Remember that you need iOS 4.0 or higher to use this:

 NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"points:\\\"([^\\\"]*)\\\"" options:0 error:NULL]; NSTextCheckingResult *match = [regex firstMatchInString:apiResponse options:0 range:NSMakeRange(0, [apiResponse length])]; NSString *encodedPoints = [apiResponse substringWithRange:[match rangeAtIndex:1]]; 

Hope this helps.
