是否可以在显示NSLocalNotification之前和安排之后修改NSLocalNotification的警报正文？

Question

这是我的代码，用于安排 UILocalNotificaiton 并每分钟重复一次：

UILocalNotification *localNotification = [[UILocalNotification alloc] init];

localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:delay];
localNotification.alertAction = nil;
localNotification.soundName = UILocalNotificationDefaultSoundName;

localNotification.alertBody = @"Initial message";
localNotification.alertAction = NSLocalizedString(@"Return to App", nil);
localNotification.repeatInterval = NSCalendarUnitMinute;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

通知触发后，我想更改警报正文（标题等）以反映此通知被触发的次数。

这是我的代码：

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif
{
    notif.soundName = UILocalNotificationDefaultSoundName;
    notif.alertBody = @"Changing body"; //This is where I will put the count
}

然而，身体不会改变。

不要记得，但它不包含setAlertBody方法吗？
