Add run script build phase to Xcode project from podspec
提问by opedge
I'm trying to write Cocoapods specification for my library which must modify Xcode project and add "Run Script Build Phase" to project's target. I thought I can use post_installhook. But "pod spec lint" says that this hook is deprecated:
我正在尝试为我的库编写 Cocoapods 规范，该规范必须修改 Xcode 项目并将“运行脚本构建阶段”添加到项目的目标。我以为我可以使用post_install钩子。但是“ pod spec lint”说这个钩子已被弃用：
- WARN | [iOS] The post install hook of the specification DSL has been deprecated, use the `resource_bundles` or the `prepare_command` attributes.
I have no idea how I can replace post_install hook with *resource_bundles* or *prepare_command*. Who knows any other approach to solve my problem? Is it possible?
我不知道如何用 *resource_bundles* 或 *prepare_command* 替换 post_install 钩子。谁知道解决我的问题的任何其他方法？是否可以？
And another problem is how to modify Xcode project to add build phase, but it is actual only when "post_hook problem" is solved.
另一个问题是如何修改Xcode项目添加构建阶段，但只有在“post_hook问题”解决后才实际存在。

Use the Xcodeproj ruby gem (which is part of Cocoapods) to write a script that modifies your Xcode project.
使用 Xcodeproj ruby gem（它是 Cocoapods 的一部分）编写一个脚本来修改您的 Xcode 项目。
You then call this script using the prepare_command.
然后使用prepare_command调用此脚本。
require 'xcodeproj'
path_to_project = "${SOURCE_ROOT}/${PROJECT_NAME}.xcodeproj"
project = Xcodeproj::Project.open(path_to_project)
main_target = project.targets.first
phase = main_target.new_shell_script_build_phase("Name of your Phase")
phase.shell_script = "do sth with ${CONFIGURATION_BUILD_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}/your.file"
project.save()
