iOS原生项目和React Native交互

一、不太成功的实现

package.json文件:

{
  "name": "myRactNative",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "android": "react-native run-android",
    "ios": "react-native run-ios",
    "start": "react-native start",
    "test": "jest",
    "lint": "eslint ."
  },
  "dependencies": {
    "react": "16.3.0",
    "react-native": "^0.63.4"
  },
  "devDependencies": {
    "@babel/core": "^7.8.7",
    "@babel/runtime": "^7.8.7",
    "@react-native-community/eslint-config": "^0.0.7",
    "babel-jest": "^25.1.0",
    "eslint": "^6.8.0",
    "jest": "^25.1.0",
    "metro-react-native-babel-preset": "^0.58.0",
    "react-test-renderer": "16.9.0"
  },
  "jest": {
    "preset": "react-native"
  }
}

Profile文件：

platform :ios, '10.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

target 'ReactNativeIOSDemo' do
  # Pods for ReactNativeIOSDemo

  use_native_modules!
end

重点就是以上两个文件配置了，实话实说踩了好多坑啊，还好最后解决了，项目也跑起来了，但是。。。。。。RN的页面怎么也不显示。。。。

最后，我用命令脚手架创建的RN的项目，再在iOS项目里写和RN的传值，完美的实现。

二、成功的实现：

创建RN项目；
运行js代码； npm start
iOS原生给RN传值；

具体iOS传值代码如下：

//
//  ViewController.m
//  rnDemo
//
//  Created by 彭思 on 2020/12/4.
//

#import "ViewController.h"
#import 
#import 
#import 

#ifdef FB_SONARKIT_ENABLED
#import 
#import 
#import 
#import 
#import 
#import 

static void InitializeFlipper(UIApplication *application) {
  FlipperClient *client = [FlipperClient sharedClient];
  SKDescriptorMapper *layoutDescriptorMapper = [[SKDescriptorMapper alloc] initWithDefaults];
  [client addPlugin:[[FlipperKitLayoutPlugin alloc] initWithRootNode:application withDescriptorMapper:layoutDescriptorMapper]];
  [client addPlugin:[[FKUserDefaultsPlugin alloc] initWithSuiteName:nil]];
  [client addPlugin:[FlipperKitReactPlugin new]];
  [client addPlugin:[[FlipperKitNetworkPlugin alloc] initWithNetworkAdapter:[SKIOSNetworkAdapter new]]];
  [client start];
}
#endif

#import "ViewController1.h"
@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
  self.view.backgroundColor = [UIColor redColor];
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
  NSArray *imageList = @[@"http://foo.com/bar1.png",
                         @"http://foo.com/bar2.png"];

  NSDictionary *props = @{@"urls" : imageList};
  RCTBridge *bridge = [[RCTBridge alloc] initWithDelegate:self launchOptions:nil];
  
  // 没有打包main.jsbundle的代码
//  RCTRootView *rootView = [[RCTRootView alloc] initWithBridge:bridge
//                                                     moduleName:@"rnDemo"
//                                              initialProperties:props];
  
  // 使用main.jsbundle打包
  NSURL *jsCodeLocation2 = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
  RCTRootView *rootView = [[RCTRootView alloc]initWithBundleURL:jsCodeLocation2 moduleName:@"rnDemo" initialProperties:props launchOptions:nil];

  ViewController1 *vc = [[ViewController1 alloc]init];
  vc.view = rootView;
  [self presentViewController:vc animated:YES completion:nil];
}


- (NSURL *)sourceURLForBridge:(RCTBridge *)bridge {
#if DEBUG
  return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
#else
  return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
#endif
}

@end

RN代码取iOS原生传过去的值：

export default class App extends React.Component {
  renderImage(imgURI) {
    return (
      {imgURI}
    );
  }
  render() {
    return (
      
        {this.props.urls.map(this.renderImage)}
      
    );
  }
}

RN页面正常跳转，传递的值正常显示。

PS：RN真的好坑啊，环境真的也是搞得想死。。。。。。

确实最后是版本不一致导致的，修改版本一致解决。
