我正在尝试为一周中的特定日期(例如星期一,星期三等)安排本地通知,然后每周重复一次.
这是用于设置通知的屏幕的外观： @H_404_8@static func scheduleNotification(reminder: Reminder) { // Setup notification content. let content = UNMutableNotificationContent() //content.title = NSString.localizedUserNotificationString(forKey: "Reminder",arguments: nil) content.body = NSString.localizedUserNotificationString(forKey: reminder.reminderMessage,arguments: nil) content.sound = UNNotificationSound.default() // Configure the triger for specified time. // let dateComponentes = reminder.dateComponents // TODO: Configure repeating alarm // For the testing purposes we will not repeat the reminder let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponentes,repeats: false) // Create the request object. let request = UNNotificationRequest(identifier: "\(reminder.reminderId)",content: content,trigger: trigger) // Schedule the request. let notificationCenter = UNUserNotificationCenter.current() notificationCenter.add(request) { (error: Error?) in if let theError = error { print(theError.localizedDescription) } } }

日期组件从UIDatePicker小部件中提取并存储在提醒类中：
@H_404_8@let date = reminderTimeDatePicker.date.addingTimeInterval(60 * 60 * 24 * 7) let components = Calendar.current.dateComponents([.weekday,.hour,.minute],from: date) ... reminder.dateComponents = components我有一个数组selectedDays [Int](作为提醒类的属性)来保存通知应该触发的星期几的信息.
如何在一周中的特定日期安排通知以及如何每周重复一次？
即使是一条评论也会有所帮助,并提前感谢您.
您可以使用以下函数从所选的选择器值中获取日期：
@H_404_8@//Create Date from picker selected value.
func createDate(weekday: Int,hour: Int,minute: Int,year: Int)->Date{
var components = DateComponents()
components.hour = hour
components.minute = minute
components.year = year
components.weekday = weekday // sunday = 1 ... saturday = 7
components.weekdayOrdinal = 10
components.timeZone = .current
let calendar = Calendar(identifier: .gregorian)
return calendar.date(from: components)!
}
//Schedule Notification with weekly bases.
func scheduleNotification(at date: Date,body: String,titles:String) {
let triggerWeekly = Calendar.current.dateComponents([.weekday,.minute,.second,],from: date)
let trigger = UNCalendarNotificationTrigger(dateMatching: triggerWeekly,repeats: true)
let content = UNMutableNotificationContent()
content.title = titles
content.body = body
content.sound = UNNotificationSound.default()
content.categoryIdentifier = "todoList"
let request = UNNotificationRequest(identifier: "textNotification",trigger: trigger)
UNUserNotificationCenter.current().delegate = self
//UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
UNUserNotificationCenter.current().add(request) {(error) in
if let error = error {
print("Uh oh! We had an error: \(error)")
}
}
}
从选择器传递选择器小时,分钟和年份中获取值,选定的工作日为(星期日= 1,星期一= 2,星期二= 3,星期三= 4,星期四= 5,星期五= 6,星期六= 7) createDate(工作日：Int,小时：Int,分钟：Int,年份：Int)在每周基础上获取通知开火日期,并在获取日期调用函数func scheduleNotification(日期：日期,正文：字符串,标题：字符串)之后安排通知.
