有时我的一位用户报告说他没有收到应在何时发布的声音或横幅广告
（void）userNotificationCenter：（UNUserNotificationCenter *）center didReceiveNotificationResponse：（UNNotificationResponse *）ResponsewithCompletionHandler：（void（^）（void））completionHandler
由系统调用。我有一个内部跟踪，该跟踪可在从App Store接收到我的应用的设备上运行，并确认未调用此方法。跟踪还显示已将多个（64）通知请求发布到系统。我已经对这个问题进行了广泛的搜索，所有建议的答案都反映了我在代码中的工作。这是appDelegate中设置通知中心和委托方法的代码（省略的无关代码由三个点表示）。对于解决此问题的任何帮助，我将不胜感激。
