Dependency- Management Tool! 

Why CocoaPods? • Automate everything! • Save time • Consistant workspace • Really easy updates • Automatic dependency resolution • Solid Xcode configs • Divide project and third party library settings • Docs integrated • Easy to integrate 

Design • Pod = Dependency / Library • Podfile = Description of project dependencies • Podspec = Specification of an Library 

Install CocoaPods [sudo] gem install cocoapods! pod setup 

Demo 

Integrate CocoaPods • Create Podfile Analyzing dependencies Downloading dependencies Installing AFNetworking (2.1.0) Generating Pods project Integrating client project ! [!] From now on use `PodDemo.xcworkspace`. platform :ios, '6.0' ! pod 'AFNetworking', '2.1.0' • Run pod install 

Project.xcodeproj Podfile Project.xcodeproj Pods/AFNetworking Pods/SVProgressHUD Pods/Objection pod install 

Podfile pod 'AFNetworking', '2.1.0' platform :ios, '6.0' inhibit_all_warnings! ! xcodeproj PodDemo.xcodeproj ! pod 'AFNetworking', '2.1.0' pod 'SVProgressHUD', :head ! target :PodDemoTests do pod 'OCMock', '~> 2.2.2' end ! pod 'LocalSourceSpecialPod' :path => 'Libs/LSSP.podspec' pod 'RemoteSourceSpecialPod', :podspec => 'Libs/RSSP.podspec' pod 'RemotePod', :podspec => 'http://goo.gl/HTJ3Ls' 

Semantic versions x: Major version • Major API Changes • Look for incompatibility y: Minor version • Backward compatible • Changes could be needed z: Patch version • Backward compatible • No changes needed x.y.z 

Semantic versions '1.2' Only 1.2 '>1.2' Higher 1.2 '>=1.2' 1.2 or Higher '<1.2' Lower 1.2 '<=1.2' 1.2 or Lower '~>1.2.1' 1.2.1 or Higher AND Lower 1.3 :head Head version from repo 

Podspec Pod::Spec.new do |s| s.name = „AutoScout24 Demo Library" s.version = "1.0" s.summary = "Some description" s.homepage = "https://github.com/AutoScout24/DemoLibrary" s.license = { :type => 'MIT', :file => 'LICENSE' } s.author = { "Felix Schulze" => "[email protected]" } s.source = { :git => "https://github.com/AutoScout24/DemoLibrary.git", :tag => s.version.to_s } ! s.platform = :ios, '5.0' s.requires_arc = true ! s.source_files = 'ASCDemoLibrary*.{h,m}' s.resources = 'ASCDemoLibrary.bundle' ! s.framework = 'Foundation', 'UIKit', 'CoreGraphics', 'QuartzCore' s.weak_frameworks = 'AdSupport‘ ! s.dependency 'AFNetworking', '~> 1.3' ! end
