<img src="https://s3-ap-northeast-1.amazonaws.com/mtl-link-label/ib1.png" width="258">#####Change UILabels custom class to 'LinkLabel', and Change module to 'MTLLinkLabel'.
<img src="https://s3-ap-northeast-1.amazonaws.com/mtl-link-label/ib2.png" width="259">You must change labels userInteractionEnabled property to true. Because, this labels properties default value is false.

Add custom link
You can add custom link in LinkLabel with range and Action at the time of the link selection.
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://") ? "http://" + text : text
guard let url = NSURL(string: httpText) else { return }
UIApplication.sharedApplication().openURL(url)
}
else if result.resultType.contains(.PhoneNumber) {
let telURLString = "tel:" + text
UIApplication.sharedApplication().openURL(NSURL(string: telURLString)!)
}
}
func linkAttributeForLinkLabel(linkLabel: LinkLabel, checkingType: NSTextCheckingType) -> [String: AnyObject] {
return [
NSForegroundColorAttributeName: linkLabel.tintColor,
NSUnderlineStyleAttributeName: NSUnderlineStyle.StyleSingle.rawValue
]
}
func linkDefaultAttributeForCustomeLink(linkLabel: LinkLabel) -> [String: AnyObject] {
return [
NSForegroundColorAttributeName: linkLabel.tintColor,
NSUnderlineStyleAttributeName: NSUnderlineStyle.StyleSingle.rawValue
]
}
func linkLabelCheckingLinkType() -> NSTextCheckingTypes {
return NSTextCheckingType.Link.rawValue
| NSTextCheckingType.PhoneNumber.rawValue
}
}
