Parse nsstring json valuses in iphone?

Question

I have JSon Values in NSString. I am trying to parse the values from the NSString JSonValue.

NSString Values like:

result = [{"no":"01","send":"2010-05-03 01:26:48","from":"0000000000","to":"1111111111","text":"abcd"}]

I have tried the below code to parse the values no, send, from, to, text.

 NSString *jsonString = result; NSDictionary *jsonArray = [jsonString jsonValue]; //Am trying to save the values from NSString to NSDictionary the app getting crash here. NSLog(@"JsonDic : %@", jsonArray);

Can anyone please help to parse the JSon values from NSString? Thanks in advance.

So you have searched stackoverflow and couldn't find any questions about how to parse JSON on iOS? Very strange... — Paul de Lange

For iOS5, you can use NSJSONSerialization.

NSError *error; NSString *json = @"[{\"no\":\"01\",\"send\":\"2010-05-03 01:26:48\",\"from\":\"0000000000\",\"to\":\"1111111111\",\"text\":\"abcd\"}]"; id jsonObj = [NSJSONSerialization JSONObjectWithData:[json dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingAllowFragments error:&error];

And you can also use SBJson.

Thanks for your response. I have solved the problem and i can get the values. Thanks for your help.

Gopinath. I have mentioned code please try this one. I have tested i can get the no.

SBJSON *parser = [[SBJSON alloc] init]; NSDictionary *jsonArray = (NSDictionary *) [parser objectWithString:result error:nil]; NSLog(@"jsonArray : %@", jsonArray); NSArray *depositArray = [jsonArray valueForKey:@"no"]; NSLog(@"depositArray : %@", depositArray);

Please test and let me know if you face any problem. Thanks.

Parsing JSON is a bit more complicated.

For my part, i use SBJSON, you can download it from here : http://stig.github.com/json-framework/

It is a simple set of file to put in your project. I suggest to put in a dedicated group.

Once you've done that, here is the code you could use :

NSError *jsonError; NSDictionary *jsonResults; SBJsonParser* parser = [[SBJsonParser alloc]init]; jsonResults = [parser objectWithString:YOURSTRING error:&jsonError ]; if (jsonResults == nil) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:[NSString stringWithFormat:@"Something bad happened with JSON : %@ : %@",YOURSTRING,[ jsonError localizedDescription ]] delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alertView show]; [alertView release]; } else { NSLog(@"JSON result : %@",jsonResults); }

If you need more infos, you can find good tutorial on SBJSon, for instance here : http://www.touch-code-magazine.com/tutorial-fetch-and-parse-json/
