工作日本地通知未触发

【中文标题】工作日本地通知未触发

【英文标题】：Weekday Local Notification Not Firing

【发布时间】：2015-03-02 23:30:46

【问题描述】：

我正在构建一个应用程序，允许用户在每个工作日重复本地通知，因为苹果没有 WeekDays 的重复间隔，我需要为每个工作日创建本地通知。我做了一个 for 循环循环 5 次工作周中的天数。然而，它似乎并没有被解雇。但是，当我要删除所有五个通知时，就不会触发。这就是我的代码的样子。

NSDate *today = [NSDate date];
UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = _alarmTime;
localNotification.alertBody = @"Wake up or pay-up!";
localNotification.timeZone = [NSTimeZone systemTimeZone];
localNotification.alertAction = @"Wake up or pay-up!";
localNotification.soundName = @"sound_ring.caf";

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

switch (_repeatInt) 
    case 1:
        localNotification.repeatInterval = NSCalendarUnitDay;
        [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
        _repeatString = @"Everyday";
        break;

    case 2:
        //Attempting to create 5 local notifications with different days but same time.
        for (int i = 2; i <= 6; i++)

            [dateComponent setWeekday:i]; // 2 = mon // 3= tues // 4 = wends // 5 = thurs // 6 = fri
            NSDate *fireDate = [gregCalendar dateFromComponents:dateComponent];

            UILocalNotification *localNotification2 = [localNotification copy];
            localNotification2.fireDate = fireDate;
            localNotification2.repeatInterval = NSWeekCalendarUnit;
            [[UIApplication sharedApplication] scheduleLocalNotification:localNotification2];
            NSLog(@"%D",i);

        

如果有人有任何想法，请告诉我！提前致谢。

更新：

NSDate *startDate = [gregCalendar dateFromComponents:dateComponent];
            [dateComponent setMonth:0];
            [dateComponent setDay:i]; // 2 = mon // 3= tues // 4 = wends // 5 = thurs // 6 = fri
            [dateComponent setYear:0];

            NSDate *fireDate = [gregCalendar dateByAddingComponents:dateComponent toDate:startDate options:0];

            UILocalNotification *localNotification2 = [localNotification copy];
            localNotification2.fireDate = fireDate;
            localNotification2.repeatInterval = NSCalendarUnitWeekOfYear;
            [[UIApplication sharedApplication] scheduleLocalNotification:localNotification2];
            NSLog(@"%D",i);

【问题讨论】：

但是...您在 AppDelegate 中有...注册发送通知的代码吗？

@TonyMkenu 是的，我已经有了。

@jack 在您的代码中声明“_repeatInt”的位置。请让我知道它需要。

【参考方案1】：

好的，我终于能够在每个工作日重复接收本地通知，我添加了 [setHour] 和 [setMinute] 并将 for 循环中的 int 更改为 NSUInteger。下面是我的代码。

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

switch (_repeatInt) 
    case 1:
        localNotification.repeatInterval = NSCalendarUnitDay;
        [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
        _repeatString = @"Everyday";
        break;

    case 2:

        for (NSUInteger i = 2; i <= 6; i++) 

            NSDateComponents *components = [gregCalendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:_alarmTime];
            NSInteger hour = [components hour];
            NSInteger minute = [components minute];

            [dateComponent setMinute:minute];
            [dateComponent setWeekday:i]; // 2 = mon // 3= tues // 4 = wends // 5 = thurs // 6 = fri
            [dateComponent setHour:hour];

            NSDate *fireDate = [gregCalendar dateFromComponents:dateComponent];

            UILocalNotification *localNotification2 = [[UILocalNotification alloc] init];
            localNotification2.fireDate = fireDate;
            localNotification2.alertBody = @"Wake up or pay-up!";
            localNotification2.timeZone = [NSTimeZone systemTimeZone];
            localNotification2.alertAction = @"Wake up or pay-up!";
            localNotification2.soundName = @"sound_ring.caf";
            localNotification2.repeatInterval = NSCalendarUnitWeekOfYear;
            [[UIApplication sharedApplication] scheduleLocalNotification:localNotification2];
            NSLog(@"%lu",(unsigned long)i);

        

【参考方案2】：

它们不会触发，因为您给它们的日期无效。

以下是我如何生成未来 X 天的日期：

        NSCalendar *calendar = [NSCalendar currentCalendar];
        NSDateComponents *components = [calendar components:(NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay) fromDate:[NSDate date]];
        NSDate *startDate = [calendar dateFromComponents:components];
        [components setMonth:0];
        [components setDay:X];
        [components setYear:0];
        NSDate *endDate = [calendar dateByAddingComponents:components toDate:startDate options:0];
