react-native-splash-screen中SplashScreen.hide()在iOS设备无法生效求助

1. 修复AppDelegate中的窗口初始化逻辑 #

你的AppDelegate代码缺少UIWindow和根视图控制器的初始化步骤，导致RNSplashScreen无法正确挂载到视图层级中。修改后的代码如下：

#import <Firebase.h>
#import "AppDelegate.h"
#import "RNSplashScreen.h"
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  [FIRApp configure];
  self.moduleName = @"spengucomputercourse";
  self.initialProps = @{};

  // 初始化窗口与根视图控制器
  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:self.sourceURLForBridge:nil
                                                      moduleName:self.moduleName
                                               initialProperties:self.initialProps
                                                   launchOptions:launchOptions];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];

  [RNSplashScreen show]; // 确保在窗口设置完成后调用
  return YES;
}

- (NSURL *)sourceURLForBridge:(RCTBridge *)bridge
{
#if DEBUG
  return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index"];
#else
  return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
#endif
}
@end

2. 验证启动页Storyboard配置 #

打开Xcode，完成以下检查：

• 找到LaunchScreen.storyboard，选中主视图控制器
• 在Identity Inspector面板中，将Storyboard ID设置为LaunchScreen（与库默认配置一致）
• 确保视图控制器的Class为UIViewController，不要使用自定义类

3. 调整JS端隐藏时机（可选） #

如果RN初始化较慢，过早调用hide()可能失效，可以监听AppState在应用激活后再隐藏：

import React, {useEffect} from 'react';
import Navigations from './src/Routes/Navigations';
import SplashScreen from 'react-native-splash-screen';
import {LogBox, AppState} from 'react-native';

const App = () => {
  LogBox.ignoreAllLogs();
  useEffect(() => {
    const appStateListener = AppState.addEventListener('change', (state) => {
      if (state === 'active') {
        SplashScreen.hide();
        appStateListener.remove(); // 仅执行一次
      }
    });

    return () => appStateListener.remove();
  }, []);

  return <Navigations />;
};

4. 重新安装iOS依赖 #

进入iOS目录执行pod安装，确保库的原生代码正确集成：

cd ios && pod install && cd ..
