iOS：将NSObject类中soap webservice解析的值传递回UIViewController

我不知道为什么这么难，但我不能让它工作。这是我的简单问题：

我有一个

UIViewController

，它调用执行解析任务的

NSObject

类的paring类类型

我只需要将解析后的数据值返回到

ViewController

有谁能为我提供一个简单的步骤或任何建议来做到这一点。。。 我真的需要为我的项目解决这个问题，最后期限快到了

谢谢 这是我的密码：

您可以在NSObject类中创建协议，在所有解析操作完成后触发协议，并将视图控制器设置为代理。

请参阅下面的步骤

1）在NSOBject类中，比如说

ParsingModel

类，在进行解析的解析类中创建协议。随便你叫什么名字都行

   @protocol  WebServiceResponseDelegate <NSObject>

   @optional
  - (void)didRecieveResponseData:(NSMutableArray*)array;

  @end

只需要将解析后的数据发送到确认类，即从中创建解析对象

   //say didRecieveResponse this is the method called when you completed parsing of data

 // - (void)didRecieveResponse
  // {   
  //  if([delegate respondsToSelector:@selector(didRecieveResponseData)])
 //    {
  //    //pass populated dataSource which would have the Parsed Data.

  //    [delegate didRecieveResponseData:parsedData];
 //    //  parsedData is the NUMtableArray or any other DataSource.

  //}

编辑：下面是成功完成配对时调用的

委托

方法

  - (void)parserDidEndDocument:(NSXMLParser *)parser{
    //pass populated dataSource which would have the Parsed Data.  

    //before check whether that delegate method confirmed by the class.

    if([delegate respondsToSelector:@selector(didRecieveResponseData)])
     {
       [delegate didRecieveResponseData:parsedData];
     }

   //  parsedData is the NUMtableArray or any other DataSource.

   }
  // called when the parser has completed parsing. If this is encountered, the parse was successful.you need to call

2）并在确认类中，如您所说的

UIViewController

say

DataViewController

定义该委托方法 在您的

DataViewController.h

中，采用像这样的协议

DataViewController

并从创建解析模型类的位置设置

Delegate

像这样

  ParsingModel * paring = [ParsingModel alloc]init];
  [paring setWebServiceResponseDelegate:self];

 //definition of callback delegate method
 - (void)didRecieveResponseData:(NSMutableArray*)array
 {
 //here you would have the Parsed Data now you can use it as you want

 }

---

我希望您一切都清楚。

只需使用函数从该类返回值即可：-）谢谢Kamarshad，我已经编辑了我的线程并粘贴了我的代码，请查看一下并告诉我在代码中的更改位置。。。重新考虑我当前使用的代码，告诉我如何应用协议。@Mr.KLD查看我的编辑，更改代码。如果您仍然不理解，我将无法进一步帮助您。实际上，在S/O上，我们讨论逻辑，而不是提供完整的运行代码。以及我认为您在寻找完整的运行代码。男人只要看看代码，试着从中得到一些想法。

  ParsingModel * paring = [ParsingModel alloc]init];
  [paring setWebServiceResponseDelegate:self];

 //definition of callback delegate method
 - (void)didRecieveResponseData:(NSMutableArray*)array
 {
 //here you would have the Parsed Data now you can use it as you want

 }
