objective c - NSRegularExpression doesn't match -

i'm making regular look next line:

table 'joella viii' 6-max seat #4 button

so far, i've got this:

self.tabledetailsregex = [nsregularexpression regularexpressionwithpattern:@"table '[a-za-z0-9 ]*' [0-9]+-max seat #[0-9]+ button" options:nsregularexpressionallowcommentsandwhitespace error:nil]; if([self.tabledetailsregex numberofmatchesinstring:line options:nsmatchingreportcompletion range:nsmakerange(0, line.length)] == 1) { nslog(@"%@", line); }

so, regular look is:

table '[a-za-z0-9 ]*' [0-9]+-max seat #[0-9]+ button

and i'm sure selected line comes @ point, because i'm printing lines bit farther in code...

your problem in options using. nsregularexpression class reference, nsregularexpressionallowcommentsandwhitespace means whitespace , after # in regular look ignored. alternative enabled, regular look acts this:

table'[a-za-z0-9]*'[0-9]+-maxseat

you want pass 0 options, none of them enabled.

self.tabledetailsregex = [nsregularexpression regularexpressionwithpattern:@"table '[a-za-z0-9 ]*' [0-9]+-max seat #[0-9]+ button" options:0 error:nil];
