title: iOS9: Universal Links delegate not called
body: <p>I want to open the app when some http url is invoked, if the app is already installed but this delegate is never being called. I follow the link below <a href="https://support.appsflyer.com/hc/en-us/articles/207032266-Setting-Deeplinking-on-iOS9-using-iOS-Universal-Links" rel="nofollow">link</a>.       </p>
  
  <pre><code>- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void(^)(NSArray * __nullable restorableObjects))restorationHandler
  {
      if ([userActivity.activityType isEqualToString:NSUserActivityTypeBrowsingWeb]) {
          NSURL *url = userActivity.webpageURL;
          NSLog(@"url %@",url);
             [self showAlert:@"" :[NSString stringWithFormat:@"%@",[userActivity description]] shouldShow:YES];
          // do something with the URL
      }
  
      return YES;
  }
