CocoaPods问题总结

例子

 The dependency `` is not used in any concrete target
 The dependency AFNetworking is not used in any concrete target
 

问题原因

 前两天我的OS系统升级了，所以应该执行下面命令！
 sudo gem install cocoapods --pre
 执行完上面命令之后提示！
 Successfully installed cocoapods-1.0.0.beta.2
 Parsing documentation for cocoapods-1.0.0.beta.2
 

 更新了新的版本，然而pod install就出错了，悲了个剧！出错如下：
 Updating local specs repositories
 Analyzing dependencies
 [!] The dependency FMDB (~> 2.3) is not used in any concrete target.
 The dependency SDWebImage (~> 3.6) is not used in any concrete target.
 The dependency AFNetworking (~> 2.3.0) is not used in any concrete target.
 The dependency DACircularProgress (~> 2.2.0) is not used in any concrete target.
 The dependency MBProgressHUD (~> 0.8) is not used in any concrete target.
 The dependency PSTCollectionView (~> 1.2.1) is not used in any concrete target.
 The dependency HPGrowingTextView (~> 1.1) is not used in any concrete target.
 The dependency ProtocolBuffers (= 1.9.3) is not used in any concrete target.
 The dependency leveldb-library (~> 1.18.1) is not used in any concrete target.
 The dependency SCLAlertView-Objective-C (~> 0.7.5) is not used in any concrete target.
 The dependency MWPhotoBrowser (~> 1.4.1) is not used in any concrete target.
 The dependency MMMarkdown (~> 0.5) is not used in any concrete target.
 The dependency MJExtension (~> 2.5.16) is not used in any concrete target.
 The dependency MJRefresh (~> 2.4.12) is not used in any concrete target.
 The dependency Masonry (~> 0.6.3) is not used in any concrete target.
 出这个错是告诉我们我们所用的库没有指定target，它不知道用在哪里，所以就给报错了
 

解决方案

 在创建Podfile的时候，用这种格式使用：
 

 platform :ios, '8.0'
 
 
use_frameworks!个别需要用到它，比如reactiveCocoa
 
 
target 'MyApp' do
 pod 'AFNetworking', '~> 2.6'
 pod 'ORStackView', '~> 3.0'
 pod 'SwiftyJSON', '~> 2.3'
 end
 

 另外一种写法：
 

 platform :ios, '8.0'
 
 
use_frameworks!个别需要用到它，比如reactiveCocoa
 
 
def pods
 pod 'AFNetworking', '~> 2.6'
 pod 'ORStackView', '~> 3.0'
 pod 'SwiftyJSON', '~> 2.3'
 end
 target 'MyApp' do
 pods
 end
