AFNetworking是一個輕量級的iOS網(wǎng)絡(luò)通信類庫固以。它建立在NSURLConnection和NSOperation等類庫的基礎(chǔ)上掐松，讓很多網(wǎng)絡(luò)通信功能的實現(xiàn)變得十分簡單齐鲤。

AFNetworking框架的 Github地址

• 使用AFNetwork來檢測網(wǎng)絡(luò)狀態(tài)

-(void)reach
{
   /*
       AFNetworkReachabilityStatusUnknown          = -1,   未知
       AFNetworkReachabilityStatusNotReachable     = 0,    未連接
       AFNetworkReachabilityStatusReachableViaWWAN = 1,    3G 花錢
       AFNetworkReachabilityStatusReachableViaWiFi = 2,    WIFI
    */
   //如果要檢測網(wǎng)絡(luò)狀態(tài)的變化瓦糟，必須用檢測管理器的單例
   [[AFNetworkReachabilityManager sharedManager] startMonitoring];
   
   [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
       NSLog(@"status = %ld",status);
   }];
}

• 使用AFNetwork 的 GET方法 獲取信息

-(void)getRequestWithUrl:(NSString *)urlString WithParameters:(NSDictionary *)dictionary
{
    NSURL *url = [NSURL URLWithString:urlString];
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [manager GET:url.absoluteString parameters:dictionary progress:^(NSProgress * _Nonnull downloadProgress) {
        NSLog(@"下載 = %@",downloadProgress);
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

     //通知
    [[NSNotificationCenter defaultCenter] postNotificationName:@"center" object:nil userInfo:responseObject];
    
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"錯誤 = %@",error);
    }];
   
}

• 使用AFNetwork 的 POST 上傳純文本信息

-(void)postWeiboWithUrl:(NSString *)urlString WithParameters:(NSDictionary *)dictionary
{
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    //返回格式
    //這里得到的是 JSon 數(shù)據(jù)堵泽，默認(rèn)的 responseSeroalizer 也是 JSon 數(shù)據(jù)
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    //得到的是 NSData 數(shù)據(jù)
//    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    //接受一些類型
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", nil];
    
    NSURL *url = [NSURL URLWithString:urlString];
    [manager POST:url.absoluteString parameters:dictionary progress:^(NSProgress * _Nonnull uploadProgress) {
        NSLog(@"上傳 = %@",uploadProgress);
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSLog(@"響應(yīng) = %@",responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"錯誤 = %@",error);
    }];
}

• 使用AFNetwork 的 POST 方法 上傳文本和圖片

-(void)postWeiboWithUrl:(NSString *)urlString WithParameters:(NSDictionary *)dictionary WithImageName:(NSString *)imageName
{
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", nil];
    
    NSURL *url = [NSURL URLWithString:urlString];
    [manager POST:url.absoluteString parameters:dictionary constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
        
        NSData *data = UIImagePNGRepresentation([UIImage imageNamed:@"voiceChange"]);
//      NSData *data1 = UIImageJPEGRepresentation([UIImage imageNamed:@"voiceChange"], 0.5);
        
        [formData appendPartWithFileData:data name:@"pic" fileName:@"測試.png" mimeType:@"png"];
        
    } progress:^(NSProgress * _Nonnull uploadProgress) {
        NSLog(@"上傳 = %@",uploadProgress);
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSLog(@"響應(yīng) = %@",responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"錯誤 = %@",error);
    }];
}
