【中文标题】应用尚未注册（react-native-navigation v2）【英文标题】：Application has not been registered (react-native-navigation v2) 【发布时间】：2018-11-13 23:35:24 【问题描述】：React 原生导航 v2 问题。
我的应用程序以 index.js 开头，并且也注册到 AppDelegate 中。详情如下：
import AppRegistry from 'react-native';
const start = require('./src/app');
start();
这里是 app.js：
```
const Navigation = require('react-native-navigation');
const registerScreens = require('./screens');
const Platform = require('react-native');
if (Platform.OS === 'android')
alert = (title) =>
Navigation.showOverlay(
component:
name: 'navigation.playground.alert',
passProps:
title
,
options:
overlay:
interceptTouchOutside: true
);
;
function start()
registerScreens();
Navigation.events().registerAppLaunchedListener(() =>
Navigation.setDefaultOptions(
_animations:

);
Navigation.setRoot(
root:
stack:
id: 'TEST',
children: [
component:
name: 'rp.welcome'
]
);
);
module.exports =
start
;
屏幕注册：
const Navigation = require('react-native-navigation');
const WelcomeScreen = require('./WelcomeScreen');
const Authentication = require('./Authentication').default;
const Tutorial = require('./Tutorial');
function registerScreens()
Navigation.registerComponent(`rp.welcome`, () => WelcomeScreen);
Navigation.registerComponent(`rp.tutorial`, ()=>Tutorial);
Navigation.registerComponent(`rp.authentication.super`,()=> Authentication);
module.exports =
registerScreens
;
环境：
"dependencies":
"react": "16.3.1",
"react-native": "0.55.4",
"react-native-navigation": "^2.0.2314",
"react-native-video": "^2.1.1",
"rn-viewpager": "^1.2.9"
,
【问题讨论】：
【参考方案1】：我已经通过这样放置组件的字符串名称来解决这个问题：
而不是：component: YourComponent
应该是：
component:
name: 'YourComponent'
完整代码如下：
Navigation.events().registerAppLaunchedListener(() =>
Navigation.setRoot(
root:
stack:
children: [
component:
name: 'YourComponent'
]
)
);
另外，如果你 push 或 setStackRoot，你应该总是使用组件名： 例如
component:
name: 'YourComponent'

【参考方案2】：我在 V2 中遇到过类似的问题，问题是由于没有删除 AppDelegate.m 中 didFinishLaunchingWithOptions 方法中的 rootView 设置。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
NSURL *jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
[ReactNativeNavigation bootstrap:jsCodeLocation launchOptions:launchOptions];
RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
moduleName:@"XXXXXXXXXX"
initialProperties:nil
launchOptions:launchOptions];
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;
如果你把它们留在里面，会导致应用程序 XXXXXXXXXX 未注册错误。 https://wix.github.io/react-native-navigation/v2/#/docs/Installing中的ios指令应该强调这些rootView相关的行一定要去掉。
正确的 AppDelegates.m 应该是这样的：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
NSURL *jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
[ReactNativeNavigation bootstrap:jsCodeLocation launchOptions:launchOptions];
return YES;
【讨论】：
我不得不说这是我的问题的实际答案。我在网上到处查看每个问题，我很高兴这个答案甚至存在。感谢 RedGiant，我希望其他人也会因为自己的心理原因而偶然发现这一点【参考方案3】：我遇到了同样的问题，但只在 Android 上。原来我错过了配置过程中的一步。
在 MainActivity.java 中它应该扩展 com.reactnativenavigation.NavigationActivity 而不是 ReactActivity。
