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.
