我已经做了几个月的iOS开发了,刚刚了解到有前途的用于依赖管理的CocoaPods库。
我在一个个人项目中尝试过:在我的Podfile中添加了对Kiwi的依赖,运行pod install CocoaPodsTest。Xcodeproj,瞧,它工作得很好。
我唯一想知道的是:我要签入什么,为了版本控制我要忽略什么?似乎很明显,我想签入Podfile本身,也可能是.xcworkspace文件;但是我是否忽略了Pods/目录?是否还会生成其他文件(当我添加其他依赖项时),也应该添加到.gitignore中?
是否检入Pods文件夹取决于您,因为工作流程因项目而异。我们建议您将Pods目录置于源代码控制之下,不要将其添加到.gitignore中。但最终这个决定取决于你:
签入Pods目录的好处
克隆repo之后,项目可以立即构建和运行,甚至不需要在机器上安装CocoaPods。不需要运行pod install,也不需要连接互联网。
Pod构件(代码/库)总是可用的,即使Pod的源(例如GitHub)宕机。
克隆repo后,Pod工件保证与原始安装中的工件相同。
忽略Pods目录的好处
The source control repo will be smaller and take up less space.
As long as the sources (e.g. GitHub) for all Pods are available, CocoaPods is generally able to recreate the same installation.(Technically there is no guarantee that running pod install will fetch and recreate identical artifacts when not using a commit SHA in the Podfile. This is especially true when using zip files in the Podfile.)
There won't be any conflicts to deal with when performing source control operations, such as merging branches with different Pod versions.
Whether or not you check in the Pods directory, the Podfile and Podfile.lock should always be kept under version control.
最后取决于你采取的方法。
Cocoapods团队是这么想的:

pod目录下的源代码控制,不要将它添加到您的
.gitignore。但最终这个决定取决于你。
就我个人而言,我想把Pods排除在外,如果我使用Node,就像node_modules,如果我使用Bower,就像bower_components。这适用于几乎所有的依赖管理器,也是git子模块背后的理念。
然而,有时你可能想要真正确定某个依赖项的最新状态,这样你才能在项目中拥有该依赖项。当然,如果您这样做,会有一些缺点,但这些问题不仅适用于Cocoapods,而且适用于任何依赖管理器。
下面是Cocoapods团队制作的利弊清单,以及之前提到的引文全文。
Cocoapods团队:我应该将Pods目录检入源代码控制吗?
Cocoapod文档中直接给出了答案。你可以看看“http://guides.cocoapods.org/using/using-cocoapods.html#should-i-ignore-the-pods-directory-in-source-control”。
Whether or not you check in your Pods folder is up to you, as
workflows vary from project to project. We recommend that you keep the
Pods directory under source control, and don't add it to your
.gitignore. But ultimately this decision is up to you:
Benefits of checking in the Pods directory
After cloning the repo, the project can immediately build and run, even without having CocoaPods installed on the machine. There is no
need to run pod install, and no Internet connection is necessary.
The Pod artifacts (code/libraries) are always available, even if the source of a Pod (e.g. GitHub) were to go down.
The Pod artifacts are guaranteed to be identical to those in the original installation after cloning the repo.

我提交我的Pods目录。我不同意Pods目录是一个构建产物。事实上,我想说它绝对不是。它是应用程序源代码的一部分:没有它就无法构建!
我们更容易将CocoaPods视为开发工具,而不是构建工具。它不构建你的项目,它只是为你克隆和安装你的依赖项。为了能够简单地构建项目,不应该必须安装CocoaPods。
通过使CocoaPods成为构建的依赖项,您现在需要确保它在构建项目所需的任何地方都可用……团队管理员需要它,您的CI服务器需要它。通常,您应该始终能够克隆源存储库并进行构建,而不需要做任何进一步的工作。
如果你频繁切换分支,不提交pod目录也会造成巨大的麻烦。现在,每次切换分支时都需要运行pod install,以确保依赖项是正确的。当你的依赖关系稳定时,这可能不那么麻烦,但在项目早期,这是一个巨大的时间消耗。
我忽略了什么?什么都没有。Podfile,锁文件和Pods目录都被提交。相信我,这会帮你省去很多麻烦。缺点是什么?更大一点的回购?又不是世界末日。
我必须说,我是将pod提交到存储库的粉丝。按照前面提到的链接,你会得到一个很好的。gitignore文件来启动你的iOS Xcode项目,以允许Pods,但如果你愿意,你也可以轻松地排除它们:https://github.com/github/gitignore/blob/master/Objective-C.gitignore
我之所以热衷于将pod添加到存储库中,有一个根本原因,但似乎没有人注意到,如果我们的项目如此依赖的库突然从网络上删除了,会发生什么?
Maybe the host decides they no longer want to keep their GitHub
account open What happens if the library is say several years old
(like older than 5 years for example) there is a high risk the
project may no longer be available at source
Also another point, what happens if the URL to the repository
changes? Lets say the person serving the Pod from their GitHub
account, decides to represent themselves under a different handle -
your Pods URLs are going to break.
Finally another point. Say if you're a developer like me who does a lot
of coding when on a flight between countries. I do a quick pull on
the 'master' branch, do a pod install on that branch, while sitting
in the airport and have myself all set for the upcoming 8 hour
flight. I get 3 hours into my flight, and realise I need to switch to
another branch.... 'DOH' - missing Pod information which is only available on the 'master' branch.
NB……请注意,用于开发的“主”分支只是举个例子,很明显,版本控制系统中的“主”分支应该保持干净,并且在任何时候都可以部署/构建
我认为从这些方面来看,在代码存储库中创建快照肯定比严格限制存储库大小要好。如前所述,播客文件。锁文件-而版本控制将给你一个良好的Pod版本历史。
在一天结束的时候,如果你有一个紧迫的截止日期,预算紧张,时间是至关重要的——我们需要尽可能多的资源,不要把时间浪费在严格的意识形态上,而是利用一套工具一起工作——让我们的生活更容易、更有效。
