如何在用户通知中设置重复频率 [英] How to set repeat frequency in User Notification

问题描述

直到 iOS 9 我们写本地通知就像这样

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 ，现在在 WWDC2016 Apple宣布用户通知其中包含

and in local notification we have repeatInterval, Now in WWDC2016 Apple announced User Notification which contains

• UNTimeIntervalNotificationTrigger。



• UNCalendarNotificationTrigger。

• UNTimeIntervalNotificationTrigger.

• UNCalendarNotificationTrigger.

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

上面的代码会在每分钟后触发通知。但无法设置日期。

the code above will trigger notification after every minute. But can't set the date.

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。

the code above date can be set and repeat will trigger tomorrow at 8:30 not not after minute.

在iOS 10中用户通知我如何设置重复频率的日期时间，就像我们可以设置 UILocalNotification ？

In iOS 10 User Notification how I can set date time with repeat frequency just like we can set in UILocalNotification?

我想明天在8点安排用户通知 ：下午30点，每分钟后继续重复，就像我在顶部指定的关于本地通知的代码

I want to schedule User Notification tomorrow at 8:30pm and keep repeating after every minute just like the code I specified at the top regarding local notification

推荐答案

受@Ramon Vasconcelos启发，我使用以下代码设置间隔和fireDate

inspired by @Ramon Vasconcelos, I'm using the following code for setting up intervals and fireDate together

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];
