Iphone “本地通知”；每天早上7:00”；不通知

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屏。这是我到目前为止所有的代码

-(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];
}

你需要打电话

[[UIApplication sharedApplication] scheduleLocalNotiication:localNotification];

在发布

localNotification

之前。您的代码完成了所有的设置，但实际上并没有安排它，这就是为什么您永远无法获得它。

您需要调用

[[UIApplication sharedApplication] scheduleLocalNotiication:localNotification];

在发布

localNotification

之前。你的代码完成了所有的设置，但实际上并没有对其进行计划，这就是为什么你永远无法得到它。

尝试使用以下方法：

- (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];

}  

如果这有帮助的话，竖起大拇指D

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，每个人的答案都是抄袭别人的答案，这不是很有趣吗

所以，对于所有像我这样来自谷歌的人来说，请笑一笑这个拼写错误，它让你花了一两分钟的时间去思考为什么它不起作用

[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

有效，但是

[[UIApplication sharedApplication] scheduleLocalNotiication:localNotification];

通知不起作用。

它起作用了 它起作用了

什么是Components ForReferenceDate？好吧，让我们假设你在11月份调用了firedate，其他人也会调用firedate，我已经为你设置了代码，做你想做的事情好吧，现在只需将整个代码复制并粘贴到你的应用程序代理中，所以我不必担心Components ForReferenceDate？只需设置NSDay压延机至NSMinute压延机，然后它会在你设置的每分每秒弹出什么是组件被引用？好吧，让我们假设你为setMonth设置tipe:11意味着在11月调用firedate，其他人也一样，我已经为你设置了代码，就是做你想要的事情好吧，现在只需将整个代码复制并粘贴到你的应用程序中，所以我不应该担心引用的组件吗？只需将NSDaycalenderunit设置为NSMinuteCalenderunit，它就会在您设置的每分每秒弹出一次
