多target项目适合需要经常打不通环境包的人，方便管理不同环境的项目，具体做法可以查看一个工程多环境切换，适合需要经常打很多不同环境包的人。
多target的时候，如何使用pod呢？正常情况，你的pod是这样的：
# Uncomment the next line to define a global platform for your project # platform :ios, '9.0' source 'https://github.com/CocoaPods/Specs.git' platform :ios, '8.0' inhibit_all_warnings! target 'TestDemo' do # Uncomment the next line if you're using Swift or would like to use dynamic frameworks # use_frameworks! # Pods for TestDemo pod 'UMessage' pod 'MJRefresh' end target 'TestDemoBeta' do # Uncomment the next line if you're using Swift or would like to use dynamic frameworks # use_frameworks! # Pods for TestDemoBeta pod 'UMessage' pod 'MJRefresh' end target 'TestDemoTest' do # Uncomment the next line if you're using Swift or would like to use dynamic frameworks # use_frameworks! # Pods for TestDemoTest pod 'UMessage' pod 'MJRefresh' end target TestDemoPlatform' do # Uncomment the next line if you're using Swift or would like to use dynamic frameworks # use_frameworks! # Pods for TestDemoPlatform pod 'UMessage' pod 'MJRefresh' end
如果使用的第三方比较少，你且可以这么写，但是如果比较多怎么办？这里博主给出一个优雅的写法：
# Uncomment the next line to define a global platform for your project # platform :ios, '9.0' source 'https://github.com/CocoaPods/Specs.git' platform :ios, '8.0' inhibit_all_warnings! def testDemo_pods pod 'UMessage' pod 'MJRefresh' end target 'TestDemo' do # Uncomment the next line if you're using Swift or would like to use dynamic frameworks # use_frameworks! # Pods for TestDemo testDemo_pods end target 'TestDemoBeta' do # Uncomment the next line if you're using Swift or would like to use dynamic frameworks # use_frameworks! # Pods for TestDemoBeta testDemo_pods end target 'TestDemoTest' do # Uncomment the next line if you're using Swift or would like to use dynamic frameworks # use_frameworks! # Pods for TestDemoTest testDemo_pods end target TestDemoPlatform' do # Uncomment the next line if you're using Swift or would like to use dynamic frameworks # use_frameworks! # Pods for TestDemoPlatform testDemo_pods end
也就是只需要增加一个定义：
//这里注意，testDemo_pods这个定义的名字一定不能大写字母开头，否则pod install不执行，小写即可 def testDemo_pods end
你学会了么？喜欢就点个赞吧。
