iOS上传语音、文字、图片

需求：用户可能提交 文字，也可能有语音，还有可能有图片。当然 都有也是可以的。
在这里我的方案是 先做判断（因为我提交的类不同（也就是方法不一样））；

    （1）if (_imageArray.count == 0 && recordingInterval == 0){
  //只有文字
}else{

    // 文字 图片 加录音
}

方法：

// 有文字,有图,片有语音
+(void)askTextImageByUserInfoId:(NSString *)userInfoId
                WithUserRelationId:(NSString *)userRelationId
                 WithAskContent:(NSString *)askContent
             WithImageDataArray:(NSMutableArray *)imageDataArray
                  WithVoiceData:(NSData *)voiceData
                        success:(void (^)(id askDescArray))success
                        failure:(void (^)(NSError *error))failure`

具体实现：

/**
 *  请求Opinion Server Api 接口方法
 *
 *  @param request 自定义的Request请求
 *  @param userInfoId 对应人的唯一标示（用户本人  和  关系人）
 *  @param token token值
 *  @param imageAndVoiceDataArray  盛放图片 语音的数组
 *  @param success 请求成功,返回Response对象
 *  @param failure 请求失败
 *  @param cached  是否进行缓存
 */
+ (void)requestWithPOST:(NetWorkBaseRequest *)request WithImageDataArray:(NSMutableArray *)imageDataArray WithVoiceData:(NSData *)voiceData success:(void (^)(NetWorkBaseResponse *responseObject))success
                failure:(void (^)(NSError *error))failure
                  cache:(BOOL)cached
{


    if (!request) {
        NSLog(@"[ERROR] request cannot be NULL");
        if (failure) {

            failure([NSError errorWithDomain:@"" code:-1 userInfo:nil]);
        }
        return;
    }

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    [manager.requestSerializer setValue:@"multipart/form-data;charset=utf-8"forHTTPHeaderField:@"Content-Type"];

    manager.requestSerializer.timeoutInterval = 10;
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [manager.requestSerializer setCachePolicy:NSURLRequestReturnCacheDataElseLoad];

    NSString *tokenValue = [SSKeychain passwordForService:[AppUtils appServiceName] account:[AppUtils tokenKey]];
    if (!tokenValue) {

        tokenValue = @"";
    }else{

        [request.paramDic setValue:tokenValue forKey:@"token"];
    }

    [manager POST:request.stringOfApiURLString parameters:request.paramDic constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
        //对传进来的 图片  数组进行遍历
        for (int i = 0; i < imageDataArray.count; i++) {

            NSData *imgData = imageDataArray[i];

            //用这个当图片的名字，一起到图片名不重复的效果
            NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
            NSString *tupianming = [NSString stringWithFormat:@"yyyyMMddHHmmssSSSS%d",i];

        }
        if(voiceData!=nil){

            luyinname = [NSString stringWithFormat:@"/%@.amr",[dateFormatter stringFromDate:[NSDate date]]];
            //让服务器识别这个音频的格式 为  amr
