如何在用户通知中设置重复频率[重复]

这个问题在这里已有答案：

直到 iOS 9 我们这样写 local notifications

UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = pickerDate;
localNotification.alertBody = self.textField.text;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.repeatInterval = NSCalendarUnitMinute;
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

在本地通知中我们有 repeatInterval ，现在 WWDC2016 Apple宣布 User Notification 其中包含

  • UNTimeIntervalNotificationTrigger .

  • UNCalendarNotificationTrigger .

UNTimeIntervalNotificationTrigger* trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:60 repeats:YES];

上面的代码会在每分钟后触发通知 . 但无法设定日期 .

NSDateComponents* date = [[NSDateComponents alloc] init];
date.hour = 8;
date.minute = 30;

UNCalendarNotificationTrigger* triggerC = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:date repeats:YES];

上面的代码可以设置，重复将在明天8:30触发，而不是在分钟后 .

在iOS 10 User Notification 中如何设置重复频率的日期时间，就像我们可以在_900113中设置一样？

我想明天晚上8:30安排 User Notification 并在每分钟后继续重复，就像我在顶部指定的代码 local notification

ios objective-c nsdate uilocalnotification nsdatecomponents

    对于iOS 10，您可以这样使用：

    NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond fromDate:fireDate];
UNCalendarNotificationTrigger* trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:YES];

    它与iOS 9代码具有相同的效果 . 要重复，您只需使用要重复的组件即可 .

    受@Ramon Vasconcelos的启发，我使用以下代码一起设置间隔和fireDate

    switch (interval) {
    case NSCalendarUnitMinute: {
        unitFlags = NSCalendarUnitSecond;
        break;
    }
    case NSCalendarUnitHour: {
        unitFlags = NSCalendarUnitMinute | NSCalendarUnitSecond;
        break;
    }
    case NSCalendarUnitDay: {
        unitFlags = NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond;
        break;
    }
    case NSCalendarUnitWeekOfYear: {
        unitFlags = NSCalendarUnitWeekday | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond;
        break;
    }
    case NSCalendarUnitMonth:{
        unitFlags = NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond;
    }
    case NSCalendarUnitYear:{
        unitFlags = NSCalendarUnitMonth | NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond;
    }
    default:
        unitFlags = NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear | NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond;
        break;
}
NSDateComponents *components = [[NSCalendar currentCalendar] components:unitFlags fromDate:fireDate];
UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:interval != 0];
