ios - 没有互联网 iOS swift 无法接收本地通知

Question

我正在使用以下代码在收到远程通知时安排本地通知，

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)
}

成功安排本地通知后。现在，我关闭了互联网，我没有收到本地通知..

有人遇到同样的问题吗？还是我错过了什么？

对于本地通知，在您的 appDelegate 的 didFinishLaunchingWithOptions 中编写此代码:-

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

//并在 Controller 中安排通知:-

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