请使用此代码进行导航

import {
  createStackNavigator,
  createSwitchNavigator,
  createAppContainer,
} from 'react-navigation';
// Auth screens
import Login from './Screen/Login'
import Signup from './Screen/Signup'
// Auth stacks
const AuthStackLogin = createStackNavigator({
  Login,
  Signup,
},{ 
  headerMode: 'none' 
}
);
export default createAppContainer(createSwitchNavigator(
  {
    AuthStackLogin: {
      screen: AuthStackLogin
    },
  },
  {
    initialRouteName: 'AuthStackLogin'
  }
));
