Question

我是iOS编程的新手，在我的应用程序中，我有一个必须在某个时间出现的UILocaleNotification。

首先我设置参数：

let notificationSettings: UIUserNotificationSettings! = UIApplication.sharedApplication().currentUserNotificationSettings()

    if (notificationSettings.types == UIUserNotificationType.None) {
        var notificationTypes: UIUserNotificationType = UIUserNotificationType.Alert | UIUserNotificationType.Sound

        // Bouton d'envoi
        var sendAction = UIMutableUserNotificationAction()
        sendAction.identifier = "send"
        sendAction.title = "Send"
        sendAction.activationMode = UIUserNotificationActivationMode.Foreground
        sendAction.destructive = false
        sendAction.authenticationRequired = true

        // Bouton de non-envoi
        var dontSendAction = UIMutableUserNotificationAction()
        dontSendAction.identifier = "dontsend"
        dontSendAction.title = "Don't send"
        dontSendAction.activationMode = UIUserNotificationActivationMode.Background
        dontSendAction.destructive = true
        dontSendAction.authenticationRequired = false

        let actionsArray = NSArray(objects: sendAction, dontSendAction)

        var reminderNotification = UIMutableUserNotificationCategory()
        reminderNotification.identifier = "reminderNotification"
        reminderNotification.setActions(actionsArray as [AnyObject], forContext: UIUserNotificationActionContext.Minimal)

        let categoriesForSettings = NSSet(objects: reminderNotification)

        let newNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: categoriesForSettings as Set<NSObject>)
        UIApplication.sharedApplication().registerUserNotificationSettings(newNotificationSettings)
    }

...我按照这样安排通知：

var localNotification = UILocalNotification()
    localNotification.fireDate = NSDate(timeIntervalSinceNow: 3)
    localNotification.timeZone = NSTimeZone.defaultTimeZone()
    localNotification.alertBody = "Hey, inform your contacts !"
    localNotification.alertAction = "Send Message"
    localNotification.category = "reminderNotification"
    localNotification.soundName = UILocalNotificationDefaultSoundName

    UIApplication.sharedApplication().scheduleLocalNotification(localNotification)

当我尝试此代码时，通知显示在通知中心，但没有弹出显示... 我在网上搜索来源，我不明白为什么这些例子和tutos显示弹出窗口，因为我写了相同的代码......

感谢您的帮助，祝您度过愉快的一天！

编辑：我忘记了一些事情：通知中心必须检测事件，而不是区域设置通知。所以我希望通知中心的addObserver检查事件，是否可能处于后台状态？

根据此行：<parameter name="transport.vfs.FileURI">file:///home/user/test/in</parameter>  <parameter name="transport.vfs.ContentType">text/xml</parameter> <parameter name="transport.vfs.FileNamePattern">.*\.xml</parameter> <parameter name="transport.PollInterval">15</parameter> <parameter name="transport.vfs.MoveAfterProcess">file:///home/user/test/original</parameter>  <parameter name="transport.vfs.MoveAfterFailure">file:///home/user/test/original</parameter>  <parameter name="transport.vfs.ActionAfterProcess">MOVE</parameter> <parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter> <target> <endpoint> <address format="soap12" uri="http://localhost:9000/services/SimpleStockQuoteService"/> </endpoint> <outSequence> <property name="transport.vfs.ReplyFileName" expression="fn:concat(fn:substring-after(get-property('MessageID'), 'urn:uuid:'), '.xml')" scope="transport"/> <property action="set" name="OUT_ONLY" value="true"/> <send> <endpoint> <address uri="vfs:file:///home/user/test/out"/>  </endpoint> </send> </outSequence> </target> <publishWSDL uri="file:repository/samples/resources/proxy/sample_proxy_1.wsdl"/> </proxy>您希望在3秒后触发通知。我认为应用程序在发生时仍处于前台。如果是这样，您将不会有通知弹出窗口。

如果在收到通知时打开了与通知关联的应用，则必须在localNotification.fireDate = NSDate(timeIntervalSinceNow: 3)中处理该应用以显示自定义弹出窗口。

AppDelegate

不会显示iOS区域设置通知弹出窗口
