ios - 即使应用未运行也显示警报

我正在做一个应用程序，即使该应用程序未运行，我也希望在其中通知用户。就像在uber driver应用中一样，系统会提醒用户接受/拒绝乘车请求。 VoIP和PushKit是否可能？哪种方法最好？

最佳答案

是的，这可以通过Pushkit静默通知来实现。

收到推包有效载荷后，您必须安排本地通知。

您可以使本地通知与接受/拒绝乘车请求进行交互，并在点击事件中执行适当的操作，例如API调用，SQLite等。

请参考以下代码。 我已经根据VOIP call 功能起草了此文件，您可以根据需要起草。

func pushRegistry(registry: PKPushRegistry!, didReceiveIncomingPushWithPayload payload: PKPushPayload!, forType type: String!) {
        // Process the received push

        var arrTemp = [NSObject : AnyObject]()
        arrTemp = payload.dictionaryPayload

        let dict : Dictionary <String, AnyObject> = arrTemp["aps"] as! Dictionary<String, AnyObject>


        if "IfUserHasLoggedInWithApp" // Check this flag then only proceed
        {

            if UIApplication.sharedApplication().applicationState == UIApplicationState.Background || UIApplication.sharedApplication().applicationState == UIApplicationState.Inactive
            {

                if "CheckForIncomingCall" // Check this flag to know incoming call or something else
                {

                    var strTitle : String = dict["alertTitle"] as? String ?? ""
                    let strBody : String = dict["alertBody"] as? String ?? ""
                    strTitle = strTitle + "\n" + strBody

                    let notificationIncomingCall = UILocalNotification()

                    notificationIncomingCall.fireDate = NSDate(timeIntervalSinceNow: 1)
                    notificationIncomingCall.alertBody =  strTitle
                    notificationIncomingCall.alertAction = "Open"
                    notificationIncomingCall.soundName = "SoundFile.mp3"
                    notificationIncomingCall.category = dict["category"] as? String ?? ""

                    notificationIncomingCall.userInfo = "As per payload you receive"

                    UIApplication.sharedApplication().scheduleLocalNotification(notificationIncomingCall)

                    }
                    else
                    {
                        //  something else
                    }

        }
    }

}
