Regex pattern appearing infinite times

I'm looking for the regex pattern of three spaces followed by any sequence of numbers followed by a period and then a space. I have achieved almost this result, except that my regex doesn't allow for any number of numbers, just one number:

NSRange range = [newString rangeOfString:@"  [0-9]\\. " options:NSRegularExpressionSearch];

How can I make it detect any number of numbers 0-9?

You can use the following regular expression.

@" {3}[0-9]+\\. "

Explanation:

 {3}            # ' ' (3 times)
[0-9]+          # any character of: '0' to '9' (1 or more times)
\.              # '.'
                # ' '

Just add the + quantifier after the character class

@"  [0-9]+\\. "

Also MJB noted that your regex, as posted, only shows two spaces at the beginning. Was there an error in your regex? Or in your description?
