[英]How to repeat local notifications on specific days of the week (iOS Swift 3)
[英]Repeating local notifications for specific days of week (Swift 3 IOS 10)
我正在尝试安排一周中特定日期的本地通知(例如周一,周三等),然后每周重复一次。 这是用于设置通知的屏幕的外观:
用户可以选择通知时间和重复日期。
我调度单个非重复通知的方法如下所示:
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:
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:
//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,.hour,.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", content: content, 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)")
}
}
}
正从选择器通选择器的小时,分钟和年份的值与选定的一周一天(星期日= 1,星期一= 2,周二= 3,周三= 4,星期四= 5,周五= 6,星期六= 7)功能后, func createDate(weekday: Int, hour: Int, minute: Int, year: Int)
获取每周基础上的通知开火日期,并在获取日期调用函数func scheduleNotification(at date: Date, body: String, titles:String)
安排通知。
let content = UNMutableNotificationContent()
content.title = NSString.localizedUserNotificationString(forKey: "Wake up!", arguments: nil)
content.body = NSString.localizedUserNotificationString(forKey: "Rise and shine! It's morning time!",
arguments: nil)
content.categoryIdentifier = "TIMER_EXPIRED"
let weekdaySet = [6,5]
for i in weekdaySet {
var dateInfo = DateComponents()
dateInfo.hour = 16
dateInfo.minute = 44
dateInfo.weekday = i
dateInfo.timeZone = .current
let trigger = UNCalendarNotificationTrigger(dateMatching: dateInfo, repeats: true)
let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
center.add(request) { (error : Error?) in
if let theError = error {
print(theError.localizedDescription)
}
}
}
