【中文标题】本地通知“每天早上 7:00”未通知

【英文标题】：Local Notification "Everyday at 7:00am" not notifying

【发布时间】：2012-11-08 19:21:20

【问题描述】：

我希望每天 7:00 发出通知，但它不会发出。我也希望它显示在锁定屏幕中。这是我到目前为止的所有代码。

-(void)EveryDayNotify



    NSLog(@"Good Morning Working");

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


    [localNotification setAlertBody:@"Good Morning! Have a great day!"];
    localNotification.soundName = UILocalNotificationDefaultSoundName;
    localNotification.applicationIconBadgeNumber = 1;

    localNotification.repeatInterval = NSDayCalendarUnit;

    NSCalendar *calendar = [NSCalendar currentCalendar]; // gets default calendar
    NSDateComponents *components = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit) fromDate:[NSDate date]]; // gets the year, month, day,hour and minutesfor today's date
    [components setHour:07];
    [components setMinute:0];

    localNotification.fireDate = [calendar dateFromComponents:components];


    [localNotification release];

【参考方案1】：

尝试使用这个：

- (void)applicationDidEnterBackground:(UIApplication *)application 


NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];

NSDateComponents *componentsForReferenceDate = [calendar components:(NSCalendarUnitDay | NSCalendarUnitYear | NSCalendarUnitMonth ) fromDate:[NSDate date]];

[componentsForReferenceDate setDay:9];
[componentsForReferenceDate setMonth:11];
[componentsForReferenceDate setYear:2012];

NSDate *referenceDate = [calendar dateFromComponents:componentsForReferenceDate];

// set components for time 7:00 a.m.

NSDateComponents *componentsForFireDate = [calendar components:(NSCalendarUnitYear | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond ) fromDate: referenceDate];

[componentsForFireDate setHour:7];
[componentsForFireDate setMinute:0];
[componentsForFireDate setSecond:0];

NSDate *fireDateOfNotification = [calendar dateFromComponents:componentsForFireDate];

// Create the notification

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

notification.fireDate = fireDateOfNotification;
notification.timeZone = [NSTimeZone localTimeZone];
notification.alertBody = [NSString stringWithFormat: @"Good Morning! Have a great day!"];
notification.alertAction = @"go back";
notification.userInfo= @@"information": [NSString stringWithFormat:@"Some information"];
notification.repeatInterval= NSCalendarUnitDay;
notification.soundName = UILocalNotificationDefaultSoundName;
notification.applicationIconBadgeNumber = 1;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];

【讨论】：

componentsForReferenceDate 是什么？

好吧，让我们说你的 setMonth: 11 意味着在 11 月调用了 fireate，对于其他人来说，同样的事情我已经为你设置了代码，这就是你想要的

好的，现在只需将整个代码复制并粘贴到您的应用委托中

所以我不应该担心 componentsForReferenceDate 吗？

只需将 NSDaycalenderunit 设置为 NSMinuteCalenderunit，它就会每分钟和你设置的秒数弹出

【参考方案2】：

你需要打电话

[[UIApplication sharedApplication] scheduleLocalNotiication:localNotification];

在您发布 localNotification 之前。您的代码完成了所有设置，但实际上并没有安排它，这就是为什么您永远不会得到它。

【参考方案3】：

尽管这是一个非常古老的问题，但我刚从谷歌来到这里，是的，每个人都通过复制其他人的答案来回答这不是很有趣吗？

因此，对于像我这样来自 google 的所有人，请对拼写错误一笑置之，因为 mite 让您一两分钟都想知道为什么它不起作用。

[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

有效，但是

[[UIApplication sharedApplication] scheduleLocalNotiication:localNotification];

通知不...

它正在工作

        // Override point for customization after application launch.

        [[UIApplication sharedApplication] cancelAllLocalNotifications];

        [componentsForReferenceDate setDay:27];
        [componentsForReferenceDate setMonth:10];
        [componentsForReferenceDate setYear:2016];

        NSDate *referenceDate = [calendar dateFromComponents:componentsForReferenceDate];

        // set components for time 7:00 a.m.

        NSDateComponents *componentsForFireDate = [calendar components:(NSCalendarUnitYear | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond ) fromDate: referenceDate];

        [componentsForFireDate setHour:8];
        [componentsForFireDate setMinute:0];
        [componentsForFireDate setSecond:0];


        NSDate *fireDateOfNotification = [calendar dateFromComponents:componentsForFireDate];

        // Create the notification

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

        notification.fireDate = fireDateOfNotification;
        notification.timeZone = [NSTimeZone localTimeZone];
        notification.alertBody = [NSString stringWithFormat: @"БЛАГОСЛОВИТЕ ПРОРОКА (с.а.в)"];
        notification.repeatInterval= NSCalendarUnitDay;
        notification.soundName = UILocalNotificationDefaultSoundName;
        [[UIApplication sharedApplication] setApplicationIconBadgeNumber: 1];
        [[UIApplication sharedApplication] scheduleLocalNotification:notification];
        [[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];

        return YES;
