//Access to the PTMediaPlayerItem
PTMediaPlayerItem *item = self.player.currentItem;
PTNotificationHistory *notificationHistory = item.notificationHistory;
//Create notification
PTNotification* notification = [[PTNotification notificationWithType:PTNotificationTypeWarning code:99999 description:@"Custom notification description"];
//Add notification
[notificationHistory addNotification:notification];
