cocos2d-x-3.14.1 の static ライブラリを CocoaPod にする

環境

1. Mac OS X 10.12.4 (英語)
2. Xcode 8.3.1
3. CocoaPods 1.2.0

CocoaPod 作成手順

1. ヘッダーファイルとライブラリを cocos2d-x からコピー

   $ mkdir pod-cocos2d-x-kenichi-3.14.1.0
   $ cd pod-cocos2d-x-kenichi-3.14.1.0
   $ mkdir Headers
   $ (cd ../cocos2d-x-3.14.1/cocos; tar cf - `find . -name '*.h' -not -path '*/android/*'`) | (cd Headers; tar xzf -)
   $ (cd ../cocos2d-x-3.14.1/cocos; tar cf - `find . -name '*.inl'`) | (cd Headers; tar xzf -)
   
   $ mkdir Libraries
   $ cp -p "../cocos2d-x-3.14.1/build/libcocos2d iOS.a" Libraries/libcocos2d-iOS.a
   

   1. kenichi は適当に置き換える事
   2. cocos2d-x の static ライブラリをビルドしたライブラリを使った
   3. CocoaPods-1.0.0: ライブラリファイル名がスペースを含むと間違った xcconfig ファイルを生成してしまうので - に置換した

2. tar してアップロード

   $ cd ..
   $ tar cjf pod-cocos2d-x-kenichi-3.14.1.0.tar.bz2 pod-cocos2d-x-kenichi-3.14.1.0
   

3. pod-cocos2d-x-kenichi-3.14.1.0.podspec を作成してアップロード

   Pod::Spec.new do |s|
     s.name         = "cocos2d-x-kenichi"
     s.version      = "3.14.1.0"
     s.summary      = "cocos2d-x prebuild libraries for arm64, armv7, x86_64, i386"
     s.author       = "Kenichi"
     s.license      = "MIT"
     s.homepage     = "https://10.10.10.10/dev/cocoapods/"
     s.platform     = :ios, "8.0"
     s.source       = { :http => "https://10.10.10.10/dev/cocoapods/pod-cocos2d-x-kenichi-3.14.1.0.tar.bz2", :type => :tbz }
     s.preserve_paths = "Headers/**/*.{h,inl}"
     s.public_header_files = "Headers/**/*.{h,inl}"
     s.header_mappings_dir = "Headers"
     s.vendored_libraries = 'Libraries/libcocos2d-iOS.a' # CocoaPods-1.0.0 messes up OTHER_LDFLAGS in xcconfig if the path contains a space
     s.frameworks = [ "AudioToolbox", "CoreMotion", "AVFoundation", "GameController", "MediaPlayer", "OpenAL" ] # AVFoundation, GameController, MediaPlayer, OpenAL are needed because CocoaPods adds -ObjC flag
     s.libraries = [ "z", "iconv" ]
     s.xcconfig = { 'GCC_PREPROCESSOR_DEFINITIONS' => 'USE_FILE32API CC_ENABLE_CHIPMUNK_INTEGRATION=1' } # TODO: COCOS2D_DEBUG=1 should also be added for Debug configuration
   end
   

   1. 10.10.10.10 は適当に置き換える事
   2. CocoaPods-1.0.0: source の :type を指定しないと Unsupported file type エラー

CocoaPod 利用手順

1. Podfile を作成

   platform :ios, '8.0'
   use_frameworks!
   
   target 'HelloCpp-mobile' do
     pod 'cocos2d-x-kenichi', :podspec => 'http://10.10.10.10/dev/cocoapods/pod-cocos2d-x-kenichi-3.14.1.0.podspec'
   end
   

2. Pod をインストール

   $ pod install
   Analyzing dependencies
   Fetching podspec for `cocos2d-x-kenichi` from `https://10.10.10.10/dev/cocoapods/pod-cocos2d-x-kenichi-3.14.1.0.podspec`
   Downloading dependencies
   Installing cocos2d-x-kenichi (3.14.1.0)
   Generating Pods project
   Integrating client project
   
   [!] Please close any current Xcode sessions and use `HelloCpp.xcworkspace` for this project from now on.
   Sending stats
   Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.
   

3. おまけ: CocoaPods-1.0.0 で Podfile に以下を追加して Debug 時に COCOS2D_DEBUG=1 を定義したかったが、効かなかった

   post_install do |installer|
     installer.pods_project.targets.each do |target|
       target.build_configurations.each do |config|
         config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] = ['COCOS2D_DEBUG=1']
       end
     end
   end
