How do I get an NSDate from a string

Question

I am trying to get an NSDate from a string. The problem I am having is that the date I need is within a text.

Example: “Expieres : 26 May 2015 140 days left”.

I would like “26 May 2015” out of that and convert it into an NSDate. Would I use Regular expression, then convert the string to NSDate. If so, what would the regular expression look like.

Any help would be appreciated, thanks in advance.

`@"\\d{2} [A-Za-z]+ \\d{4}"` This is extremely lax regex. Your single example is not enough to tell whether you need a stricter one. — nhahtdh, Jan 06 '15 at 13:46
@nhahtdh, you should post your reply as an answer so the OP can accept it. — Duncan C, Jan 06 '15 at 13:47
@DuncanC: This is another uninteresting and underspecified question. Sorry, but I don't care enough to post an answer. — nhahtdh, Jan 06 '15 at 13:48

There are gazillion ways to match the date. Depending on the actual input and purpose, you may or may not need a strong regex to match what you want.

One simple solution (while reasonably strict) is:

@"\\d{2} [A-Za-z]+ \\d{4}"
