Answer 1

如何使用这段代码
import {UrlTile} from 'react-native-maps';

<MapView region={this.state.region} onRegionChange={this.onRegionChange}>
  <UrlTile
    /**
     * 瓦片服务器的url模板。运行时将替换{x} {y} {z}模式
     * 例如，http://c.tile.openstreetmap.org/{z}/{x}/{y}.png
     */
    urlTemplate={this.state.urlTemplate}
    /**
     * 此瓦片叠加层的最大缩放级别。对应于MKTileOverlay中的maximumZ设置。仅适用于iOS。
     */
    maximumZ={19}
    /**
     * flipY允许使用具有倒置的y坐标（地图左下角为原点）的瓦片。默认值为false。
     */
    flipY={false}
  />
</MapView>;
