[英]How to get the remaining time of pending UNNotificationRequest?
到目前為止,加入后UNNotificationRequest
到UNUserNotificationCenter
包含UNTimeIntervalNotificationTrigger
(下面是我實現的代碼):
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
if granted {
let content = UNMutableNotificationContent()
center.delegate = self
content.title = "title"
content.body = "body"
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 10.0, repeats: false)
let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
center.add(request)
}
}
它可以正常工作,但我需要的是訪問剩余時間來觸發請求觸發器。
為了清楚起見,在我的代碼段中,我聲明了:
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 10.0, repeats: false)
因此,如果我等待6秒(從執行上述代碼段開始),則剩余時間應為4秒。
另外,我嘗試獲取待處理的請求以檢查其觸發器,如下所示:
UNUserNotificationCenter.current().getPendingNotificationRequests(completionHandler: { requests in
for request in requests {
print(request.trigger)
}
})
但在UNNotificationTrigger中找不到所需的屬性。
問題可能是什至有一種訪問方法? 如果不是,那么實現該目標的邏輯解決方法呢?
我從待處理的UNNotificationRequest Swift4代碼中獲取時間間隔值
UNUserNotificationCenter.current().getPendingNotificationRequests(completionHandler: {requests -> () in
for request in requests {
let localTrigger = request.trigger as! UNTimeIntervalNotificationTrigger
localTimeInterval = localTrigger.timeInterval
print (localTimeInterval)
}})
