Assuming you're on iOS you can check that using NSDataDetector

You could use a NSDateFormatter and allow it to use an heuristic to determine if the given input string is a date or not (just call [formatter setLeninent:YES] for this). If it can create a NSDate object out of your NSString, congratulations, the string contains a date, otherwise it most likely doesn't.

You can try creating a new NSDate instance giving the NSString and check wether the result is nil or not.

NSDate

That will only work if the date is in a specific format sadly. – Joshua Weinberg Jul 14 '11 at 14:36
