Example project

1. Install Xcode or command line tools (xcode-select --install)
2. sudo gem install cocoapods (if needed: sudo gem update --system)
3. Create new Xcode project
4. touch Podfile && open -e Podfile
5. pod install

Sample Podfile

platform :ios, '7.0'

pod 'AFNetworking'

Resulting directory layout:

- Project/
	- Project/
		- *.{h,m}
	- Project.xcodeproj
	- Project.xcworkspace
	- Podfile
	- Pods/
		- Pods.xcodeproj 

Discussion:

• Xcode workspace, projects, Build Phases, Info settings
• Podfile.lock, Pods directory
• Check in Pods directory
• pod outdated, pod update

Tips & tricks

• Alternative directory layout using xcodeproj
• Version selector: <, >, =, ~>, e.g. AFNetworking ~> 1.3
• Head: pod 'AFNetworking', :head
• Fork or specific version: pod 'AFNetworking', :git => 'https://github.com/gowalla/AFNetworking.git', :commit => '082f8319af'
• git submodules vs Cocoapods
  • pod 'AFNetworking', :path => '~/Documents/AFNetworking'
• Binary pods
• Version numbers: 3.0.3a
• Test target only pod -> https://github.com/optionu/stolpersteine-ios/blob/master/Podfile
• Reveal -> no configuration based pod
• Version Eye
• Private pods: http://guides.cocoapods.org/making/private-cocoapods.html

Create your own pod

1. pod spec create AlertViewController or copy from existing podspec
2. open -e AlertViewController.podspec
3. Add pod 'AlertViewController', :path => '..' to your project for testing
4. When done testing, tag source code with version
5. pod spec lint
6. Fork Specs repo
7. Add your podspec and create pull request

Sample podspec

Pod::Spec.new do |s|
  s.name     = 'AlertViewController'
  s.version  = '0.0.1'
  s.license  = 'MIT'
  s.summary  = 'Cocoapods workshop excercise.'
  s.homepage = 'https://github.com/choefele/cocapods-workshop'
  s.authors  = { 'Claus Höfele' => '[email protected]' }
  s.social_media_url = 'https://twitter.com/claushoefele'
  s.source   = { :git => 'https://github.com/choefele/cocapods-workshop.git', :tag => s.version.to_s }
  s.requires_arc = true

  s.ios.deployment_target = '6.0'

  s.source_files = 'Pod/*.{h,m}'
end
