1，首先是会用的各种block的回调
typedef void (^ _Nullable Success)(id responseObject); // 成功Block
typedef void (^ _Nullable Failure)(NSError *error); // 失败Blcok
typedef void (^ _Nullable Progress)(NSProgress * _Nullable progress); // 上传或者下载进度Block
typedef NSURL * _Nullable (^ _Nullable Destination)(NSURL *targetPath, NSURLResponse *response); //返回URL的Block
typedef void (^ _Nullable DownLoadSuccess)(NSURLResponse * _Nonnull response, NSURL * _Nullable filePath); // 下载成功的Blcok
typedef void (^ _Nullable Unknown)(); // 未知网络状态的Block
typedef void (^ _Nullable Reachable)(); // 无网络的Blcok
typedef void (^ _Nullable ReachableViaWWAN)(); // 蜂窝数据网的Block
typedef void (^ _Nullable ReachableViaWiFi)(); // WiFi网络的Block
2.声明一些常用属性
/**
* 上传图片大小(kb)
*/
@property (nonatomic, assign) NSUInteger picSize;
/**
* 超时时间(默认20秒)
*/
@property (nonatomic, assign) NSTimeInterval timeoutInterval;
/**
* 可接受的响应内容类型
*/
@property (nonatomic, copy) NSSet *acceptableContentTypes;
3.接口请求时用到的方法

* @param reachable 无网络
* @param reachableViaWWAN 蜂窝数据网
* @param reachableViaWiFi WiFi网络
*/

/**
* 封装的POST请求
*
* @param URLString 请求的链接
* @param parameters 请求的参数
* @param success 请求成功回调
* @param failure 请求失败回调
*/
- (void)POST:(NSString *)URLString parameters:(NSDictionary *)parameters success:(Success)success failure:(Failure)failure;
/**

*
* @param URLString 请求的链接
* @param parameters 请求的参数
* @param picArray 存放图片模型(HDPicModle)的数组

*/

*/
- (void)POST:(NSString *)URLString parameters:(NSDictionary *)parameters andPicUrl:(HDPicModle *)picModle progress:(Progress)progress success:(Success)success failure:(Failure)failure;

*/

4.方法的具体实现

*/

{
// 创建网络监测者
