我目前正在通过该API依次使用POI跟踪功能和导航。我已经注意到，API似乎仅检测准确放置在道路上的POI。
我认为这可能是由于我已实例化的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])
我已经在http://sdkblog.skobbler.com/detecting-tracking-pois-in-your-way/上阅读了该规则的参数:
rule.routeDistance
具有默认值。我想如果未在道路上放置POI，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:
这是否意味着始终需要在道路上放置POI？如果是这样，是否可以停用此参数？
感谢任何尝试解决此问题的人。

最佳答案
这是您的SKTrackablePOIRule的外观: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)，并考虑应满足所有所有规则。
[编辑:28-03-2016]:在演示应用程序中，我们添加了example with some POIs和未放置在道路上的POITrackerViewController class(也请查看更新的ojit_a)，一切正常。
