关于AFNetworking 3.0
NSURLConnection的API已废弃
AFNetworking 1.0 是建立在 NSURLConnection基础上的，AFNetworking 2.0 开始使用基于 NSURLConnection API基础功能，同时也有基于新的NSURLSession API 的功能实现。AFNetworking 3.0现在是专门建立在 NSURLSession 顶层的，这降低了维护负担，同时允许支持苹果为 NSURLSession 提供的任何额外的增强的特性。在Xcode 7，NSURLConnection API 已经被苹果官方弃用。然而API函数将继续使用不会受影响，只不过再也不会添加新的功能了，苹果建议所有基于网络的功能在未来都能使用 NSURLSession。
3.0 被移除的类有
• AFURLConnectionOperation
• AFHTTPRequestOperation
• AFHTTPRequestOperationManager
转而替代的是
• AFURLSessionManager
• AFHTTPSessionManager
下面的方法也是基于NSURLSession进行封装的
所有的请求方法都在NetWorkManager.m进行统一设置，并且全部为类方法(调用方便)
tips
1.设置网路请求的
BaseURL,请移步Supporting Files-->const.h中进行修改
#define BaseURL @"http://apis.baidu.com/apistore"
//请正确设置baseUrl的格式 否则会报无效的url(可参考demo中的设置)
2.关于tokken的设置
#warning 此处做为测试 可根据自己应用设置相应的值
/**设置apikey ------类似于自己应用中的tokken---此处仅仅作为测试使用*/
[self.requestSerializer setValue:apikey forHTTPHeaderField:@"apikey"];
主要实现的功能
1.文件下载
2.多图压缩上传
3.视频上传（文件上传,音频上传类似）
4.取消所有的网络请求
5.取消指定的网络请求
暂未考虑缓存请求到的数据
