ios - 使用本地通知 api 在 swift 3 中触发每周通知

Question

我想触发每周一晚上 7:00 发出的每周通知。

我看到这样的代码:

let triggerWeekly = Calendar.current.dateComponents([.weekday, .hour, .minute, .second], from: date)
let trigger = UNCalendarNotificationTrigger(dateMatching: triggerWeekly, repeats: true)

1. 我应该将开始日期设置为什么？
2. 此外，日期是否需要在现在？

我正在使用 iOS 10+ 和 swift 3。

Answer 1

传递要生成本地通知的日期

            let strDate = (data as AnyObject).value(forKey: "not_date") as? String
            let dateformatter = DateFormatter()
            dateformatter.dateFormat = "yyyy-MM-dd hh:mm a"
            let notidate = dateformatter.date(from: strDate!)

需要先stattnotificationdate like = 2018-06-25 07:00 PM 之后需要加上时间间隔

var dateStart = Date() 
dateStart = dateStart.addingTimeInterval(TimeInterval(604800))

并通过这些interwal生成通知

//MARK:- Schedule Notification with Daily bases.
        func scheduleNotification(at date: Date, body: String, titles:String) {
            let triggerDaily = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute, .second], from: date)

            if #available(iOS 10.0, *) {
                let trigger = UNCalendarNotificationTrigger(dateMatching: triggerDaily, repeats: true)
                let content = UNMutableNotificationContent()
                content.title = titles
                content.body = body
                content.sound = UNNotificationSound.default()
                content.categoryIdentifier = "HardikBar"

                let request = UNNotificationRequest(identifier: "NotificationAt-\(date))", content: content, trigger: trigger)
                UNUserNotificationCenter.current().add(request) {(error) in
                    if let error = error {
                        print("Uh oh! We had an error: \(error)")
                    }
                }
            } else {
                // Fallback on earlier versions
            }

        }
