React-Native-Map:如何使用animateCamera和setCamera

npm install react-native-maps --save

import MapView, { Camera } from 'react-native-maps';

render() {
  return (
    <MapView
      initialRegion={{
        latitude: 37.78825,
        longitude: -122.4324,
        latitudeDelta: 0.0922,
        longitudeDelta: 0.0421,
      }}
    />
  );
}

animateToNewLocation = () => {
  const newCamera = {
    center: {
      latitude: 37.78825,
      longitude: -122.4324,
    },
    zoom: 12,
  };

  this.mapView.animateCamera(newCamera);
}

render() {
  return (
    <MapView
      ref={ref => this.mapView = ref}
      ...
    />
  );
}

setNewLocation = () => {
  const newCamera = {
    center: {
      latitude: 37.78825,
      longitude: -122.4324,
    },
    zoom: 12,
  };

  this.mapView.setCamera(newCamera);
}

render() {
  return (
    <MapView
      ref={ref => this.mapView = ref}
      ...
    />
  );
}
