[英]swift display local notification even the app terminated
你好,我想發送日常提醒之類的通知,即使應用終止也無法在后台運行,我該怎么做,這是我的代碼
func soundNotification(){
let prayers = ["fajer","dohor","asr","maghreb","isha"]
let content = UNMutableNotificationContent()
content.title = "\(prayers[indexOfNextPrayer + 1]) azan will be after 5 minutes"
content.badge = 1
content.sound = UNNotificationSound(named: "salah.mp3")
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
let request = UNNotificationRequest(identifier: "azanSoon", content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}
func soundNotification(){
let prayers = ["fajer","dohor","asr","maghreb","isha"]
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
let content = UNMutableNotificationContent()
content.title = "\(prayers[indexOfNextPrayer + 1]) azan will be after 5 minutes"
content.body = " "
content.badge = 1
content.sound = UNNotificationSound(named: "salah.mp3")
let request = UNNotificationRequest(identifier: "azanSoon", content: content, trigger: trigger)
UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
UNUserNotificationCenter.current().add(request) {(error) in
if let error = error {
print("error: \(error)")
}
}
}
在日期和時間觸發本地通知。
func scheduleNotification(at date: Date, message:String) {
let calendar = Calendar(identifier: .gregorian)
let components = calendar.dateComponents(in: .current, from: date)
let newComponents = DateComponents(calendar: calendar, timeZone: .current, month: components.month, day: components.day, hour: components.hour, minute: components.minute)
let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: false)
let content = UNMutableNotificationContent()
content.title = "Reminder"
content.body = message
content.sound = UNNotificationSound.default()
let request = UNNotificationRequest(identifier: "textNotification", content: content, trigger: trigger)
UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
UNUserNotificationCenter.current().add(request) {(error) in
if let error = error {
print("error: \(error)")
}
}
}
