(iOS) Cocoapods

1. Install - Terminal Commands

//To create a new project with CocoaPods, follow these simple steps:

//Create a new project in Xcode as you would normally.
//Open a terminal window, and $ cd into your project directory.
/Create a Podfile. This can be done by running $ pod init.

pod init

//In podfile

//Add supported iOS
platform :ios, '9.0'

//Add target
target 'MyApp' do
  pod 'ObjectiveSugar'
end

//In terminal
pod install

2. Create your own library - Terminal Commands

//Update your system with latest ruby gems by installing ruby gems
sudo gem update --system

//Install CocoaPods in your system
sudo gem install cocoapods
//If the above fails
sudo gem install -n /usr/local/bin cocoapods

//Create a project for CocoaPod
pod lib create AKGitViewControllers

//Updating the pod spec file with your project information

//Lint the podspec file to verify it is valid
pod lib lint

//Push your project to GitHub (or wherever)

//Tag your last commit.
//This step indicates that you are marking this commit as a specific release of your pod.
//The name of the tag should match s.version in your .podspec file.

//Create a Trunk Account (Cocoapod account) if you haven't any
pod trunk register <Your Email>

//Push Your Pod to Cocoapods
pod trunk push <YourProject>.podspec

3. Cocoapods useful commands

//First you can figure out which version of Cocoapods you are on with the command:

sudo gem uninstall cocoapods

//Install the specific version with this command:
sudo gem install cocoapods -v 0.39.0.beta.3

# Be sure to run `pod lib lint ProductFramework.podspec --quick --allow-warnings --sources=afse-specs' to ensure this is a
# valid spec before submitting. Make sure only the following warning appears:
#- WARN  | [iOS] keys: Missing primary key for `source` attribute. The acceptable ones are: `git, hg, http, svn`.
