iOS NotificationContent Extension 相关问题

NotificationContent Extension 注册了几个action,在app未启动时,收到push,点击action打开
app,会走哪个方法?

注意是app未启动
现象是会调用:

 -(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler

但是有时会调有时不会调, 什么原因,

categoryIdentifier没有匹配吧

app通讯的那个标识可能跟其它有重复
