How to create json Object with NSData in Objective C?

Question

How to create json Object with NSData in Objective C. I'm having values in a NSData variable.

Answer 1

You can use it like this in iOS 5 (if you are sure of your json structure you can directly use NSArray or NSDictionary doing a cast)

NSError *jsonError;
id jsonDictionaryOrArray = [NSJSONSerialization JSONObjectWithData:myData options:NULL error:&jsonError];
if(jsonError) {
    // check the error description
    NSLog(@"json error : %@", [jsonError localizedDescription]);
} else {
    // use the jsonDictionaryOrArray
}
