需要做的自定义处理

- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
    self.contentHandler = contentHandler;
    self.bestAttemptContent = [request.content mutableCopy];
    

    
    self.contentHandler(self.bestAttemptContent);
}

- (void)serviceExtensionTimeWillExpire {
    // Called just before the extension will be terminated by the system.
    // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
    self.contentHandler(self.bestAttemptContent);
}

如果需要做http网络请求，需要TestNotificationServiceExtension 里面的Info添加App Transport Security Settings

TestNotificationServiceExtension的Info和项目里的数据不互通
如果需要跟项目里的数据互通需要创建App Groups

参考 App Groups 创建 https://www.jianshu.com/p/3fbaa8143a75?v=1675044627433
