设置了 repeatInterval 的 UILocalNotification NSWeekdayCalendarUnit 不会每周触发

Question

我正在尝试将本地通知设置为每周重复一次。
这是我的设置：

UILocalNotification* localNotification =  [[UILocalNotification alloc] init];
...
localNotification.repeatInterval = NSWeekdayCalendarUnit;

在控制台日志中：

localNotif: {fire date = Friday, April 24, 2015 at 12:27:33 PM Singapore Standard Time, time zone = Asia/Singapore (GMT+8) offset 28800, repeat interval = NSWeekdayCalendarUnit, repeat count = UILocalNotificationInfiniteRepeatCount, next fire date = Saturday, April 25, 2015 at 12:27:33 PM Singapore Standard Time, user info = { KUserLocalNotficationKey = "2015-04-24 04:27:33 +0000"; }}

如您所见，下一个触发日期是在第二天触发的。这是一个错误吗？
我已经在 iOS 7.1、8.1、8.3 中对其进行了测试。

Answer 1

你必须这样编码

UILocalNotification* localNotification =  [[UILocalNotification alloc] init];
...
localNotification.repeatInterval = NSCalendarUnitWeekOfYear;

它每周触发一次通知。

Answer 2

PLz 试试这个

  UILocalNotification *localNotif=[[UILocalNotification alloc]init];
        localNotif.fireDate =currentDate;
        localNotif.timeZone=[NSTimeZone defaultTimeZone];
        localNotif.alertBody = @"MazeRoll";
        localNotif.soundName = UILocalNotificationDefaultSoundName;
        localNotif.applicationIconBadgeNumber = 1;
        localNotif.repeatInterval=NSWeekCalendarUnit;
        UIApplication *app=[UIApplication sharedApplication];
        [app scheduleLocalNotification:localNotif];
        NSLog(@"sdfsdfsdf%@",[[UIApplication sharedApplication] scheduledLocalNotifications]);

Answer 3

您可以使用 NSCalendarUnitWeekOfYear 设置本地通知并设置适当的触发日期。

UILocalNotification *localNotification=[[UILocalNotification alloc]init];
localNotification.fireDate =[NSDate date]; // set your week day on which repeatedly you want local notfication. for example Monday, then set Fire date of next monday.
localNotification.timeZone=[NSTimeZone defaultTimeZone];
localNotification.repeatInterval=NSCalendarUnitWeekOfYear;
NSLog(@"%@",localNotification);

希望这对您有所帮助。享受编码!!

Answer 4

 NSDate *currentDate = [NSDate date];
    NSDate *futureTime = [currentDate dateByAddingTimeInterval:60*60*168];
    NSCalendar *calendar = [NSCalendar currentCalendar];
    NSTimeZone *timeZone = [NSTimeZone systemTimeZone];
    [calendar setTimeZone:timeZone];
    NSDateComponents *components = [calendar components:NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit fromDate:futureTime];
    if ([components hour] >= 19) { // make it the next day
        [components setDay:[components day] + 1 ];
    }
    [components setHour:8];
    [components setMinute:00];
    NSDate *alertTime = [calendar dateFromComponents:components];
    NSLog(@"alertTime %@",alertTime.description);
    UILocalNotification *localNotif=[[UILocalNotification alloc]init];
    localNotif.fireDate =alertTime;
    localNotif.timeZone=[NSTimeZone defaultTimeZone];
    localNotif.alertBody = @"MazeRoll";
    localNotif.soundName = UILocalNotificationDefaultSoundName;
    localNotif.applicationIconBadgeNumber = 1;
    localNotif.repeatInterval=NSDayCalendarUnit;
    UIApplication *app=[UIApplication sharedApplication];
    [app scheduleLocalNotification:localNotif];
    NSLog(@"sdfsdfsdf%@",[[UIApplication sharedApplication] scheduledLocalNotifications]);

设置了 repeatInterval 的 UILocalNotification NSWeekdayCalendarUnit 不会每周触发

UILocalNotification with repeatInterval set NSWeekdayCalendarUnit doesn't trigger weekly
