JSON响应显示在提醒vview中？

我对iphone开发很陌生我有一个需求，比如我需要在alert视图中显示JSON响应（例如：我有一个登录页面，当我提供错误的细节时，我正在从服务器获取响应，我需要在alert视图中显示响应）这里我的代码是JSON响应显示在提醒vview中？

-(IBAction)signin:(id)sender{ 

      requestSelect = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString: @"http://abc....?"]]; 



      NSString *requestString = [NSString stringWithFormat:@"request_parameter={\"EmailId\":\"%@\", \"Password\":\"%@\"}",email.text,password.text,nil]; 

      NSLog(@"requestString in subarea %@",requestString); 
      NSMutableData *requestData =[NSMutableData dataWithBytes: [requestString UTF8String] length: [requestString length]]; 

      [requestSelect setHTTPMethod: @"POST"]; 

      [requestSelect setHTTPBody: requestData]; 

      connection=[[NSURLConnection alloc] initWithRequest:requestSelect delegate:self]; 



       } 

       - (void)connection:(NSURLConnection *)connection didReceiveResponse:   (NSURLResponse  *)response{ 
       receiveddata = [[NSMutableData alloc]init ]; 
      } 
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)aData{ 
       [ receiveddata appendData:aData]; 
} 

- (void)connectionDidFinishLoading:(NSURLConnection *)connection{ 

        jsonString = [[NSString alloc] initWithData:receiveddata 
               encoding:NSUTF8StringEncoding]; 
      dictServerData = [jsonString JSONValue]; 

      valueForKey:@"result"]valueForKey:@"data"] objectAtIndex:0]valueForKey:@"service_status" ]); 


      arr_login= [[NSArray alloc]initWithArray:[[[[[dictServerData valueForKey:@"webservice"] valueForKey:@"result"]valueForKey:@"data"] objectAtIndex:0]valueForKey:@"service_status" ]]; 


      objectForKey:@"webservice"]objectForKey:@"result"]objectForKey:@"data"]objectAtIndex:0]objectForKey:@"userdetails" ]objectAtIndex:0]); 



       NSMutableDictionary *DetailsDict=[NSMutableDictionary dictionaryWithObject:[ [[[[[dictServerData    objectForKey:@"webservice"]objectForKey:@"result"]objectForKey:@"data"]objectAtIndex:0]objec   tForKey:@"userdetails" ]objectAtIndex:0] forKey:@"data"]; 

      NSLog(@"details dict : %@",DetailsDict); 



      defaults = [NSUserDefaults standardUserDefaults]; 
      [defaults setObject:DetailsDict forKey:@"details"]; 

      UpdateDetail *updt =[[UpdateDetail alloc]initWithNibName:@"UpdateDetail" bundle:Nil]; 
      [self.navigationController pushViewController:updt animated:YES]; 
      [updt release]; 



}

究竟什么是你问的JSON响应？如何用消息显示警报视图？ – giorashc

是的，我想显示服务器响应像登录错误或注册成功。 – feroz

如果你只是想显示一条消息，警报视图请执行以下操作：

UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"Your Title" 
              message: @"Your message" 
            delegate: nil 
            cancelButtonTitle:@"OK" 
            otherButtonTitles:nil]; 
[alert show]; 
[alert release];

这将打开一个模式警报视图（即无接触传递低谷直到你点击OK按钮。

所以只是把信息（如果需要将其转换为可读的字符串）

我不想显示静态响应，我需要显示在服务器 – feroz

我得到的警报respose比使用从服务器获得的响应对象。如有必要，将其转换为字符串 – giorashc
