推荐答案

在生成之前进行预操作，因此输出不会转到生成日志中，而是转到stdErr.您可以将输出复制到文件:

Pre-action takes place before the build, so output doesn't go to the build log, it goes to stdErr. You can copy the output to a file:

exec > ${PROJECT_DIR}/prebuild.log 2>&1
echo "hello world"

要使环境变量正常工作，还需要将提供构建设置自"设置为适当的目标.

To get the environment variables to work, you also need to set "Provide build settings from" to the appropriate target.

这应该将 hello world 写入项目文件夹中名为"prebuild.log"的文件中.

That should write hello world to a file named "prebuild.log" in your project folder.

如果您希望这些活动结束在构建日志中，请考虑将运行脚本添加到目标的构建阶段.

If you want these activities to end up in the build log, consider adding a run script to your target's build phase instead.
