I wanted to make an app through which we can check our Railway PNR Reservation status and if possible we can do railway Enquiry also but main part is PNR status.

谁能告诉我如何开始? 是否必须为此执行任何计划,如果是的话?

<>UPDATED>:

实际上,一看网站的源代码是怎样做的,一则发现一个链接,在JSON......提供产出。

{ status : OK , data : { passenger : [{ status : RAC 44 , seat_number : W/L 8,RLGN }], from : PUNE , alight : DMN , pnr_number : 8162588905 , train_number : *11039 , to : DMN , board : PUNE , train_name : MAHARASHTRA EXP , travel_date : { date : 1-12-2011 , timestamp : 1322697600}, class : SL }}

I dont知道如何教化JSON,因为我只知道NSXMLParser...... 我看到了许多联系,但要么一米不正确,要么不理解。任何人都能够这样做,并向我解释。我将非常感谢他。

请访问。

电话请上。

答复将采用JSON格式。

Edit:

NSString *jsonString = @"{ status :....}";
SBJsonParser *jsonParser = [[SBJsonParser alloc] init];
NSError *error = nil;
id jsonObject = [jsonParser objectWithString:jsonString error:&error];
[jsonParser release]; jsonParser = nil;
if ([jsonObject isKindOfClass:[NSDictionary class]])
{
   NSDictionary *dict = jsonObject;
   NSString *status = [dict objectForKey:@"status"];
   NSDictionary *data = [dict objectForKey:@"data"];
   NSArray *passengers = [data objectForKey:@"passenger"];

   //similarly do it for other members
}
