Question

我想将TabBarIOS集成到本机应用程序中。比如按下按钮后显示到TabBarIOS。但是当我跑步时它会粉碎。

在 index.ios.js

中

'use strict';

import React from 'react';
import {
  AppRegistry,
} from 'react-native';

import myTabBar from './ios/tab/MyTab.js'
AppRegistry.registerComponent('myTabBar', () => myTabBar);

原生代码：

let rootView = RCTRootView(
        bundleURL: jsCodeLocation,
        moduleName: "myTabBar",
        initialProperties: nil,
        launchOptions: nil
    )
let vc = UIViewController()
vc.view = rootView
self.presentViewController(vc, animated: true, completion: nil)

错误：

感谢您的帮助！

看到它无法找到RCTImageView，我猜你还没有包含该库。

如果您正在使用CocoaPods，那么您希望它包含RCTImage，并让它看起来像：

platform :ios, '9.0'

target 'YourApp' do
  use_frameworks!

  # React Native
  pod 'React', :path => 'node_modules/react-native', :subspecs => [
    'Core',
    'RCTImage',
  ]
end

反正有没有使用React Native向TabBarIOS提供本机控制器？
