您也可以使用xcodebuild命令搭配**-showBuildSettings**参数，从命令列取得此信息：

$ xcodebuild -project myProj.xcodeproj -target "myTarg" -showBuildSettings

这将把一个类似上面所示的列表转储到标准输出中。

虽然@dunedin15的奇妙回答在很多情况下都很好地为我服务，但它在某些边缘情况下会给予不准确的结果，* 例如在调试Archive构建的静态库的构建设置时 *。
作为一种替代方法，可以在构建运行脚本构建阶段时将其轻松添加到任何目标的“日志构建设置”中：

• 选择所述目标后，在“Build Phases”选项卡下：*
• 要进行添加，请单击“Target Dependencies”部分左上方的小“+”按钮，并将shell设置为/bin/bash，将命令设置为export。
• 您可能还希望将该阶段向上拖动，以便它刚好发生在Target Dependencies之后、Copy Headers或Compile Sources之前。
• 将该阶段从“运行脚本”重命名为“日志构建设置”并不是一个坏主意。

其结果是生成了一个非常有用的当前环境变量列表，这些变量用于构建：

苹果的“构建设置参考”文档中有什么正式的文档（或者如rjstelling的答案所示，在构建脚本中使用 env 来查看Xcode实际传递给你的是什么。
如果上述链接发生变化，请在Google上搜索：“构建设置参考”站点：developer.apple.com

上面已经回答了这个问题，但我想提出一个替代方案。
在项目或目标的“生成设置”中，可以转到“编辑器”菜单并从菜单中选择“Show Setting Names”。这会将“生成设置”窗格中的所有选项更改为生成变量名称。菜单中的选项将更改为“Show Setting Titles”，选择此选项可更改回原始视图。
如果您知道要在脚本中使用的构建设置，在菜单中切换设置名称，并且可以看到变量名称，则这会很方便。

在Xcode 4或更早版本中，在运行脚本构建阶段有一个选项“Show environment variables in build phase”（在构建阶段显示环境变量）。如果选中此选项，则会在构建日志中以橄榄绿色背景显示。

如果您想在runtime中使用代码读取/检查您的Target Build Settings，方法如下：
1)添加Run Script：

cp ${PROJECT_FILE_PATH}/project.pbxproj ${CONFIGURATION_BUILD_DIR}/${EXECUTABLE_NAME}.app/BuildSetting.pbxproj

它会将Target Build Settings文件复制到您的Main Bundle（将被称为BuildSetting.pbxproj）。
2)现在，您可以随时在代码中检查该文件的内容：

NSString *thePathString = [[NSBundle mainBundle] pathForResource:@"BuildSetting" ofType:@"pbxproj"];
NSDictionary *theDictionary = [NSDictionary dictionaryWithContentsOfFile:thePathString];
