Ios 如何在谷歌地图上绘制正确的多段线
我已经成功地从a点到b点绘制了一条多段线，但由于某些原因，它显示的是线性线，而不是正确的航路点 这是密码Ios 如何在谷歌地图上绘制正确的多段线,ios,swift,google-maps,google-maps-api-3,google-maps-sdk-ios,Ios,Swift,Google Maps,Google Maps Api 3,Google Maps Sdk Ios,我已经成功地从a点到b点绘制了一条多段线，但由于某些原因，它显示的是线性线，而不是正确的航路点 这是密码 let path = GMSMutablePath() path.addLatitude(3.1970044, longitude:101.7389365) path.addLatitude(3.2058354, longitude:101.729536) let polyline = GMSPolyline(path: path)

您需要获得路线的所有积分。要获得路线，您需要使用Google Direction API。然后使用数组的第一个结果，即最短的结果，使用编码路径使用pathFromEncodedPath:method绘制一条多边形线。self.googleMapsView是google地图视图 示例：self.getDirections（“26.9211992,75.8185761”，目的地：“26.8472496,75.7691909”，航路点：[“26.8686811,75.7568383]，旅行模式：无，完成处理程序：无） 示例：谷歌方向链接
