Url correct but the dictionary is null - ios

Question

I have to download data using JSON, the url is correct (tested on chrome) but I get an empty dictionary. Where did I go wrong?
NSLog(#"'url is %#", stringUrl); //correct
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:stringUrl]];
NSHTTPURLResponse __autoreleasing *response = nil;
NSError __autoreleasing *error = nil;
NSData *result = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
// the result is:
/* <280d0a0d 0a0d0a0d 0a0d0a0d 0a0d0a7b 22636f6d 6d6f6e22 3a7b2261 636b223a

.......*/
NSString *str = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];
NSLog(#" STRING IS %#", str);
//the string is correct
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSLog (#"The parser is %#", parser);
//The parser is <SBJsonParser: 0x8877400>
NSDictionary *object = [parser objectWithData: result];
NSLog(#" The dictionary is %#", object);// The dictionary is null
The result of string:
NSString *str = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];
NSLog(#" THE STRING IS %#", str);
/* ({"common":
{"ack":"OK",
"faultCode":null,
"faultString":null},

I put the formatting so to be readable, in fact the returned data is all on one line

There is a "(" and ")" at the starting and ending of the JSON response when you try to cast it in a NSDictionary or NSArray, it doesnt recognize it and hence goes empty. So to get it parsed you'll need to add this:
str = [[str stringByReplacingOccurrencesOfString:#"(" withString:#""] stringByReplacingOccurrencesOfString:#")" withString:#""];
before
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSLog (#"The parser is %#", parser);
//The parser is <SBJsonParser: 0x8877400>
NSDictionary *object = [parser objectWithData: result];
NSLog(#" The dictionary is %#", object);// The dictionary is null
