有些强迫症不能看到xcode编译报出的警告⚠️，所以在podfile中添加一行
inhibit_all_warnings!
如果没有多个target或者需要所有都隐藏这个黄色警告就在最外层写

# platform :ios, '9.0'
inhibit_all_warnings!

target 'MVVM' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!
   pod 'ReactiveObjC', '~> 3.1.0'
   pod 'MBProgressHUD', '~> 1.1.0'
   pod 'MJRefresh', '~> 3.1.15.7'
  # Pods for MVVM

end

如果有多个target的话就可以在各个需要隐藏的target当中写上这句话

# platform :ios, '9.0'

target 'MVVM' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!
  inhibit_all_warnings!
   pod 'ReactiveObjC', '~> 3.1.0'
   pod 'MBProgressHUD', '~> 1.1.0'
   pod 'MJRefresh', '~> 3.1.15.7'
  # Pods for MVVM

end

target 'RAC' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!
   pod 'Masonry', 
   pod 'AFNetworking',   # Pods for RAC

end
