在php：

Upload方法：

    /**
     * ### this function is file upload
     * auto file name  and file path
     * @param $FILES  File to file
     * @param string $A
     * @param string $B
     * @return bool|string
     */
    protected function Upload($FILES,$A="",$B=""){
        $ReturnFILE = array();
        $FILES = array_keys($FILES);
        foreach ($FILES as $K => $V) {
            $FlodName = "Updata/".date("Y-m-d");
            if(!is_dir($FlodName)){
                mkdir($FlodName,777,true);
            }
            if ($_FILES[$FILES[$K]]["error"] > 0){
                return false;
            }
            $tempEXT = strstr($_FILES[$FILES[$K]]["name"],".");
            $FileName = date("YmdHis").UUID().$tempEXT;
            move_uploaded_file($_FILES[$FILES[$K]]["tmp_name"],"{$FlodName}/" . $FileName);
            $http_type = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') || (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')) ? 'https://' : 'http://';
            $FileName =$http_type.$_SERVER['HTTP_HOST']."/".$FlodName."/".$FileName;
            $ReturnFILE[] = $FileName;
        }
        return $ReturnFILE;
    }

ImageEdit方法使用Upload方法上传iOS应用旁路图片：

 public function ImgEdit()
 {

    $imgs=$this->Upload($_FILES);
    var_dump($imgs); 
    // success 
    if (!empty($imgs)){
        echo 1;
        $datas = [
            'code' => 200,
            'message' => "修改成功",
            'data' =>$imgs
        ];
        echo json_encode($datas);
    } else {  // fail
        echo 2;
        $datas = [
            'code' => 0,
            'message' => "修改失败",
            'data' => ""
        ];
        echo json_encode($datas);
    }
}

在iOS应用中，我使用此方法上传我的图片：

- (void)networkUploadHeadImage:(UIImage *)image {

    UIImage *img = image;
    NSData *dataObj = UIImagePNGRepresentation(img);

    NSDictionary * param1 = @{
                              @"imgFile":dataObj
                              };
    AFHTTPSessionManager * session = [AFHTTPSessionManager manager];
    session.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",@"application/xml",@"text/json",@"text/javascript",@"text/html",@"text/plain",@"multipart/form-data",nil];

    //拼接地址
    NSString *url = @"http://103.71.178.145:8088/Home/Aboutus/ImgEdit";

    [session POST:url parameters:param1 constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

        UIImage *img = image; // response
        NSData *data = UIImagePNGRepresentation(img);

        [formData appendPartWithFileData:data name:@"imgFile" fileName:@"imgFile.png"mimeType:@"image/png"];
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject) {

        NSLog(@"success+%@", responseObject);

        //保存
        NSString *result_url_str = responseObject[@"data"];

    } failure:^(NSURLSessionDataTask * _Nonnull task, NSError * _Nonnull error) {
        NSLog(@"fail");

    }];
}

结果是：

如果我使用iOS方法上传我的图片：

数据库我们可以看到上传的图片，但是成功了，但在ImageEdit方法中，$imgs为空：

var_dump($imgs);  the `$imgs` is empty.

我的iOS应用执行：NSLog(@"fail");

如果我使用html表单提交：

<html>
<body>

<form action="Insert" method="post"
      enctype="multipart/form-data">
    <label for="file">Filename:</label>
    <input type="file" name="file" id="file" />
    <br />
    <input type="submit" name="submit" value="Submit" />
</form>

</body>
</html>

我会得到$imgs，它有上传图片的路径。

为什么我使用- (void)networkUploadHeadImage:(UIImage *)image对$imgs一无所知？

修改

如果我使用KK的答案：

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:[NSString stringWithFormat:@"%@%@",BASEURL,url] parameters:parameter constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
            if (image) {
                [formData appendPartWithFileData:UIImageJPEGRepresentation(image, 0.8) name:@"imagename" fileName:@"Image.jpg" mimeType:@"image/jpeg"];
            }

        }error:nil];

       AFURLSessionManager * urlSessionmanager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

        urlSessionmanager.responseSerializer = [AFJSONResponseSerializer serializer];
        NSURLSessionUploadTask *uploadTask;
        uploadTask = [urlSessionmanager
                      uploadTaskWithStreamedRequest:request
                      progress:^(NSProgress * _Nonnull uploadProgress) {

                      }
                      completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
                          if (error) {

                              NSLog(@"error:%@", error);
                          } else {
                           // successfully uploaded
                          }
                      }];

        [uploadTask resume];

我将打印错误信息：

但是，如果我上传像KK这样的更新方法：

UIImage *img = image;
NSData *dataObj = UIImagePNGRepresentation(img);

NSString *url = @"http://103.71.178.145:8088/Home/Aboutus/ImgEdit";

NSDictionary * param1 = @{
                          @"imgFile":dataObj
                          };


NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:url parameters:param1 constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    if (image) {
        [formData appendPartWithFileData:UIImageJPEGRepresentation(image, 0.8) name:@"imagename" fileName:@"Image.jpg" mimeType:@"image/jpeg"];
    }

}error:nil];

AFURLSessionManager * urlSessionmanager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

urlSessionmanager.responseSerializer = [AFHTTPResponseSerializer serializer];

NSURLSessionUploadTask *uploadTask;
uploadTask = [urlSessionmanager
              uploadTaskWithStreamedRequest:request
              progress:^(NSProgress * _Nonnull uploadProgress) {

              }
              completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
                  if (error) {

                      NSLog(@"err=%@", error);
                  } else {
                      // successfully uploaded
                      NSLog(@"success= %@, === %@", response, responseObject);
                  }
              }];

[uploadTask resume];

虽然我成功了，但没有得到返回网址，但PHP没有向我返回网址（图片的路径）。

请参阅我的日志：

尝试使用我的代码段下方上传图片。

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:[NSString stringWithFormat:@"%@%@",BASEURL,url] parameters:parameter constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
            if (image) {
                [formData appendPartWithFileData:UIImageJPEGRepresentation(image, 0.8) name:@"imagename" fileName:@"Image.jpg" mimeType:@"image/jpeg"];
            }

        }error:nil];

       AFURLSessionManager * urlSessionmanager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

    urlSessionmanager.responseSerializer = [AFHTTPResponseSerializer serializer];

        NSURLSessionUploadTask *uploadTask;
        uploadTask = [urlSessionmanager
                      uploadTaskWithStreamedRequest:request
                      progress:^(NSProgress * _Nonnull uploadProgress) {

                      }
                      completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
                          if (error) {


                          } else {
                           // successfully uploaded
                          }
                      }];

        [uploadTask resume];
