iOS 10通知触发并每分钟重复一次

我想在2分钟内触发通知，从现在开始，我还想每分钟重复一次。以下代码的问题是，它将每分钟重复一次，但会立即启动，而不是在2分钟内。谢谢你的帮助

UNMutableNotificationContent *content = [UNMutableNotificationContent new];
content.title = @"Good morning";
content.body = @"Body";
content.sound = [UNNotificationSound defaultSound];

UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];

NSDate *date = [NSDate dateWithTimeIntervalSinceNow:120];
NSDateComponents *triggerDate = [[NSCalendar currentCalendar]
                                 components:NSCalendarUnitSecond fromDate:date];

UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:triggerDate repeats:YES];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"notification.daily" content:content trigger:trigger];

[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
    NSLog(@"Error:%@", error);
}];

为什么不使用

UNTimeIntervalNotificationTrigger

而不是

uncalendaNotificationTrigger

UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:120 repeats:YES];

希望这个答案会有帮助。

当您收到远程推送通知时，可以每2分钟重复一次

使用下面的方法来做这件事

 func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        let action = response.actionIdentifier
        let request = response.notification.request
        let content = request.content
        if action == "snooze.action"{
            let snoozeTrigger = UNTimeIntervalNotificationTrigger(
                timeInterval: 120.0,
                repeats: true)
            let snoozeRequest = UNNotificationRequest(
                identifier: "snooze",
                content: content,
                trigger: snoozeTrigger)
            center.add(snoozeRequest){
                (error) in
                if error != nil {
                    print("Snooze Request Error: \(String(describing: error?.localizedDescription))")
                }
            }
        }
        completionHandler()
    }

这将在2分钟后开始，但不会在之后的每分钟重复。
