This is the file extension for CocoaPods, which is distributed as a ruby gem. Which is available in twitter.

EDIT:
编辑：
Cocoapods (http://cocoapods.org/) is a dependency management framework for XCode. It allows you to declaratively define project dependencies and have them included in the build of your project. It's like Apache Maven or Ruby Gems for XCode.
Cocoapods ( http://cocoapods.org/) 是 XCode 的依赖管理框架。它允许您以声明方式定义项目依赖项并将它们包含在您的项目构建中。这就像 XCode 的 Apache Maven 或 Ruby Gems。

As an iOS developer, you certainly use a lot of code made by others, in the shape of libraries. You may not remember, but how complicated would your life be if you had to implement everything from scratch? Usually (since building static libraries manually is sooooo boring), you just add the library code into your project. But that has some disadvantages: Code that could be somewhere else is stored in your repository, wasting space. Sometimes, it's hard to get a specific version of a library. There's no central place where you can see which libraries are available. Finding a new version of a library and updating your project with it is boring and sometimes, painful. Downloading libraries manually creates a tendency to perhaps make some changes to the downloaded code and just leaving it there (making updating harder, as you'll need to merge the changes you made with the code you download for the next version).
作为 iOS 开发人员，您肯定会使用很多其他人编写的代码，以库的形式出现。您可能不记得了，但是如果您必须从头开始实施所有内容，您的生活会有多复杂？通常（因为手动构建静态库太无聊了），您只需将库代码添加到您的项目中。但这有一些缺点：可能在其他地方的代码存储在您的存储库中，浪费空间。有时，很难获得特定版本的库。没有可以查看哪些库可用的中心位置。寻找一个新版本的库并用它更新你的项目很无聊，有时也很痛苦。手动下载库可能会导致对下载的代码进行一些更改并将其留在那里（使更新变得更加困难，因为您
