Question

我正在构建一个应用程序，允许用户在每个工作日都有本地通知重复，因为Apple没有周末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次工作周的天数。然而，它似乎并没有被解雇。但当我删除通知时，我看到所有五个，只是不会开火。这就是我的代码。

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);

        }

如果有任何想法请告诉我！提前谢谢。

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);

好的，我终于能够在每个工作日收到本地通知，我添加了[setHour]和[setMinute]，并将for循环中的int更改为NSInteger。以下是我的代码。

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);

        }

他们不会开火，因为您提供的日期无效。

以下是我将来如何生成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];
