集成到以 RN 为主的项目
本文档仅适用于 RN0.60 以上版本
你想用 React Native 实现大部分业务,原生代码主要起到搭桥的作用。
假设你是通过 npx @react-native-community/cli init MyApp 创建的项目,目录结构是这样的:
MyApp/
├─ android/
├─ ios/
├─ node_modules/
├─ package.json
也可以通过
npx react-native-create-app <AppName>命令来创建
react-native-create-app 会自动创建一个 RN 项目, 并集成 hybrid-navigation。
添加依赖
npm install hybrid-navigation --save
# or
yarn add hybrid-navigation
RN 项目配置
打开 index.js 这个文件,通常,它就在 package.json 旁边。
以前,你是这么注册 React 组件
import { AppRegistry } from 'react-native';
import App from './App';
import { name as appName } from './app.json';
AppRegistry.registerComponent(appName, () => App);
现在,你需要像下面那样
import Navigation, { BarStyleDarkContent } from 'hybrid-navigation';
import App from './App';
// 配置全局样式
Navigation.setDefaultOptions({
topBarStyle: BarStyleDarkContent,
});
// 重要必须
Navigation.startRegisterComponent();
// 注意,你的每一个页面都需要注册
Navigation.registerComponent('App', () => App);
// 重要必须
Navigation.endRegisterComponent();
// 通过 Navigation.setRoot 设置 UI 层级
Navigation.setRoot({
stack: {
children: [{ screen: { moduleName: 'App' } }],
},
});
setRoot 具体用法请查看 Navigation.setRoot
另外有一个需要注意的地方,hybrid-navigation 接管了状态栏,如果代码里面有使用 <StatusBar /> 组件,需要移除。
- <StatusBar barStyle={isDarkMode ? 'light-content' : 'dark-content'} />
支持 Redux
想要为每个页面都注入相同的属性,可以利用 Navigation.startRegisterComponent() 这个方法,它接受一个 HOC 作为参数。
想要支持 Redux,像下面这样配置即可
function withRedux(WrappedComponent) {
return class ReduxProvider extends React.Component {
// 注意复制 navigationItem
static navigationItem = (WrappedComponent as any).navigationItem
static displayName = `withRedux(${WrappedComponent.displayName})`
render() {
return (
<Provider store={store}>
{/* 注意传递 props 属性 */}
<WrappedComponent {...this.props} />
</Provider>
)
}
}
}
Navigation.startRegisterComponent(withRedux)
其中 withRedux 就是一个 HOC
Android 项目配置
修改 MainActivity.java 文件
- import com.facebook.react.ReactActivity;
+ import com.reactnative.hybridnavigation.ReactAppCompatActivity;
- public class MainActivity extends ReactActivity {
+ public class MainActivity extends ReactAppCompatActivity {
- @Override
- protected String getMainComponentName() {
- return "MyApp";
- }
}
修改后一般长下面这个样子:
package com.myapp69;
import com.reactnative.hybridnavigation.ReactAppCompatActivity;
public class MainActivity extends ReactAppCompatActivity {
// 空空如也
}
修改 MainApplication.java 文件
import com.facebook.react.ReactNativeHost;
+ import com.reactnative.hybridnavigation.ReactManager;
public void onCreate() {
super.onCreate();
ReactNativeApplicationEntryPoint.loadReactNative(this);
+ ReactManager reactManager = ReactManager.get();
+ reactManager.install(getReactHost());
}
运行项目,如果发现 TopBar 的高度不正常,记得移除所有 <StatusBar /> 组件
iOS 项目配置
更新 pod 依赖
cd ios & pod install
修改 AppDelegate.h 文件,修改后大概长下面这个样子
#import <UIKit/UIKit.h>
@interface AppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow *window;
@end
修改 AppDelegate.m 文件,修改后大概长下面这个样子
#import "AppDelegate.h"
#import <React-RCTAppDelegate/RCTDefaultReactNativeFactoryDelegate.h>
#import <React-RCTAppDelegate/RCTReactNativeFactory.h>
#import <ReactAppDependencyProvider/RCTAppDependencyProvider.h>
#import <React/RCTLinkingManager.h>
#import <React/RCTBundleURLProvider.h>
#import <React/RCTLog.h>
#import <React/RCTDevMenu.h>
#import <HybridNavigation/HybridNavigation.h>
@interface ReactNativeDelegate : RCTDefaultReactNativeFactoryDelegate
@end
@implementation ReactNativeDelegate
- (NSURL *)bundleURL {
#if DEBUG
return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index"];
#else
return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
#endif
}
@end
@interface AppDelegate () <HBDReactBridgeManagerDelegate>
@property (strong, nonatomic) RCTRootViewFactory *rootViewFactory;
@property (strong, nonatomic) id<RCTReactNativeFactoryDelegate> reactNativeDelegate;
@property (strong, nonatomic) RCTReactNativeFactory *reactNativeFactory;
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
RCTSetLogThreshold(RCTLogLevelInfo);
ReactNativeDelegate *delegate = [[ReactNativeDelegate alloc] init];
RCTReactNativeFactory *factory = [[RCTReactNativeFactory alloc] initWithDelegate:delegate];
delegate.dependencyProvider = [[RCTAppDependencyProvider alloc] init];
self.reactNativeDelegate = delegate;
self.reactNativeFactory = factory;
self.rootViewFactory = factory.rootViewFactory;
[self.rootViewFactory initializeReactHostWithLaunchOptions:launchOptions devMenuConfiguration:[RCTDevMenuConfiguration defaultConfiguration]];
[[HBDReactBridgeManager get] installWithReactHost:self.rootViewFactory.reactHost];
// register native modules
[[HBDReactBridgeManager get] registerNativeModule:@"NativeModule" forViewController:[NativeViewController class]];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"LaunchScreen" bundle:nil];
UIViewController *rootViewController = [storyboard instantiateInitialViewController];
self.window.windowLevel = UIWindowLevelStatusBar + 1;
self.window.rootViewController = rootViewController;
[self.window makeKeyAndVisible];
return YES;
}
- (void)reactModuleRegisterDidCompleted:(HBDReactBridgeManager *)manager {
}
@end
修改 Info.plist 文件

运行项目,如果出现关于状态栏的错误提示,记得移除所有 <StatusBar /> 组件。
