ios - How to make UITextView hashtag link open another viewcontroller -

i using code make hashtags on app link:

import uikit  extension uitextview {  func resolvehashtags(){      // turn string in nsstring     let nstext:nsstring = self.text      // needs array of nsstring.  string not work.     let words:[nsstring] = nstext.componentsseparatedbystring(" ")      // can't set font size in storyboard anymore, since gets overridden here.     let attrs = [         nsfontattributename : uifont.systemfontofsize(17.0)     ]      // can staple urls onto attributed strings     let attrstring = nsmutableattributedstring(string: nstext string, attributes:attrs)      // tag each word if has hashtag     word in words {          // found word prepended hashtag!         // homework you: implement @mentions here too.         if word.hasprefix("#") {              // range character position, followed how many characters in word.             // need because staple "href" range.             let matchrange:nsrange = nstext.rangeofstring(word string)              // convert word nsstring string             // allows call "dropfirst" remove hashtag             var stringifiedword:string = word string              // drop hashtag             stringifiedword = string(stringifiedword.characters.dropfirst())              // check see if hashtag has numbers.             // ribl "#1" shouldn't considered hashtag.             let digits = nscharacterset.decimaldigitcharacterset()              if let numbersexist = stringifiedword.rangeofcharacterfromset(digits) {                 // hashtag contains number, "#1"                 // don't make clickable             } else {                 // set link when user clicks on word.                 // it's not enough use word "hash", need url scheme syntax "hash://"                 // note:  since it's url now, color set project's tint color                 attrstring.addattribute(nslinkattributename, value: "myapplink://\(stringifiedword)", range: matchrange)             }          }     }      // we're used textview.text     // here use textview.attributedtext     // again, wipe out fonts , colors storyboard,     // remember re-add them in attrs dictionary above     self.attributedtext = attrstring }  } 

i want make when hashtag clicked, open view controller have search page , search hashtag throughout app.

how can make connection?

what can in view controller in search hashtag, have variable can store information need.

var tag:string = "" 

then in textview

let storyboard = uistoryboard(name: "yourstoryboard", bundle: nil)         let vc:yourviewcontroller = storyboard.instantiateviewcontrollerwithidentifier("yourviewcontrollersid") as! yourviewcontroller         vc.tag = attrstring         self.presentviewcontroller(vc, animated: true, completion: nil) 

now newly presented view controller have data stored tag variable
