ios - POI跟踪越野

Question

我目前正在使用这个 API 的 POI 跟踪功能和轮流导航。我注意到该 API 似乎只检测恰好位于道路上的 POI。

我认为这可能是由于我实例化了 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])

我已阅读这篇文章http://sdkblog.skobbler.com/detecting-tracking-pois-in-your-way/规则的参数:

rule.routeDistance

有一个默认值。我想如果一个POI没有放在路上，那么这个参数就无法实现，因为API找不到从用户位置到POI的任何道路。 我的问题是: 这是否意味着 POI 总是需要放置在道路上？如果是这样，是否可以停用此参数？

感谢所有尝试解决此问题的人。

这是我的完整代码:

Answer 1

这就是您的 SKTrackablePOIRule 的样子:

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

查看文档 ( SKTrackablePOIRule ) 并考虑应满足所有规则。

[编辑:2016 年 3 月 28 日]:在我们添加的演示应用程序中 example with some POIs没有放在路上(另请参阅更新的 POITrackerViewController class )并且一切都按预期工作。
