Ios 设置从日期开始重复本地通知

我想设置从日期开始的重复本地通知。例如：

开始日期：2018年6月25日

今天日期：2018年6月21日

我被困在这里了。以下代码正在运行，但从今天起，而不是从2018年6月25日起，将发出本地通知

请查看我的本地通知功能：

它应该每天重复，但从6月25日开始。 提前感谢

试试这个

let notification = UNMutableNotificationContent()
notification.subtitle = ""
notification.sound = UNNotificationSound.default()


notification.userInfo =  userInfo
notification.title = Title
notification.body = Message

let timeStr = time
let splitTime:[String] = timeStr.components(separatedBy: ":")
var dayComponent = DateComponents()
dayComponent.weekday = day as? Int //[1 to 7 get randomly]
dayComponent.hour = Int(splitTime[0])
dayComponent.minute = Int(splitTime[1])

let notificationTrigger = UNCalendarNotificationTrigger(dateMatching: dayComponent, repeats: true)
let lnMessageId:String = message
let dayRequest = UNNotificationRequest(identifier: lnMessageId , content: notification, trigger: notificationTrigger)
UNUserNotificationCenter.current().add(dayRequest, withCompletionHandler: {(_ error: Error?) -> Void in
if error == nil
{
//print("success")
}
else
{
//print("UNUserNotificationCenter Error : \(String(describing: error?.localizedDescription))")
}
})

如果要在设备中测试通知

假设下次通知于2018年6月25日下午7:00送达， 您将在设备设置中将日期修改为2018年6月25日下午6:59 或者将设备设置中的日期修改为2018年6月25日下午7:01

预定的通知将在该时间到达

这只是一个示例，它将在每个特定的工作日重复通知。如果要重复通知，应设置“任何人”顺序，如每日、每周、每周一等。。否则，应使用唯一id注册特定日期（无序日期）的多个通知

请参阅—

如果您希望每天重复通知，但希望跳过第一次。我认为那是不可能的。还有一个类似的问题

祝你好运

尝试以下代码行：

func scheduleDosageLocalNotification(date: Date) {

    reminder.dosageIdentifier = "Dosage_Day"

    var calendar = Calendar.current
    calendar.timeZone = TimeZone.current

    let notificationContent = UNMutableNotificationContent()
    // Configure Notification Content
    notificationContent.title = "DOSAGE REMINDER"
    notificationContent.body = "Remember to take your TEST tablet dialy."

    // Set Category Identifier
    notificationContent.categoryIdentifier = Notification.Category.First
    var components = calendar.dateComponents([.day,.month,.year,.hour, .minute], from: date!)//calendar.dateComponents([.hour, .minute], from: date)

    components.hour = 08
    components.minute = 00


    let notificationTrigger = UNCalendarNotificationTrigger(dateMatching: components, repeats: true)
   // let notificationTrigger = UNTimeIntervalNotificationTrigger(timeInterval: interval!, repeats: true)

    // Create Notification Request
    let identifier = "Dosage_Day"

    let notificationRequest = UNNotificationRequest(identifier: identifier, content: notificationContent, trigger: notificationTrigger)

    // Add Request to User Notification Center
    UNUserNotificationCenter.current().add(notificationRequest) { (error) in
        if let error = error {
            print("Unable to Add Notification Request (\(error), \(error.localizedDescription))")
        }

        Utilities.saveContextForAppInfo()
    }

}

我变了

var components = calendar.dateComponents([.hour, .minute], from: date)

到

更新答案：

func scheduleDosageLocalNotification(date: Date) {
reminder.dosageIdentifier = "Dosage_Day"
var calendar = Calendar.current
calendar.timeZone = TimeZone.current
let notificationContent = UNMutableNotificationContent()
// Configure Notification Content
notificationContent.title = "DOSAGE REMINDER"
notificationContent.body = "Remember to take your TEST tablet dialy."
// Set Category Identifier
notificationContent.categoryIdentifier = Notification.Category.First
var components = calendar.dateComponents([.day, .month, .year, .hour, .minute], from: date!) //calendar.dateComponents([.hour, .minute], from: date)
components.hour = 08
components.minute = 00
var notification: UILocalNotification = UILocalNotification()
notification.category = "Dosage_Day"
notification.alertBody = "Local notification"
notification.fireDate = newDate
notification.repeatInterval = .day
print(notification)
print(notification.fireDate)
UIApplication.sharedApplication().scheduleLocalNotification(notification)
Utilities.saveContextForAppInfo()

} }

快乐编码…

您在函数中传递的参数是什么-scheduleDosageLocalNotification？日期：2018年6月25日@KeyurTailor@DheerajD你找到解决办法了吗？如果是，你能分享吗？我将如何获得日价值？dayComponent.weekday=日期为？Int@ramjust随机获得1到7之间的值，如果我们得到第1天，每天1个用户都会在预定时间收到通知。感谢您的帮助。。。但我想你还没有明白我的意思@拉米不想跳过任何东西。我只想在n天后开始重复通知。能做到吗？谢谢你的帮助@ram，但我仍然没有得到我所需要的。谢谢你的回答@Payal Maniyar。但它不是每天重复，而是每三天重复一次。你必须发出本地通知。如果你想实施本地通知，请检查更新的答案。这是一种传统方式，不推荐感谢你的帮助@Payal Maniyar，但它仍然不适用于我。

 var components = calendar.dateComponents([.day,.month,.year,.hour, .minute], from: date!)

func scheduleDosageLocalNotification(date: Date) {
reminder.dosageIdentifier = "Dosage_Day"
var calendar = Calendar.current
calendar.timeZone = TimeZone.current
let notificationContent = UNMutableNotificationContent()
// Configure Notification Content
notificationContent.title = "DOSAGE REMINDER"
notificationContent.body = "Remember to take your TEST tablet dialy."
// Set Category Identifier
notificationContent.categoryIdentifier = Notification.Category.First
var components = calendar.dateComponents([.day, .month, .year, .hour, .minute], from: date!) //calendar.dateComponents([.hour, .minute], from: date)
components.hour = 08
components.minute = 00
var notification: UILocalNotification = UILocalNotification()
notification.category = "Dosage_Day"
notification.alertBody = "Local notification"
notification.fireDate = newDate
notification.repeatInterval = .day
print(notification)
print(notification.fireDate)
UIApplication.sharedApplication().scheduleLocalNotification(notification)
Utilities.saveContextForAppInfo()
