Get NSDate from JSON Date format Date1268123281843

suggest change

Prior to Json.NET 4.5 dates were written using the Microsoft format: “/Date(1198908717056)/”. If your server sends date in this format you can use the below code to serialize it to NSDate:

Objective-C 

(NSDate*) getDateFromJSON:(NSString *)dateString
{
    // Expect date in this format "/Date(1268123281843)/"
    int startPos = [dateString rangeOfString:@"("].location+1;
    int endPos = [dateString rangeOfString:@")"].location;
    NSRange range = NSMakeRange(startPos,endPos-startPos);
    unsigned long long milliseconds = [[dateString substringWithRange:range] longLongValue];
    NSLog(@"%llu",milliseconds);
    NSTimeInterval interval = milliseconds/1000;
    NSDate *date = [NSDate dateWithTimeIntervalSince1970:interval];
    // add code for date formatter if need NSDate in specific format.
    return date;
}
