我是 ReactNative 的新手。 在我当前的应用程序中，深度链接是经过编码的，并且通过 appDelegate 完成时运行良好。 后来，应用程序也支持Carplay，因此引入了sceneDelegate来处理多个场景。
之后，每当调用深度链接时
这里有什么问题， 即使应用程序已从内存中删除，我需要更改/添加哪些内容才能使应用程序在所需位置启动。
这是我的应用程序委托。

这是我的 info.plist 代码。

它在 Android 构建中按预期工作，但仅在 iOS 构建中存在问题。 如果我切换回没有 scenedelegate 的 appDelegate，那么我的 Carplay 应用程序不会启动。
任何帮助将不胜感激。
谢谢。
我在@sonle的帮助下解决了问题
通过增加执行深层链接的时间，解决了问题。
DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
handleDeepLink(deeplink)
}
感谢Sonle的指导。
