我试图随着对象的移动在Google地图上绘制一条折线,有时发送的坐标可能会重复。我想防止将重复坐标添加到GMSMutablePath中。无论如何要实现?
当前,我使用以下方法将坐标添加到GMSMutablePath中。它也添加重复的值!
self.path.addLatitude(coordinate.latitude, longitude: coordinate.longitude)
最佳答案
在对GoogleMaps SDK
进行一些挖掘之后,我得出了这个解决方案。它可能不是完美的选择,但您可以尝试一下。
您可以使用coordinate(at:index)
的GMSMutablePath
方法遍历路径的所有坐标
迭代GMSMutablePath
坐标。
//Here path is your GMSMutablePath
for i in 0..<path.count() {
let coordinate = path.coordinate(at: i)
//The coordinate received is a CLLocationCoordinate2D type from which you can get the latitude and longitude.
//Here check the coordinate latitude and longitude is same as your received coordinate, make a return else add to your path.
//You can also keep a flag variable and at the end of all iterations, you can check whether the coordinate is present or not.
print(coordinate)
}
关于ios - 添加坐标之前如何检查GMSMutablePath中是否存在坐标,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/45141344/
