这是我的pod文件:

source 'https://github.com/CocoaPods/Specs.git'
pod 'AFNetworking', '~> 2.5'
use_frameworks!

您需要确保安装了CocoaPod(0.36)的测试版.唯一的问题是，您将能够在iOS 7上运行它，但是 它不会通过苹果应用程序提交时的验证 (请记住这一点.)

You need to make sure you install the beta version of CocoaPod (0.36). The only issue with this is that you will be able to run it on iOS 7 but it will not pass the validation on apple application submission (keep that in mind).
