警告信息

WARN Found screens with the same name nested inside one another. Check:

DrawerNavigator > MainTabNavigator > ServiceScreen, DrawerNavigator > MainTabNavigator > ServiceScreen > ServiceScreen

This can cause confusing behavior during navigation. Consider using unique names for each screen instead.
BaseNavigationContainer@http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false&modulesOnly=false&runModule=true&app=org.reactjs.native.example.ywh:147787:28
ThemeProvider@http://localhost:8081/index.bundle?platform=ios&dev=true

原因分析

通过这个层级关系可以看出，写代码的过程中出现名称相同的Screen组件。

• DrawerNavigator > MainTabNavigator > ServiceScreen,
• DrawerNavigator > MainTabNavigator > ServiceScreen > ServiceScreen

虽然是一个警告，但是看着还是很难受的。

解决办法

因为我用Stack把ServiceScreen又嵌套了一层，让它能有header。但是写的时候忘记修改名称了。

const ServiceStackScreen = ({navigation}: any) => {
  return (
    <StackScreen
      navigation={navigation}
      title={'服务'}
      backgroundColor={tabColor3}
      {/*screenName={'ServiceScreen'}修改成screenName={'ServiceStackScreen'}*/}
      screenName={'ServiceStackScreen'}
      component={ServiceScreen}
    />
  );
};

screenName={‘ServiceScreen’}修改成screenName={‘ServiceStackScreen’}
问题解决。

总结

粗心导致的问题。
