How to install CocoaPods and setup with your Xcode project

Sometimes we are using many Git libraries inside our app. Like JSONKit, AFNetworking,  MBProgressHUD, EGOTableViewPullRefresh, Facebook-iOS-SDK etc. But it is very boring to build all libraries or if you add the code in your project, it is tough to manage. Also, there are many disadvantages in this:

  • 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 time taking and sometimes, painful.
  • Downloading libraries manually creates a tendency to perhaps make some changes to the downloaded code.
  • Updating is harder.

The most simplest solution is to use CocoaPods.

CocoaPods is the dependency manager for Objective-C projects. It has thousands of libraries and can help you scale your projects elegantly. CocoaPods is built with Ruby and is installable with the default Ruby available on OS X.

Installation:

Before installing Pods make sure you have installed/updated command line tool in your Mac machine. You can check this by opening Xcode, navigating the menu to Xcode > Preferences > Downloads > Components, finding Command Line Tools and select install/update.

command-line-tools

Also, make sure Git is installed in your Mac machine.

Open terminal and run this command:

sudo gem install cocoapods

Enter admin password. This could take a while. After few minutes it will show green message is cocoa pods installed successfully in your mac machine.

If you are getting any error with XCode like developer path is missing. First run this command in terminal: sudo xcode-select -switch /Applications/Xcode.app (or your XCodeName.app)

Hurrah….You successfully installed CocoaPods in your mac machine. Now you can setup Pod with your Xcode project.

How to setup POD for your Xcode project:

1. Open Terminal

2. Change directory to your XCode project root directory (where your ProjectName.xcodeproj file is placed).

3. $ pod setup : (Setting up CocoaPods master repo)

If successful, it shows : Setup completed (read-only access). So, you setup everything. Now Lets do something which is more visible…Yes ! Lets install libraries in your Xcode project.

Steps to add-remove-update libraries in pod:

1. Open Terminal

2. Change directory to your XCode project root directory. If your terminal is already running then no need to do this, as you are already at same path.

3. $ touch podfile

4. $ open -e podfile (This should open a blank text file or you can use: open -a Xcode podfile to open this inside Xcode)

5. Add your library names in that text file. You can add new names (lib name), remove any name or change the version. If you are using CocoaPods 1.0 or above you also have to have a ‘target’ section in your Pod File.

target '<Your Target Name>' 
do 
 pod 'AFNetworking', '~> 3.0' 
 pod 'FBSDKCoreKit'
 pod 'JSONKit'
 pod 'MBProgressHUD'
end

NOTE: Use ( control + ” ) button to add single quote at both end of library name. It should be shown as straight vertical line. Without control button it shall be added as curly single quote which will give error while installation of file.

6. Save and close this text file. Now libraries are setup and you have to install/update it.

7. Go to your terminal again and run this command: $ pod install (to install/update these libraries in pod).

You should see output similar to the following:

Updating spec repo `master’
Installing AFNetworking (3.0)…
Generating support files
After successful downloading/installation of any single library, It will generate ProjectName.xcworkspace in your project root directory. From now use this workspace to open your project. When you open your project work space you will see Pod is also added as another Xcode project with your Xcode project. If you open Pod it will show all libraries.

For your next project your don’t need to install the cocoa pod again in your mac machine just open the terminal and setup the Pod in root directory of your Xcode project and always remember these 3 commands :

  • 1. $ touch podfile
  • 2. $ open -e podfile
  • 3. $ pod install

To update Pod libraries : $ pod update

To check POD version : $ pod –version
To update CocoaPods : $ gem install cocoapods or use sudo at start if getting error “You don’t have write permissions for the /Library/Ruby/Gems/2.0.0 directory.”

  1. I followed the steps also it was successfully installed….. but after that too when i imported RestKit in AppDelegate.h it is giving me error as RestKit file not found…. Please can you give me any suggestion how to get rid of this error?

        • Are you able to see POD xcode project in your original project ? Is this showing all libraries which is added in your POD ?

          • yes… Sir I can see the pod file also the files included in it.. but still I have been facing the problem of RestKit not found

          • Hey Disha, I am still not sure why you getting such issue with RestKit. Only thing i can advise to reinstall POD libraries (specially for Rest Kit). Also, are you using any specific version for POD libraries ? like : platform :ios, ‘5.0’ ? Make sure, Your RestKit lib is supporting your XCode platform version.

      • Thank you.
        AppDelegate is pre added file when you create a new project. It will not show inside cocoaPods, will only display inside your original xcode project.

          • You can just use #import “AFNetworking.h” anywhere where you want to import. If you are unable to do this, make sure your pod is installed correctly and also you installed AFNetworking in your pod.

          • i can see Pods Folder with 3 targets

            when i try to import #import “Af”

            i can’t get the file besides i am getting AppDelegate file only in ViewController.h file
