ios - 特定缩放取决于注释

Question

我正在编写 Swift 应用程序，并使用 SDK Skobbler。我想知道是否可以根据注释指示特定的缩放。我想要一个准确的变焦...我知道路由服务有自动缩放的功能:

routingService.zoomToRouteWithInsets(UIEdgeInsetsZero)

这是应用截图:

Answer 1

试试下面的代码

let boundingBox = SKBoundingBox(topLeftCoordinate: CLLocationCoordinate2DMake(track.ne.coordinate.latitude, track.sw.coordinate.longitude), bottomRightCoordinate: CLLocationCoordinate2DMake(track.sw.coordinate.latitude, track.ne.coordinate.longitude))

    // Add the mapView to the view just to see if it displays correctly. (It does!)
    mapView.fitBounds(boundingBox, withPadding: CGSizeMake(20, 20))
