Add custom link
You can add custom link in LinkLabel with range and Action at the time of the link selection.
Void in let alert = UIAlertController(title: nil, message: url.absoluteString, preferredStyle: UIAlertControllerStyle.ActionSheet) alert.addAction(UIAlertAction(title: "Go", style: .Default, handler: { (action) -> Void in UIApplication.sharedApplication().openURL(url) })) alert.addAction(UIAlertAction(title: "Cancel", style: .Default, handler: nil)) self.presentViewController(alert, animated: true, completion: nil) }">
let range = (text as NSString).rangeOfString("1829") cell.label.addLink( NSURL(string: "https://www.google.co.jp/#q=1829")!, range: range, linkAttribute: [ NSForegroundColorAttributeName: UIColor.redColor(), NSUnderlineStyleAttributeName: NSUnderlineStyle.StyleSingle.rawValue ] ) { (url) -> Void in let alert = UIAlertController(title: nil, message: url.absoluteString, preferredStyle: UIAlertControllerStyle.ActionSheet) alert.addAction(UIAlertAction(title: "Go", style: .Default, handler: { (action) -> Void in UIApplication.sharedApplication().openURL(url) })) alert.addAction(UIAlertAction(title: "Cancel", style: .Default, handler: nil)) self.presentViewController(alert, animated: true, completion: nil) }

Delegate
LinkLabelDelegate methods are optional method.
The default implementation is implemented in protocol extension.

public extension LinkLabelDelegate { func linkLabelExecuteLink(linkLabel: LinkLabel, text: String, result: NSTextCheckingResult) -> Void { if result.resultType.contains(.Link) { let pattern = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]+" if NSPredicate(format: "SELF MATCHES '\(pattern)'").evaluateWithObject(text) { UIApplication.sharedApplication().openURL(NSURL(string: "mailto:" + text)!) return } let httpText = !text.hasPrefix("http://") && !text.hasPrefix("https://") ?
