指定的官方社区我用一个单例类将一些常用的网络请求进行了二次封装，主要包括post请求 get请求 &图片文件上传下载 &视频的断点续传等功能。
首先大家先去github上下载AFN，将文件夹内的AFNetworking文件夹拖入工程中，然后创建一个图片文件参数类代码如下：
#import &Foundation/Foundation.h&
@interface UploadParam : NSObject
上传文件的二进制数据
@property (nonatomic, strong) NSData *
上传的参数名称
@property (nonatomic, copy) NSString *
上传到服务器的文件名称
@property (nonatomic, copy) NSString *fileN
上传文件的类型
@property (nonatomic, copy) NSString *mimeT
#import &UploadParam.h&
@implementation UploadParam
然后创建网络工具AFNManager具体代码如下(此处我提供了代理和block两种方式进行传值供大家选择)：
#import &Foundation/Foundation.h&
#import &AFNManagerDelegate.h&
#import &UploadParam.h&
@interface AFNManager : NSObject
@property (nonatomic, weak) id&AFNManagerDelegate&
AFNManager单利
+(AFNManager *)sharedM
#pragma mark --代理的方式传值
- (void)GET:(NSString *)URLString parameters:(id)
- (void)Post:(NSString *)URLString parameters:(id)
- (void)Upload:(NSString *)URLString parameters:(id)parameters uploadParam:(UploadParam *)uploadP
#pragma mark --block的形式传值

- (void)Upload:(NSString *)URLString parameters:(id)parameters uploadParam:(UploadParam *)uploadParam succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))
#pragma mark --断点续传
@param URLString 请求接口
- (void)downloadStartWithUrl:(NSString *)URLString fileName:(NSString *)fileN
@param URLString 请求接口

可以在此设置进度条

- (void)uploadStartWithUrl:(NSString *)URLString fileData:(NSData *)fileData
operation = [[AFHTTPRequestOperation alloc] initWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:URLString]]];
operation.inputStream = [[NSInputStream alloc] initWithData:fileData];
设置进度条
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
__weak typeof(self) weakself =

[weakself.delegate AFNManagerDidFaild:error];
[operation start];
- (void)operationPause
[operation pause];
- (void)operationResume
[operation resume];
- (void)operationCancel
[operation cancel];
//网络监听（用于检测网络是否可以链接。此方法最好放于AppDelegate中，可以使程序打开便开始检测网络）
- (void)reachabilityManager
AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManager manager];
//打开网络监听
[mgr.reachabilityManager startMonitoring];
//监听网络变化
[mgr.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
switch (status) {
//当网络不可用（无网络或请求延时）
case AFNetworkReachabilityStatusNotReachable:
//当为手机WiFi时
case AFNetworkReachabilityStatusReachableViaWiFi:
//当为手机蜂窝数据网
case AFNetworkReachabilityStatusReachableViaWWAN:
//其它情况
//停止网络监听（若需要一直检测网络状态，可以不停止，使其一直运行）
[mgr.reachabilityManager stopMonitoring];
网络工具代理协议代码如下：
#import &Foundation/Foundation.h&
@class AFNM
@protocol AFNManagerDelegate &NSObject&
发送请求成功
@param manager AFNManager
-(void)AFNManagerDidSuccess:(id)
发送请求失败
@param manager AFNManager
-(void)AFNManagerDidFaild:(NSError *)
