POI跟蹤越野

我目前正在使用此API的POI跟蹤功能和導航。我注意到API似乎只能檢測到完全放置在道路上的POI。POI跟蹤越野

我想這可能是因爲我已經實例化的SKTrackableRule：

let rule: SKTrackablePOIRule = SKTrackablePOIRule() 
    rule.aerialDistance = 100 
    poiTracker = SKPOITracker() 
    poiTracker.dataSource = self 
    poiTracker.delegate = self 
    poiTracker.setRule(rule, forPOIType: 0) 
    poiTracker.setRule(rule, forPOIType: kTrackablePOITypeIncident) 
    poiTracker.startPOITrackerWithRadius(kRadius, refreshMargin: kRefreshMargin, forPOITypes: [0])

我看了這篇文章http://sdkblog.skobbler.com/detecting-tracking-pois-in-your-way/對規則的參數：

rule.routeDistance

有默認值。我想如果一個POI沒有放在道路上，那麼這個參數就不能實現，因爲API無法找到從用戶位置到POI的任何道路。我的問題是：這是否意味着POI始終需要放在路上？如果是這種情況，是否可以取消激活該參數？

非常感謝任何會嘗試解決此問題的人。

這是它的外觀您SKTrackablePOIRule：

let rule: SKTrackablePOIRule = SKTrackablePOIRule() rule.aerialDistance = 100 rule.routeDistance = 1500 rule.numberOfTurns = 2  rule.maxGPSAccuracy = 100  rule.minSpeedIgnoreDistanceAfterTurn = 80  rule.maxDistanceAfterTurn = 300 rule.eliminateIfUTurn = YES  rule.playAudioWarning= NO

看看文檔（SKTrackablePOIRule），並採取考慮到所有的規則都應該得到滿足。

[編輯：28-03-2016]：在我們添加的演示應用中，以及未放置在道路上的example with some POIs（也請參閱更新的POITrackerViewController class），並且所有內容都按預期工作。

我試圖改變這些規則，但即使我試圖通過改變這些規則的值來最大化機會，我也無法檢測到不直接在路上的POI。我已經看到，我不是唯一一個面臨這個問題的人http://stackoverflow.com/questions/31749059/skpoitrackermanager-not-working-as-excepted – Deks361
