AFNetworking 在MRC下使用AF第三方网络请求数据 加 -fobjc-arc

**重点内容**    /*  这个是 第三方AFNetworking的下载网址     一 下载： 网址 -- github : https://github.com/AFNetworking/AFNetworking     二 环境：     需要引入的库     CoreLocation.framework           提供定位服务的库文件     SystemConfiguration.framework    提供了一些用于确定设备的网络配置的类库     MobileCoreServices.framework     提供了一些统一的类型标示符     Security.framework               提供数据加密的库文件     AFNetWorking 必须 在arc环境下 如果在MRC 下需要设置-fobjc-arc     如果你的项目使用的是 MRC 模式，则为 ARC 模式的代码文件加入 -fobjc-arc 标签。     如果你的项目使用的是 ARC 模式，则为 MRC 模式的代码文件加入 -fno-objc-arc 标签。
