Ios 计划本地通知问题-每日发射问题

我在AppDelegate上为我的通用应用程序设置了多个本地通知，确切地说是14。这些通知具有特定的时间和工作日，它们应该在这些时间和工作日发出

问题是所有这些通知每天都会发出

例如，我有一个周六早上的通知，但它每天都会出现

请给我一个建议或指示，为什么我的通知每天都被解雇？我似乎找不到解决办法

请查看我的代码，谢谢

谢谢

这些行导致通知每天重复一次：

notification.repeatInterval = NSWeekdayCalendarUnit;

删除这些行，它将解决您的问题。用户可以确切地说明此属性的功能：

如果您指定了日历单位，例如每周（NSWeekCalendarUnit）或每年（NSYearCalendarUnit），则系统会重新安排通知以指定的时间间隔发送。默认值为0，表示不重复

要在一周中的特定日期和特定时间发出通知，应使用以下代码：

NSCalendar *gregCalendar = [[NSCalendar alloc]initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *dateComponent = [gregCalendar components:NSYearCalendarUnit  | NSWeekCalendarUnit fromDate:[NSDate date]];

[dateComponent setWeekday:2]; // For Monday
[dateComponent setHour:11];
[dateComponent setMinute:44];

NSDate *fireDate = [gregCalendar dateFromComponents:dateComponent];

UILocalNotification *notification = [[UILocalNotification alloc]init];
[notification setAlertBody:@"GOOD MORNING!"];
[notification setFireDate:fireDate];
notification.repeatInterval = NSWeekCalendarUnit;
[notification setTimeZone:[NSTimeZone defaultTimeZone]];
[[UIApplication sharedApplication] scheduleLocalNotification:notification];

第一部分计算下一个星期一或上一个星期一的日期。 第二部分定义了重复间隔为一周的通知

---

无论火灾日期是否为前一个星期一，“下一个火灾日期”将自动调整为下周。（您可以验证使用

NSLog（@“%@”，notification）

）

在一周中的特定日期和特定时间发出通知时，以下代码应起作用：

NSCalendar *gregCalendar = [[NSCalendar alloc]initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *dateComponent = [gregCalendar components:NSYearCalendarUnit  | NSWeekCalendarUnit fromDate:[NSDate date]];

[dateComponent setWeekday:2]; // For Monday
[dateComponent setHour:11];
[dateComponent setMinute:44];

NSDate *fireDate = [gregCalendar dateFromComponents:dateComponent];

UILocalNotification *notification = [[UILocalNotification alloc]init];
[notification setAlertBody:@"GOOD MORNING!"];
[notification setFireDate:fireDate];
notification.repeatInterval = NSWeekCalendarUnit;
[notification setTimeZone:[NSTimeZone defaultTimeZone]];
[[UIApplication sharedApplication] scheduleLocalNotification:notification];

验证重复间隔必须使用NSWeekCalendarUnit，而不是NSWeekdayCalendarUnit，请参见。谢谢Martin，因此我应该将其设置为：

notification.repeatInterval=NSWeekCalendarUnit用于每个通知，但如何在我的
NSDateComponents
中声明它？有必要吗？谢谢重复间隔必须使用NSWeekCalendarUnit，而不是NSWeekdayCalendarUnit，请参见。谢谢Martin，因此我应该将其设置为：

[[UIApplication sharedApplication]cancelAllLocalNotifications]
）？谢谢Martin。运行了一些测试，通知按计划启动@esierr：好的，我很高兴它起到了作用。嗨，Martin，我实现了对代码的这些更改，但是我仍然有同样的问题。例如，该应用程序刚刚启动了计划在周五和周六发布的通知。我做错了什么？在安排新设置之前，您是否取消了所有旧通知（
