沒有互聯網iOS swift無法接收本地通知

Question

我正在通過使用以下代碼收到遠程通知的時刻安排本地通知，

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {

    let scheduleLocalNotification = UILocalNotification()
    scheduleLocalNotification.fireDate = dateFromRemoteNotification
    scheduleLocalNotification.timeZone = NSTimeZone.localTimeZone()
    scheduleLocalNotification.alertBody = "Hi There!"
    scheduleLocalNotification.userInfo = userInfo
    UIApplication.sharedApplication().scheduleLocalNotification(scheduleLocalNotification)
    completionHandler(.NewData)
}

成功調度本地通知后。 現在，我關閉了互聯網，我沒有收到本地通知..

有沒有人面臨同樣的問題？ 還是我錯過了什么？

Answer 1

對於本地通知，請在appDelegate的didFinishLaunchingWithOptions中寫下此代碼： -

let notifyTypes:UIUserNotificationType = [.Alert, .Badge, .Sound]
let settings = UIUserNotificationSettings(forTypes: notifyTypes, categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)

//並在您的控制器中安排通知： -

let notification:UILocalNotification = UILocalNotification()
notification.alertTitle = " "
notification.alertBody = ""
notification.fireDate = NSDate()               
UIApplication.sharedApplication().scheduleLocalNotification(notification)

Answer 2

您正在調用推送通知接收功能。 你必須只調用didReceiveNotification。

並且需要安排來自您的控制器的本地通知而不是此功能。

希望這會幫助你。

Answer 3

您必須在viewWillAppear或按鈕單擊事件上設置此代碼。

不在didReceiveRemoteNotification或didReceiveLocalNotification上。

在viewwillAppear或按鈕上嘗試此代碼

let notification = UILocalNotification()
notification.alertBody = "Local notification text body"
notification.alertAction = "open"
notification.fireDate = NSDate(timeIntervalSinceNow: 1) // this will fire local notification just after 1 second
notification.soundName = "soundName.mp3"
UIApplication.sharedApplication().scheduleLocalNotification(notification)

現在一旦你收到本地通知，當你點擊它時，didReceiveLocalNotification方法將在AppDelegate中調用

如果您想立即觸發本地通知（無需安排），那么您需要以下代碼：

let locNot:UILocalNotification = UILocalNotification();
locNot.alertBody = "Here is the local notification";
UIApplication.sharedApplication().presentLocalNotificationNow(locNot);
