IPHONEOS_DEPLOYMENT_TARGET is se

这里有解决方法这里记录一下。

• 解决方法一(我使用的是这种方法)：

Code Block 
post_install do |installer|
 installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
   config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
  end
 end
end

• 解决方法二：

post_install do |installer|
 installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
   config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
  end
 end
end
