Question

我们正在尝试将我们的React Native应用程序从版本55更新到57.7。确实很痛苦，但它同时在ios和android上构建。在Android上运行正常，但在ios上，它被固定在黑屏上。看起来像这个问题，Getting an entire black screen when running react-native run-ios。一样。没运气。我什至尝试在index.js（仍然是黑屏）中进行简单查看。在js或xcode上的开发人员控制台中都没有错误。不知道我做错了什么。

我们按照官方程序进行了以下链接升级： https://github.com/react-native-community/react-native-releases/blob/master/CHANGELOG.md

和我的代码如下： appDelegate.m

  #import "AppDelegate.h"
    #import <React/RCTBundleURLProvider.h>
    #import <React/RCTPushNotificationManager.h>        
    #import <React/RCTRootView.h>
    #import <FBSDKCoreKit/FBSDKCoreKit.h>
    #import <RNGoogleSignin/RNGoogleSignin.h>
    #import "Orientation.h"
    #import <ReactNativeNavigation/ReactNativeNavigation.h>

    @implementation AppDelegate

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {

      NSURL *jsCodeLocation;

      #ifdef DEBUG
      jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
      #else
      jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
      #endif

      self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
      self.window.backgroundColor = [UIColor whiteColor];


      [ReactNativeNavigation bootstrap:jsCodeLocation launchOptions:launchOptions];
      [[FBSDKApplicationDelegate sharedInstance] application:application
                               didFinishLaunchingWithOptions:launchOptions];
      return YES;
    }

索引js

import {AppRegistry, View, Text} from 'react-native';

AppRegistry.registerComponent(APP_NAME, () => {
return(
 <View style={{ height:500, width:300, backgroundColor:"orange"}}>
  <Text>hello</Text>
</View>
);
