无法从 react-native-maps 渲染 <MapView/>

Question

我正在尝试使用示例中的坐标显示原生地图，但出现错误：

*注 使用 ios 和真实设备进行调试

错误：

Could not inset compass from edges 9
Could not inset scale from edge 
Could not inset legal attribution from corner 4

代码：

class Map extends Component {
constructor(props) {
    super(props);
}
render() {   
    console.log('map render')    
    return (
            <MapView 
            provider={null}
            initialRegion={{
            latitude: 37.78825,
            longitude: -122.4324,
            latitudeDelta: 0.0922,
            longitudeDelta: 0.0421,
            }}
        />
    );
}}

样式有问题。我能够使用以下代码修复它：

render() {
    return (
      <View style={styles.container}>
        <MapView
        style={styles.map}
          provider={null}
          initialRegion={{
            latitude: 37.78825,
            longitude: -122.4324,
            latitudeDelta: 0.0922,
            longitudeDelta: 0.0421,
          }}
        />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    position: 'absolute',
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
    justifyContent: 'flex-end',
    alignItems: 'center',
  },
  map: {
    position: 'absolute',
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
  },
});
