昨天用好大部分東西了，今天來增加推播吧。

Notifications

首先要import推播。

import UserNotifications

然後就是開始設定推播裡的內容。

     func createNotificationId(selectRow: Int) {
        let realm = try! Realm()
        let cells = realm.objects(AlarmRealm.self)

        if cells.count > 0 {
            self.notificationID = cells[selectRow].ID
        }
    }
    
    func createNotification(selectRow: Int, repeatDay: Int, weekDay: Bool = false) {
        let realm = try! Realm()
        let cells = realm.objects(AlarmRealm.self)
        let content = UNMutableNotificationContent()
        
        content.title = "Clcok"
        content.body = cells[selectRow].labelText
        content.badge = 0
        content.sound = UNNotificationSound.default
        
        let date = Date()
        let components: Set<Calendar.Component> = weekDay ? ([.weekday, .hour, .minute]) : ([.hour, .minute])
        var dataComponets = Calendar.current.dateComponents(components, from: date)
        
        if weekDay {
            dataComponets.weekday = repeatDay
            dataComponets.hour = cells[selectRow].Hour
            dataComponets.minute = cells[selectRow].Minute
        } else {
            dataComponets.hour = cells[selectRow].Hour
            dataComponets.minute = cells[selectRow].Minute
        }
        
        let trigger = UNCalendarNotificationTrigger(dateMatching: dataComponets, repeats: true)
        let request = UNNotificationRequest(identifier: cells[selectRow].ID, content: content, trigger: trigger)
        
        UNUserNotificationCenter.current().add(request) { (error) in
            if (error != nil) {
                print("錯誤！")
            }
        }
    }

那麼今天就到這裡，明天來完善整個鬧鐘APP。
