nwa*_*les 10 ios cocoapods react-native
我已经挖掘了许多帖子试图使用cocoapods为本地ios库设置一个本机项目,但我不可避免地#import <React/RCTBundleURLProvider.h>在我的AppDelegate.m文件中的语句中丢失了一个错误的文件.
什么是使用反应原生的可可豆荚的正确方法?在这篇文章发表时,我目前的RN版本是0.43.4,而我正在使用Xcode 8.2.1.
这是我的过程,好奇我可能会出错:
1)在终端中,我使用创建一个新项目 react-native init TestProject
2)我pod init在该项目的ios目录中运行
3)我在podFile中添加了一个依赖项并运行 pod install
4)安装过程成功,但我看到一个警告我的目标override the 'OTHER_LDFLAGS'并且它建议我$(inherit)在Xcode中的链接器标志中使用.
5)因此,基于此SO帖子,我添加$(inherited)到Project> TestProject> BuildSettings> links> Other Linker Flags,否则为空.我还检查并发现它$(inherited)已经存在于目标>测试项目>构建设置>链接>其他链接器标志和预处理器宏中.
6)此时我在语句中看到React/RCTBundleURLProvider.h文件未找到错误#import <React/RCTBundleURLProvider.h>AppDelegate.m
7)基于此SO帖子,我尝试删除node modules目录并返回终端运行npm install并完成'react-native upgrade'.当它问我是否要替换AppDelegate.m和project.pbxproj文件,我说是的.
8)回到xCode我清理我的构建但仍然有步骤6导入的错误 <React/RCTBundleURLProvider.h>

我只是从干净的Xcode项目开始制作整个过程.通常我简单地创建RN应用程序,弹出然后转换为cocoapods ios部分.它主要基于RN文档:http://facebook.github.io/react-native/docs/0.51/integration-with-existing-apps.html
所以环境:macOS Sierra,Xcode 9.2,RN 0.51.0
项目名称:MyApp
cd MyApp,mkdir ios,mv MyApp* ios(移动所有iOS相关的文件到iOS子文件夹)package.json在项目的根文件夹中创建(非常基本)
{
"name": "MyApp",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node node_modules/react-native/local-cli/cli.js start"
},
"dependencies": {
"react": "16.0.0",
"react-native": "0.51.0"
},
"devDependencies": {
"babel-jest": "22.0.4",
"babel-preset-react-native": "4.0.0"
}

您可以添加/删除React subspecs以包含/删除RN功能,这是一个艰难的过程,因为RN组件不完全独立.
pod install (将pod整合到项目中,将创建MyApp.xcworkspace,它应该用于编译应用程序)open MyApp.xcworkspace,构建和运行,应用程序应该仍然有效用这个片段替换你的AppDelegate.m:
#import "AppDelegate.h"
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
#if RCT_DEV
#import <React/RCTDevLoadingView.h>
#endif
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
RCTBundleURLProvider* provider = [RCTBundleURLProvider sharedSettings];
NSURL* jsCodeLocation = [provider jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
RCTBridge *bridge = [[RCTBridge alloc] initWithBundleURL:jsCodeLocation moduleProvider:nil launchOptions:launchOptions];
#if RCT_DEV
[bridge moduleForClass:[RCTDevLoadingView class]];
#endif
RCTRootView *rootView = [[RCTRootView alloc] initWithBridge:bridge moduleName:@"MyApp" initialProperties:@{}];
rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
UIViewController *rootViewController = [UIViewController new];
rootViewController.view = rootView;
self.window.rootViewController = rootViewController;
[self.window makeKeyAndVisible];
return YES;
}

MyApp/index.js使用此代码创建(来自RN模板):
import { AppRegistry } from 'react-native';
import App from './App';
AppRegistry.registerComponent('MyApp', () => App);

创建MyApp/App.js:
import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
export default class App extends React.Component {
render() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>
Welcome to React Native!

npm start从根项目文件夹启动打包程序(MyApp)main.jsbundle这样它就可以在没有packager dev服务器的情况下运行.使用以下内容向MyApp目标的构建阶段添加脚本步骤:
export NODE_BINARY=node
../node_modules/react-native/scripts/react-native-xcode.sh
