【问题描述】：

我所有的 AFNetworking 服务都是用单独的 web 服务类编写的。到目前为止，我在传递 NSDictionary 参数方面做得很好。但是现在当我需要将 NSData 文件传递​​给 Web 服务时遇到了问题。

我是如何执行网络服务的

 NSData *imageData = UIImageJPEGRepresentation(self.profileImg.image, 0.5); // I need to pass this imageData

    NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"yyyy-MM-dd hh:mm:ss"];

    NSString *stringFromDate = [dateFormatter stringFromDate:[NSDate date]];

    //Encrypting Password
    NSString *passwordString = _password.text;
    NSString *passwordMD5 = [passwordString MD5String];

    NSDictionary *params = @@"username": _username.text,
                             @"password": passwordMD5,
                             @"email": _email.text,
                             @"date":stringFromDate;

    WebService *serviceObj = [[WebService alloc] init];
    serviceObj.delegate = self;
    [serviceObj performSelectorInBackground:@selector(doRegister:) withObject:params];

这里我是如何编写网络服务的

NSMutableDictionary * parameters = [[NSMutableDictionary alloc]initWithDictionary:params];

NSURL *baseURL = [NSURL URLWithString:@"http://www.example.com/register.php"];

AFHTTPSessionManager * manager = [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL];
manager.responseSerializer = [AFJSONResponseSerializer serializer];

[manager POST:@"" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) 

    [formData appendPartWithFileData:imageData name:@"image" fileName:@"profile.png" mimeType:@"image/png"];

 progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) 

    [delegate didReceiveRegisterResponse:responseObject];

 failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) 

];

但我现在不知道如何分配该图像数据。

【参考方案1】：

我已经在数组中传递了 NSData 和 NSDictionary。如下所示

[self performSelectorInBackground:@selector(reloadPage:)
                       withObject:[NSArray arrayWithObjects:pageIndex,firstCase,nil] ];


- (void) reloadPage: (NSArray *) args 
    NSString *pageIndex = [args objectAtIndex:0];    
    NSString *firstCase = [args objectAtIndex:1];
