如何在 flutter:
assets:
- icons/heart.png
的{{1}}中添加插图以与boundingMapRect
一起使用?
MKPolyline
答案 0 :(得分:0)
您可以像这样向该区域添加跨度:
// This will add a 10% increase in the span.
var region = MKCoordinateRegion(polyLine.boundingMapRect)
region.span.latitudeDelta = 1.1
region.span.longitudeDelta = 1.1
编辑:
这也是一种选择:
let region = polyLine.boundingMapRect
map.setVisibleMapRect(region, edgePadding: UIEdgeInsets(top: 50.0, left: 50.0, bottom: 50.0, right: 50.0), animated: true)
