ios - react-navigation 正在 iOS 模拟器上工作，但在 iOS 真实设备上面临导航问题

Question

react - 导航适用于 iOS 和 android 模拟器以及 android 真实设备，但不适用于 iOS 真实设备

我正在使用堆栈导航器，在堆栈导航器内使用抽屉导航器和选项卡导航器，但在运行项目时，它正在 iOS 和 android 模拟器和 android 真实设备上工作，但在 iOS 真实设备上不工作

我正在使用“反应导航”：“^3.9.1”

const AppContainer = createAppContainer(AppSwitchNavigator)
const AppSwitchNavigator = createStackNavigator({ // here i am create stack navigator and inside stack navigator used drawer navigator for dashboard 

    welcome: {
