Answer 1

尝试使用Afnetworking 3.0

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"your server url" parameters:@{@"parameter_1":@"string 1",@"parameter_2":@"string 2"} constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
            if (image) {
                [formData appendPartWithFileData:UIImageJPEGRepresentation(image, 0.8) name:imagename fileName:@"recipeImage.jpg" mimeType:@"image/jpeg"];
            }

        }error:nil];

        AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
        manager.responseSerializer = [AFJSONResponseSerializer serializer];

        NSURLSessionUploadTask *uploadTask;
        uploadTask = [manager
                      uploadTaskWithStreamedRequest:request
                      progress:^(NSProgress * _Nonnull uploadProgress) {
                          dispatch_async(dispatch_get_main_queue(), ^{
                          });
                      }
                      completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
                          if (error) {
                              NSLog(@"Error: %@", [[NSString alloc]initWithData:[[error valueForKey:@"userInfo"] valueForKey:@"com.alamofire.serialization.response.error.data"] encoding:NSUTF8StringEncoding]);

                          } else {
                              NSLog(@"%@",responseObject);// your response here
                              callback(YES,responseObject);
                          }
                      }];

        [uploadTask resume];

Answer 2

NSData *dataImage = UIImagePNGRepresentation(yourImage);

NSString *imageBase64 = [dataImage base64forData];

- (NSString*)base64forData
{
    const uint8_t* input = (const uint8_t*)[self bytes];
    NSInteger Datalength = [self length];

    static char table[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";

    NSMutableData* data = [NSMutableData dataWithLength:((Datalength + 2) / 3) * 4];
    uint8_t* output = (uint8_t*)data.mutableBytes;

    NSInteger i;
    for (i=0; i < Datalength; i += 3) {
        NSInteger value = 0;
        NSInteger j;
        for (j = i; j < (i + 3); j++) {
            value <<= 8;

            if (j < Datalength) {
                value |= (0xFF & input[j]);
            }
        }

        NSInteger theIndex = (i / 3) * 4;
        output[theIndex + 0] =                    table[(value >> 18) & 0x3F];
        output[theIndex + 1] =                    table[(value >> 12) & 0x3F];
        output[theIndex + 2] = (i + 1) < Datalength ? table[(value >> 6)  & 0x3F] : '=';
        output[theIndex + 3] = (i + 2) < Datalength ? table[(value >> 0)  & 0x3F] : '=';
    }

    return [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];


}
