請問我有關於如何在特定時間觸發本地通知的問題?無需用戶觸發,並需要在特定的時間應用解僱本地通知在特定時間發起本地通知
下面我的代碼:
這是從用戶那裏得到許可
func registerLocal() {
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
if granted {
print("Yay!")
} else {
print("D'oh")
}
}
}
//這個我安排本地通知 FUNC scheduleLocal(){
let center = UNUserNotificationCenter.current()
let content = UNMutableNotificationContent()
content.title = "Late wake up call"
content.body = "The early bird catches the worm, but the second mouse gets the cheese."
content.categoryIdentifier = "alarm"
content.userInfo = ["customData": "fizzbuzz"]
content.sound = UNNotificationSound.default()
var dateComponents = DateComponents()
dateComponents.hour = 3
dateComponents.minute = 19
dateComponents.day = 3
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
center.add(request)
center.removeAllPendingNotificationRequests()
}
//她我打電話論文方法
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
registerLocal()
scheduleLocal()
return true
}
,當我關閉我的應用我沒有收到通知,請幫助我如何能夠觸發在特定時間本地通知
感謝
