CocoaPods – an Objective-C library manager

Master Build Status Build Status Build Status

CocoaPods manages library dependencies for your Xcode project.

Homepage: http://cocoapods.org/ Twitter: @CocoaPodsOrg Mailing List: http://groups.google.com/group/cocoapods

You specify the dependencies for your project in one easy text file. CocoaPods resolves dependencies between libraries, fetches source code for the dependencies, and creates and maintains an Xcode workspace to build your project.

Ultimately, the goal is to improve discoverability of, and engagement in, third party open-source libraries, by creating a more centralized ecosystem.

See the NSScreencast episode about using CocoaPods for a quick overview on how to get started or create a Pod specification, or the wiki for more in depth information on several topics.

Or, if you’re already using CocoaPods, you can find the changelog here, which contains an overview of the changes in recent versions.

Installation

Downloading and installing CocoaPods only takes a few minutes.

CocoaPods runs on Ruby. To install it run the following commands:

$ [sudo] gem install cocoapods

If you want to have CocoaPods generate documentation for each library, then install the appledoc tool:

$ brew install appledoc --HEAD
$ ln -sf "`brew --prefix`/Cellar/appledoc/HEAD/Templates" ~/Library/Application\ Support/appledoc

Now that you've got CocoaPods installed you can easily add it to your project.

NOTES

  1. If you're using a fresh out of the box Mac with Lion using Xcode from the Mac App Store, you will need to install the Command Line Tools for Xcode first: here
    Or from Xcode > Settings > Downloads > Components > Command Line Tools

  2. CocoaPods re-uses some of the RubyGems classes. If you have a version older than 1.4.0, you will have to update RubyGems: $ gem update --system.

Adding it to your project

Search for Pods by name or description.

$ pod search json

--> JSONKit (1.4, 1.5pre)
    A Very High Performance Objective-C JSON Library.
    - Homepage: https://github.com/johnezang/JSONKit
    - Source:   https://github.com/johnezang/JSONKit.git

--> SBJson (2.2.3, 3.0.4, 3.1)
    This library implements strict JSON parsing and generation in Objective-C.
    - Homepage: http://stig.github.com/json-framework/
    - Source:   https://github.com/stig/json-framework.git

After you've found your favorite dependencies you add them to your Podfile.

$ edit Podfile
platform :ios
pod 'JSONKit',           '~> 1.4'
pod 'Reachability',      '~> 2.0.4'

And then you install the dependencies in your project.

$ pod install

Remember to always open the Xcode workspace instead of the project file when you're building.

$ open App.xcworkspace

Sometimes CocoaPods doesn't have a Pod for one of your dependencies yet. Fortunately creating a Pod is really easy.

$ pod spec create Peanuts
$ edit Peanuts.podspec
$ pod spec lint Peanuts.podspec

Once you've got it running create a ticket and upload the Pod. If you're familiar with Git you can also fork the CocoaPods specs repository and send a pull request. We really love contributions!

There are several other ways to start using any library without a Pod specification, which can be seen in the SSCatalog example.

Collaborate

All CocoaPods development happens on GitHub, there is a repository for CocoaPods and one for the CocoaPods specs. Contributing patches or Pods is really easy and gratifying. You even get push access when one of your specs or patches is accepted.

Follow @CocoaPodsOrg to get up to date information about what's going on in the CocoaPods world.

Donations

  • @fngtps is donating time to work on the design of the forthcoming cocoapods.org website and donated the money to hire Max Steenbergen to design an icon for it.
  • @sauspiel uses CocoaPods for their games and have hired me to add features and specs they needed. These are Nimbus, QuincyKit, and HockeyKit. For the Nimbus spec, the ‘subspecs’ feature was added.
