在此处输入图像描述我正在做一个应用程序,即使应用程序未运行,我也希望在其中通知用户某些事情。就像在优步司机应用程序中一样,系统会提醒用户接受/拒绝乘车请求。VoIP 和 PushKit 可以做到这一点吗?最好的方法是什么?

是的,这可以通过 pushkit 静默通知实现。

收到推送工具包有效负载后,您必须安排本地通知。

您可以使本地通知与接受/拒绝乘车请求交互,并在点击事件上做适当的事情,如 API 调用、SQLite 等。

参考下面的代码。我已经根据 VOIP 通话功能起草了这个,您可以根据您的要求起草。

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
                    }

        }
    }

}
