xcode – 如何在MKMapView Swift中放大图钉

>确定敲击了哪个引脚

如果您在项目中正确启动了mapView(以视图作为其委托),则可以使用mapView(_:didSelectAnnotationView:)方法完成上述两点,如下所示：

func mapView(mapView: MKMapView,didSELEctAnnotationView view: MKAnnotationView) {

        // get the particular pin that was tapped
        let pinToZoomOn = view.Annotation

        // optionally you can set your own boundaries of the zoom
        let span = MKCoordinateSpanMake(0.5,0.5)

        // or use the current map zoom and just center the map
        // let span = mapView.region.span

        // Now move the map
        let region = MKCoordinateRegion(center: pinToZoomOn!.coordinate,span: span)
        mapView.setRegion(region,animated: truE)
}

此方法告诉委托(您的视图最有可能)选择了一个地图注释视图并移动(和/或缩放)到该坐标区域.
