1.CocoaPods簡介
隨著IOS開發(fā)者的增多,業(yè)界也出現(xiàn)了為IOS程序提供依賴管理的工具,它的名字叫作CocoaPods(http://cocoapods.org/).
GitHub地址:https://github.com/CocoaPods/CocoaPods
2.CocoaPods的安裝
CocoaPods的安裝方式比較簡單,Mac下自帶ruby,使用ruby的gem命令即可下載安裝:
$ sudo gem install cocoapods
$ pod setup
另外,ruby的軟件源rubygems.org因為使用亞馬遜的云服務(wù),所以被屏蔽了,需要更新一下ruby的源,下面的代碼將官方的ruby源替換成國內(nèi)淘寶的源:
gem sources --remove https://rubygems.org/
gem sources -a https://ruby.taobao.org/
gem sources -l
還有一點需要注意,pod setup在執(zhí)行時,會輸出Setting up CocoaPods master repo,但是會等待比較久的時間,這步其實是CocoaPods在將它的信息下載到~/.cocoapods目錄下,如果你等太久,可以試著cd到那個目錄,用du -sh *來查看下載進(jìn)度.
3.使用CocoaPods的鏡像索引
所有項目的Podspec文件都托管在https://github.com/CocoaPods/Specs. 第一次執(zhí)行pod setup時,CocoaPods會將這些Podspec索引文件更新到本地的~/.cocoapods/目錄下,這個索引文件比較大,有80MB左右,所以第一次更新時非常慢.
一個叫akinliu(http://akinliu.github.io/2014/05/03/cocoapods-specs-/) 的朋友在gitcafe(http://gitcafe.com/) 和occhina(http://www.oschina.net/) 上建立了CocoaPods索引庫的鏡像,因為gitcafe和occhina都是國內(nèi)服務(wù)器,所以在執(zhí)行索引更新操作時,會快很多.如下操作可以將CocoaPods設(shè)置成使用gitcafe鏡像:
pod repo remove master
pod repo add master https://gitcafe.com/akuandev/Specs.git
pod repo update
將以上代碼中的https://gitcafe.com/akuandev/Specs.git替換成http://git.oschina.net/akuandev/Specs.git即可使用occhina上的鏡像.
4.使用CocoaPods
使用時需要新建一個名為Podfile的文件,以如下格式,將依賴的庫名字依次列在文件中即可:(示例:JSONKit和AFNetworking)
platform :ios
pod 'JSONKit','~> 1.5pre'
pod 'AFNetworking','~> 2.5.0'
然后將編輯好的Podfile文件放到項目根目錄中,執(zhí)行如下命令即可:
cd "你的項目根目錄"
pod install
現(xiàn)在,所有第三方庫都已經(jīng)下載完成并且設(shè)置好了編譯參數(shù)和依賴,你只需要記住如下兩點即可:
- 使用CocoaPods生成的
*.xcworkspace文件來打開工程,而不是以前的*.xcodeproj文件 - 每次更改了Podfile文件,都需要重新執(zhí)行一次
pod update命令
5.查找第三方庫
如果不知道CocoaPods管理的庫中是否有你想要的庫,那么你可以通過pod search命令進(jìn)行查找,以下是我用pod search AFNetworking查找到的所有可用的庫:
