请问我有关于如何在特定时间触发本地通知的问题?无需用户触发,并需要在特定的时间应用解雇本地通知在特定时间发起本地通知
下面我的代码:
这是从用户那里得到许可
func registerLocal() {
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
if granted {
print("Yay!")
} else {
print("D'oh")
}
}
}
//这个我安排本地通知 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()
}
//她我打电话论文方法
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
registerLocal()
scheduleLocal()
return true
}
,当我关闭我的应用我没有收到通知,请帮助我如何能够触发在特定时间本地通知
