wix-react-native-navigation - 应用程序尚未注册(react-native-navigation v2)

Question

react 原生导航 v2 问题。

我的应用程序以 index.js 开头，它也注册到 AppDelegate 中。以下是详细信息:

import { AppRegistry } from 'react-native';
const { start } = require('./src/app');
start();

这里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: {
            startApp: {
                y: {
                    from: 1000,
                    to: 0,
                    duration: 500,
                    interpolation: 'accelerate',
                },

                        interpolation: 'accelerate'
                    }
                },
                bottomTabs: {

    Navigation.setRoot({
        root: {

                children: [
                    {

                        }
                    }
                ]
            }
        }
    });
});
}


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"
 },

我在 V2 中也遇到过类似的问题，问题是由于没有删除 didFinishLaunchingWithOptions 中的 rootView 设置引起的。 AppDelegate.m 中的方法

- (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 Application XXXXXXXXXX 未注册错误 . https://wix.github.io/react-native-navigation/v2/#/docs/Installing中的IOS说明应该强调的是，必须删除这些与 rootView 相关的行。

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;
}
