React Native iOS相互调用

打开iOS工程

• 在你需要用React Native 的地方添加UIButton
• 创建react native 的容器view

#import <UIKit/UIKit.h>

@interface ReactView : UIView

@end

#import "ReactView.h"
#import <React/RCTRootView.h>//  导入reactView

@implementation ReactView

- (instancetype)initWithFrame:(CGRect)frame
{
    if (self = [super initWithFrame:frame]) {
        NSURL *jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.bundle?platform=ios"];
        RCTRootView *rootView =
        [[RCTRootView alloc] initWithBundleURL: jsCodeLocation
                                    moduleName: @"MyApp"
                             initialProperties:nil
                                 launchOptions: nil];
        
        [self addSubview:rootView];
        
        rootView.frame = self.bounds;
    }
    return self;
}
@end

项目目录下找到index.js

我是通过sublime Text 3 编写的，推荐几个适合React-native的插件

react-native-snippets
ReactJS

index.js作为一个类似main函数，所以以简洁为准

/**
 * Sample React Native App
 * https://github.com/facebook/react-native
 * @flow
 */

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  TouchableOpacity
} from 'react-native';

import Root from './App/root';
// MyApp 必须要和工程里边的moduleName:一致
/*
- (instancetype)initWithBridge:(RCTBridge *)bridge
                    moduleName:(NSString *)moduleName
             initialProperties:(NSDictionary *)initialProperties NS_DESIGNATED_INITIALIZER;
*/
AppRegistry.registerComponent('MyApp', () => Root);

在目录中创建App文件夹并且创建root.js文件作为根文件

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  TouchableOpacity,  
  NativeModules,
  Button,
  Alert,
  
} from 'react-native';
var WSReactRout = NativeModules.WSReactRout;
export default class MyApps extends Component {
  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>
          Welcome to React Native!
        </Text>
        <Text style={styles.instructions}>
          To get started, edit index.ios.js
        </Text>
        <Text style={styles.instructions}>
          Press Cmd+R to reload,{'\n'}
          Cmd+D or shake for dev menu
        </Text>     

        <View style={styles.buttonContainer}>
          <Button
            onPress={this._onPressButton}
            title="Press Me"
            style={styles.container}
          />
        </View>

      </View>


    );
  }

        _onPressButton() {

            WSReactRout.WSJumpToVC('YWS');
        }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
   buttonContainer: {
    margin: 20
  },
});

在Xcode创建一个文件继承NSObject
.h 文件

#import <Foundation/Foundation.h>
#import <React/RCTBridgeModule.h>
#import <React/RCTLog.h>
@interface WSReactRout : NSObject<RCTBridgeModule>

@end

.m文件

#import "WSReactRout.h"

@implementation WSReactRout
RCT_EXPORT_MODULE()
//RN跳转原生界面
RCT_EXPORT_METHOD(WSJumpToVC:(NSString *)msg){
    
    NSLog(@"RN传入原生界面的数据为:%@",msg);
    
}

// 接收传过来的 NSString
RCT_EXPORT_METHOD(addEventOne:(NSString *)name){
    NSLog(@"接收传过来的NSString+NSString: %@", name);
    //进行页面跳转

}

@end
