当使用新的通知机制点击本地通知时，如何打开应用程序？

Question

application:didReceiveLocalNotification: 从 iOS10 开始被弃用，developer page 没有指向任何替代方案。

UNNotificationRequest* request = [UNNotificationRequest requestWithIdentifier:@"localnotification"
                                                                      content:content
                                                                      trigger:trigger];


UNUserNotificationCenter* notificationCenter = [UNUserNotificationCenter currentNotificationCenter];
[notificationCenter requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
                                  completionHandler:^(BOOL granted, NSError * _Nullable error) {
                          if (!error) {
                              NSLog(@"request authorization succeeded!");
                          }
                      }];


[notificationCenter addNotificationRequest:request
                     withCompletionHandler:nil];

我已经创建了一个如上所示的通知，其中包含适当的内容和触发器。现在我希望应用程序在我点击通知时打开，但我似乎无法弄清楚如何。

userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler:

如果要执行自定义操作，则需要实现 UNUserNotificationCenterDelegate 中的此方法。

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {
    if ([response.actionIdentifier isEqualToString:UNNotificationDefaultActionIdentifier]) {
        NSLog(@"app opened");
    }
}
