MKMapView中心和放大

我在一个项目上使用MKMapView,并希望将地图置于坐标上并放大.就像谷歌地图有:

GMSCameraPosition.camera(withLatitude: -33.8683,
                                  longitude: 151.2086,
                                  zoom: 6)

有没有Mapkit方法呢？

您将创建一个MKCoordinateRegion对象并将其设置为MKMapView对象上的区域.

MKCoordinateRegion mapRegion;   
CLLocationCoordinate2D coordinate;
coordinate.latitude = 0;
coordinate.longitude = 0;    
mapRegion.center = coordinate;
mapRegion.span.latitudeDelta = 0.2;
mapRegion.span.longitudeDelta = 0.2;

[mapView setRegion:mapRegion animated: YES];

这是我用于将地图置于预定义CLLocation使用中心的方法MKCoordinateRegion.

func centerMapOnLocation(_ location: CLLocation, mapView: MKMapView) {
    let regionRadius: CLLocationDistance = 1000
    let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate,
        regionRadius * 2.0, regionRadius * 2.0)
    mapView.setRegion(coordinateRegion, animated: true)
}
