如何在原有Xcode项目中集成ReactNative模块

### 1.搭建开发环境 ###

安装nvm, homebrew,node.js,react-native-cli,CocoaPods

### 2.安装React Native ###

可以去生成一个例子程序，然后把package.json文件拿过来

{
      "name": "NativeRNApp",
      "version": "0.0.1",
      "private": true,
      "scripts": {
        "start": "node node_modules/react-native/local-cli/cli.js start"
      },
      "dependencies": {
        "react": "15.2.1",
        "react-native": "0.29.2"
      }
    }

其中name就是项目名称，切换到项目目上一层目录，执行npm install命令

### 3.创建index.ios.js文件 ###

同样可以是从生成的例子程序拷贝过来

### 4.CocoaPods集成React Native ###

platform :ios,’8.0’
    
    target “testReact” do
    
    pod 'React', :path => ‘/Users/liuyinghui/myFirstRectProject/node_modules/react-native', :subspecs => [
     'Core',
      'ART',
      'RCTActionSheet',
      'RCTAdSupport',
      'RCTGeolocation',
      'RCTImage',
      'RCTNetwork',
      'RCTPushNotification',
      'RCTSettings',
      'RCTText',
      'RCTVibration',
      'RCTWebSocket',
      'RCTLinkingIOS',
    ]
    end

其中 target是你的项目名称，放到工程目录下。然后执行 pod install命令。

### 5.对原生项目进行修改 ###

引入头文件

#import <React/RCTBundleURLProvider.h>
    #import <React/RCTRootView.h>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
        // Override point for customization after application launch.
        NSURL *jsCodeLocation;
        
        jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
        
        RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                            moduleName:@"模块名称"
                                                     initialProperties:nil
                                                         launchOptions:launchOptions];
        
        rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];
        
        CGRect rect=CGRectMake(0, 0,[UIScreen mainScreen].bounds.size.width , [UIScreen mainScreen].bounds.size.height);
        self.window = [[UIWindow alloc] initWithFrame:rect];
        UIViewController *rootViewController = [UIViewController new];
        rootViewController.view = rootView;
        self.window.rootViewController=rootViewController;
        [self.window makeKeyAndVisible];
        return YES;
        
    }

运行就可以了
