ios - TTTAttributedLabel didSelectLink 未在 swift 4.0 中调用

Question

我使用 TTTAttributedLabel，这是我的代码。当我单击链接变得金光闪闪时，但 attributeLabel(_ label: TTTAttributedLabel!, didSelectLinkWith url: URL!) 没有调用。任何人都可以帮助我。我都这样为标签设置了委托(delegate)。你能帮我一下吗？

 import TTTAttributedLabel
   class MainVC : UIViewController,TTTAttributedLabelDelegate{

 @IBOutlet weak var lblTerms: TTTAttributedLabel!

  func setupMultipleTapLabel() {
    let str = "By signing up, I agree to \(APPNAME_AND_VERSION_ABOUT.capitalized)'s Terms of Service, Privacy Policy, Guest Refund Policy, and Host Gurantee Terms." as NSString
    lblTerms.text = str as String
    lblTerms.delegate = self
    let range : NSRange = str.range(of: "Terms of Service")
    lblTerms.addLink(to: NSURL(string: "\(WebServerUrl)terms_of_service")! as URL?, with: range)
    let range1 : NSRange = str.range(of: "Privacy Policy")
    lblTerms.addLink(to: NSURL(string: "\(WebServerUrl)privacy_policy")! as URL?, with: range1)
    let range2 : NSRange = str.range(of: "Guest Refund Policy")
    lblTerms.addLink(to: NSURL(string: "\(WebServerUrl)guest_refund")! as URL?, with: range2)
    let range3 : NSRange = str.range(of: "Host Gurantee Terms")
    lblTerms.addLink(to: NSURL(string: "\(WebServerUrl)host_guarantee")! as URL?, with: range3)
  }
  func attributedLabel(_ label: TTTAttributedLabel!, didSelectLinkWith url: URL!) {
    print("url \(url)")
    UIApplication.shared.openURL(url)
   }
}

我明白了..它工作正常...我使用 tab guster。所以我去掉了风口，它工作正常。
