Question

I need to send some details to a server from my iphone app.

I have details as separate arrays of ID,name,quantity and strings with name,address,phone & email.

I need to change the NSmutable array data into this JSON format

      [
            {"id":"139","name":"Samosa","quantity":"332","spice":"hot"},
            {"id":"149","name":"rice","quantity":"4","spice":"mild"},
            .....
      ]

My one doubt is
[request setHTTPMethod:@"POST"];
Is the above line is enough to set the POST request.

How could I add the above details into the POST request?

Use a JSON serializer. You could use SBJSON. With SBJSON, the code will be like this:

SBJsonWriter *jsonWriter = [[[SBJsonWriter alloc] init] autorelease];
NSString *jsonParams = [jsonWriter stringWithObject:<your-NSArray>];

For adding this jsonParams to POST:

NSString *postData = [jsonParams stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:postURL];
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setHTTPBody:[postData dataUsingEncoding:NSUTF8StringEncoding]];
