[Solved] Objective C: split text between brackets

Question

You can solve this problem using a regular expression and NSRegularExpression.

Construct a pattern which matches the text between brackets. For example the pattern @"\\[([^]]*)]" matches an opening bracket \\[ – the backslash is required to treat the bracket as a literal character, zero or more characters except a closing bracket [^]]*, groups that text so it referred to ([^]]*), and a closing bracket ]. You can build up a pattern which matches comma separated sequences of bracket text, or just look for multiple matches of bracketed text – depending on your requirements.

Once you’ve created your regular expression, using the methodregularExpressionWithPattern:options:error:, the method matchesInString:options:range: can be used obtain an array of all the matches. You can process this array to produce your required array of strings.
