Parsing Plain JSON Array in Objective C [duplicate]

Answer : NSJSONSerialization.

NSJSONSerialization class can be used to convert JSON to Foundation objects and Foundation objects to JSON. In your case, you should use -JSONObjectWithData:options:error: of NSJSONSerialization class to retrieve a Foundation object from given JSON data.

Sample Code :

NSError *error;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
NSArray *fetchedArr = [json objectForKey:@"ns"];

Answer 2

The NSJSONSerialization method JSONObjectWithData:options:error can to that. You will get a dictionary with one value for the key "ns" and the value will be an array of arrays.

Answer 3

And the description shows what you are looking for

   NSError *error;
    NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];

    NSArray *fetchedArr = [json objectForKey:@"ns"];

    for (NSArray *arr in fetchedArr) {
        [arr description];
    }

Answer 4

 NSError *error = NULL;
NSData* data = [yourJsonString dataUsingEncoding:NSUTF8StringEncoding];
            NSDictionary* json = [NSJSONSerialization
                                  JSONObjectWithData:data
                                  options:kNilOptions
                                  error:&error];
NSArray *resultArray = [json objectForKey:@"ns"];//resultArray contains array type objects...

I think it will be helpful to you.
