最近使用cocopods遇到問題
The dependency `` is not used in any concrete target
The dependency `AFNetworking ` is not used in any concrete target
解決方案：
由platform :ios, '10.0.2'?
pod 'pop', '~> 1.0.9'
改成：
platform :ios, '10.0.2'
#use_frameworks!個別需要用到它四濒，比如reactiveCocoa
target 'TestPOP' do
pod "pop", "1.0.9"
end
