How to prevent layout from overlapping with iOS status bar

Now you can use SafeAreaView which is included in React Navigation:

<SafeAreaView>
    ... your content ...
</SafeAreaView>

There is a very simple way to fix this. Make a component.

You can create a StatusBar component and call it first after the first view wrapper in your parent components.

Here is the code for the one I use:

'use strict'
import React, {Component} from 'react';
import {View, Text, StyleSheet, Platform} from 'react-native';

class StatusBarBackground extends Component{
  render(){
    return(
      <View style={[styles.statusBarBackground, this.props.style || {}]}> //This part is just so you can change the color of the status bar from the parents by passing it as a prop
      </View>
    );
  }
}

const styles = StyleSheet.create({
  statusBarBackground: {
    height: (Platform.OS === 'ios') ? 18 : 0, //this is just to test if the platform is iOS to give it a height of 18, else, no height (Android apps have their own status bar)
    backgroundColor: "white",
  }

})

module.exports= StatusBarBackground

After doing this and exporting it to your main component, call it like this:

import StatusBarBackground from './YourPath/StatusBarBackground'

export default class MyScene extends Component {
  render(){
    return(
      <View>
        <StatusBarBackground style={{backgroundColor:'midnightblue'}}/>
      </View>
    )
  }
}
