POI跟踪越野

标签： ios skmaps

我目前正在使用此API的POI跟踪功能和导航。我注意到API似乎只能检测到准确放置在道路上的POI。

我认为这可能是由于我已经实现的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])

我已在本文http://sdkblog.skobbler.com/detecting-tracking-pois-in-your-way/上读到规则的参数：

rule.routeDistance

有一个默认值。我想如果POI没有放在道路上，则无法实现此参数，因为API无法找到从用户位置到POI的任何道路。 我的问题是： 这是否意味着POI总是需要放在路上？如果是这种情况，是否可以取消激活此参数？

感谢任何试图解决此问题的人。

这是我的完整代码：

答案 0 :(得分：1)

这就是你的SKTrackablePOIRule的样子：

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

查看文档（SKTrackablePOIRule）并考虑所有规则都应该完成。

[编辑：28-03-2016]：在演示应用中，我们添加了example with some POIs并且没有放在路上（另请查看更新的POITrackerViewController class）和所有内容按预期工作。
