to get it back in my code?

推荐答案

由于Info.plist文件也经过预处理，您可以使用以下方法：

As the Info.plist file is preprocessed too, you can use this approach:

为示例CLASS_NAME定义构建设置中的用户定义设置。
和Info.plist文件的关键字。将密钥命名为CLASS_NAME，并将值设置为 $ {CLASS_NAME} 。

Define a User defined setting in your build settings, for Example CLASS_NAME. And a key to your Info.plist-file. Name the key CLASS_NAME and set the value to ${CLASS_NAME}.

然后，您可以通过以下方式访问此设置：

You can then access this setting by:

NSString* className = [[[NSBundle mainBundle] infoDictionary] valueForKey:@"CLASS_NAME"];
