如何在 iOS 中以编程方式下载地图

Question

正在处理 Mapkit 框架。

我想通过编程方式下载地图的特定区域。

并且还想在 offline.How 中显示下载的地图，我可以这样做吗？

任何人都可以帮助我，将不胜感激。

谢谢。

简而言之，MapKit 无法通过。

我已经使用了第三方 SDK。请查看下面的 link

https://www.mapbox.com/developers/

Objective C

@import Mapbox;

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    MGLMapView *mapView = [[MGLMapView alloc] initWithFrame:self.view.bounds];

    mapView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

    // set the map's center coordinates and zoom level
    [mapView setCenterCoordinate:CLLocationCoordinate2DMake(40.7326808, -73.9843407)
                       zoomLevel:12
                        animated:NO];

    [self.view addSubview:mapView];
}

@end

Swift

import Mapbox

class ViewController: UIViewController, MGLMapViewDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()

        let mapView = MGLMapView(frame: view.bounds)
        mapView.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]

        // set the map's center coordinate
        mapView.setCenterCoordinate(CLLocationCoordinate2D(latitude: 40.7326808,
                                                           longitude: -73.9843407),
                                    zoomLevel: 12, animated: false)
        view.addSubview(mapView)
    }
}
