Subject: [PATCH] regex to not detect hashtag after a character not space

I am trying to scan for hashtags from NSStrings in Objective-C and I am using regex.
I made a test status on Facebook / Instagram to see what are the valid hashtags as it is where

Now KILabel.m (getRangeForHashTags line : 437)

regex = [[NSRegularExpression alloc] initWithPattern:@"(?<!\\w)#([\\w\\_]+)?" options:0 error:&error];
My Solution (It's works fine. when not space)

regex = [[NSRegularExpression alloc] initWithPattern:@"((#)([\\w\\_]+)?)" options:0 error:&error];
Thanks.
