React-Native(iOS)中的Google地图

Question

我的目标是在React Native中显示Google Map.我见过将Google Maps SDK与UIMapView或MapBox地图一起使用的示例,但这不是我要找的.

我目前没有错误.这是我的代码:

index.ios.js

'use strict';
import React, {
    AppRegistry,
    Component,
    StyleSheet,
    Text,
    View
} from 'react-native';
import GoogleMaps from './ios/GoogleMaps.js';

class RCTGoogleMaps extends Component {
    constructor(props) {
        super(props);
    }

    render() {
        return (
            <View style={styles.container}>
                <GoogleMaps style={styles.map}/>
            </View>
        );
    }
}

const styles = StyleSheet.create({
    container: {
        flex: 1,
        justifyContent: 'center',
        alignItems: 'center',
        backgroundColor: '#F5FCFF'
    },
    map: {
        height: 500,
        width: 300,
        marginLeft: 50
    }
});

AppRegistry.registerComponent('RCTGoogleMaps', () => RCTGoogleMaps);

IOS/GoogleMaps.js

var {requireNativeComponent} = require('react-native');
module.exports = requireNativeComponent('RCTGoogleMapViewManager', null);

IOS/RCTGoogleMapViewManager.h

#ifndef RCTGoogleMapViewManager_h
#define RCTGoogleMapViewManager_h

#import <Foundation/Foundation.h>
#import "RCTViewManager.h"
#import <UIKit/UIKit.h>

@interface RCTGoogleMapViewManager : RCTViewManager<UITextViewDelegate>
@end

#endif /* RCTGoogleMapViewManager_h */

IOS/GoogleMapViewManager.m

#import <Foundation/Foundation.h>
#import "RCTGoogleMapViewManager.h"
#import "RCTBridge.h"
#import "RCTEventDispatcher.h"
#import "UIView+React.h"
@import GoogleMaps;

@implementation RCTGoogleMapViewManager
  RCT_EXPORT_MODULE()

- (UIView *)view {
  GMSMapView *mapView_;
  // Create a GMSCameraPosition that tells the map to display the
  // coordinate -33.86,151.20 at zoom level 6.
  GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                          longitude:151.20
                                                               zoom:6];
  mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
  mapView_.myLocationEnabled = YES;
  UIView *newView_ = mapView_;
  //self.view = mapView_;

  // Creates a marker in the center of the map.
  GMSMarker *marker = [[GMSMarker alloc] init];
  marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
  marker.title = @"Sydney";
  marker.snippet = @"Australia";
  marker.map = mapView_;
  return newView_;
}

RCT_EXPORT_VIEW_PROPERTY(text, NSString)

@end

组件周围有红色边框,但内部没有任何显示.我是React Native的新手,也是StackOverflow的新手.不幸的是,在我获得更多声誉之前,他们不会让我上传截图.

有一条线我怀疑要关闭,但不知道要改变它.RCTGoogleMapViewManager.h中的第8行说"@interface RCTGoogleMapViewManager:RCTViewManager".我已将UITextViewDelegates用于其他自定义组件,但此映射不是TextView.可能是这样,但我不知道.

任何帮助都将不胜感激.

您查看过https://github.com/peterprokop/ReactNativeGoogleMaps吗？它看起来相当初级，但对您来说仍然非常有用。
