Question

我正在开发一个iOS应用，我需要在地图上向用户显示一些位置。为此，我正在使用谷歌地图。而且真的很好用

信息：在我的应用中，我将视图控制器分为两半。上面的区域显示地图，下面的区域显示UITableView，其中包含从数据库填充的位置。

我到目前为止所做的事情：现在，我从数据库中保存的位置填充列表和google地图。假设我有30个不同的位置，并且通过在地图上放置每个标记并将该标记添加到UItable中来显示地图上的所有位置。每个单元格都包含位置名称和用于从数据库中删除位置的删除按钮

我想要的：

现在我要的是用户可以点击单元格中的删除按钮删除标记。我真的想从地图上删除该标记也是实时的。但是我不知道该怎么做。请帮助

其中

func removeMarkers(mapView: GMSMapView){
    for (index, _) in markers.enumerate() {
        //print("Item \(index): \(element)")
                    self.markers[index].map = nil
    }
}

标记包含mapView的所有标记叠加层

OR

var标记= GMSMarker 标记包含mapView的所有标记叠加层

点击删除

var markers = [GMSMarker]()

从Google Map Swift 4删除标记
