swift - Click on keyword in UILabel -

my following code in swift.

to sum up, have uitableview tweets, each row tweet. can know hashtags king of code :

for hashtag in tweet.hashtags {     attributedtext.setattributes(hashtagattrs, range: hashtag.nsrange) } 

but useful if want highlight these keywords (hashtags)

to put text of tweet in label, write :

@iboutlet weak var tweettextlabel: uilabel! tweettextlabel?.text = tweet.text 

so have tableview

what want able click on hashtag , research same information new hashtag. ask : how can click on hashtag, directly in label ?

thank much!

[update]

i succeed access hashtag uitextview instead of uilabel, code :

func textview(textview: uitextview, shouldinteractwithurl url: nsurl, inrange characterrange: nsrange) -> bool {         let tweettableview = tweettableviewcontroller()     tweettableview.searchtext = url.absolutestring     return true } 

but problem can't reload data in tableview. have new tweets in tweet variable, cell doesn't update. function tableview never called!

override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {     let cell = tableview.dequeuereusablecellwithidentifier(storyboard.cellreuseidentifier, forindexpath: indexpath) as! tweettableviewcell     cell.tweet = tweets[indexpath.section][indexpath.row]     return cell } 

i've tried

tableview.delegate = self 

i use function refresh tableview, self.tableview.reloaddata() nothing ...

@ibaction func refresh(sender: uirefreshcontrol?) {     if searchtext != nil {         if let request = nextrequesttoattempt {             request.fetchtweets { (newtweets) -> void in                 dispatch_async(dispatch_get_main_queue()) { () -> void in                     if newtweets.count > 0 {                         self.lastsuccessfulrequest = request                         self.tweets.insert(newtweets, atindex: 0)                         self.tableview.reloaddata()                     }                     sender?.endrefreshing()                 }             }         }     } else {         sender?.endrefreshing()     } } 

hint :

maybe it's because use instance of class here ? should call parent tableview of tableviewcell ? how ?

 func textview(textview: uitextview, shouldinteractwithurl url: nsurl, inrange characterrange: nsrange) -> bool {         let tweettableview = tweettableviewcontroller()     tweettableview.searchtext = url.absolutestring     return true } 

[update & close]

i succeed delegate : problem used instance of tableviewcontroller.

// tableviewcell protocol tweettableviewcelldelegate  { // delegate     func updatetweethashtag(tweettableviewcell) }  // tableviewcontroller  func updatetweethashtag(cell: tweettableviewcell){     let newhashtag = cell.newhashtagincell     searchtext = newhashtag } 

i don't think uilabels support clickable urls. you'll need use uitextviews that, , implement appropriate delegate methods.
