pod安装AFNetworking3.0遇到dependency were found, but they required a higher minimum deployment target

根据github上的步骤安装

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'

pod 'AFNetworking', '~> 3.0'

遇到了以下提示

[!] Unable to satisfy the following requirements:

- `AFNetworking (~> 3.0)` required by `Podfile`

Specs satisfying the `AFNetworking (~> 3.0)` dependency were found, but they required a higher minimum deployment target.

在网上寻找了不少解决方案，都无效，

后来按照下列方法成功安装

CocoaPods 0.39.0+
is required to build AFNetworking 3.0.0+.安装升级cocoapod

然后

platform :ios, '8.0'
pod 'AFNetworking', '~> 3.0'

put those lines into the end and it will work;（stackoverflow）
就解决问题了，呵呵哒
