Create Xcode Project with Ruby XcodeProj
提问by btype
I had this idea of making a command line utility similar to the rails setup application. It should automatically create a Xcode project, setup unit test, setup Frank, install most used Cocoapods and setup a project structure.
我有制作一个类似于 rails setup 应用程序的命令行实用程序的想法。它应该自动创建一个 Xcode 项目，设置单元测试，设置 Frank，安装最常用的 Cocoapods 并设置项目结构。
There is no such thing at the moment and I would really like to have it and open source it. I struggled around the other questions here yesterday but found nothing up to date.
目前没有这样的东西，我真的很想拥有它并开源它。昨天我在这里挣扎了其他问题，但没有发现任何最新信息。
I came up with the idea using XcodeProjwhich is used by CocoaPods to generate a project containing the Pods. So it should not be impossible to do. I also found XcodeProjectbut this seems to be read-only.
我想出了使用XcodeProj的想法，CocoaPods使用它来生成包含 Pod 的项目。所以这应该不是不可能做到的。我还找到了XcodeProject但这似乎是只读的。
Can someone (maybe of the Cocoapods developers) give me a hint where to start, because the Xcodeproj gem is very undocumented.
有人（可能是 Cocoapods 开发人员）能给我一个从哪里开始的提示，因为 Xcodeproj gem 非常没有记录。

To the best place to start to use Xcodeproj is the Xcodeproj::Projectclass.
开始使用 Xcodeproj 的最佳位置是Xcodeproj::Project类。
Once you open a project the Xcodeproj API allows to edit all the known attributes easily. However you need to keep in mind the following concepts:
打开项目后，Xcodeproj API 允许轻松编辑所有已知属性。但是，您需要记住以下概念：
- If an attribute is a String you can edit it directly.
- If an attribute stores an object it is necessary to ask the project to create a newone so it is has the chance to assign an UUID.
- If you are editing an attribute which stores a list of objects it is safe only to use the method exposed by the ObjectList.
- Xcodeproj performs type checking when you assign values to attributes.
- 如果属性是字符串，您可以直接编辑它。
- 如果一个属性存储一个对象，则有必要要求项目创建一个新对象，以便它有机会分配一个 UUID。
- 如果您正在编辑存储对象列表的属性，则仅使用ObjectList公开的方法是安全的。
- 当您为属性赋值时，Xcodeproj 会执行类型检查。
The following lightly tested code should help to get you started by creating a new project named Test with a target named App for a deployment target of iOS 6.0 that adds Class.h and Class.m file to the project, ensuring Class.m is included in the target.
以下经过简单测试的代码应该有助于帮助您开始创建一个名为 Test 的新项目，目标名为 App，用于 iOS 6.0 的部署目标，将 Class.h 和 Class.m 文件添加到项目中，确保包含 Class.m在目标中。
require 'xcodeproj'
proj = Xcodeproj::Project.new
app_target = proj.new_target(:application, 'App', :ios, '6.0')
header_ref = proj.main_group.new_file('./Class.h')
implm_ref = proj.main_group.new_file('./Class.m')
app_target.add_file_references([implm_ref])
proj.save_as('Test.xcodeproj')
