Hiding the status bar with React Native

For Hidden:

StatusBar.setHidden(true, 'none');

For Show:

StatusBar.setHidden(false, 'slide');

From version 0.?? to current (0.55 / June 2018)

<StatusBar hidden />

Remember to first import the StatusBar component as per the other answers here

If your reason for hiding it is to prevent your components from overlapping it, you might prefer to just use SafeAreaView as follows:

<SafeAreaView style={{flex: 1, backgroundColor: '#fff'}}>
  <View style={{flex: 1}}>
    <Text>Hello World!</Text>
  </View>
</SafeAreaView>

It should be the parent component of a screen and can optionally use a backgroundColor to match the color of your screen. Make sure to set a flex attribute. Your components will now just take up any area not being used by the status bar. This is especially useful in getting around the 'notch' issue with some of the newer phones.

SafeAreaView is a component of react-native so you will need to make sure you add it to your imports:

import { SafeAreaView, Text, View } from 'react-native';

to make it transparent on android you can do this

<StatusBar  backgroundColor={'#ffffff00'} />

{Platform.OS === 'ios' && <StatusBar barStyle="light-content" />} 

also <StatusBar hidden /> is hidden it but you may see a margin on top

It hasn't worked doesn't matter what you have tried?

Maybe there is another <StatusBar hidden="false"> in your code. And it is deeper than your definition. This will replace your previous hidden="true" setting.

<View>
  <StatusBar hidden={true} /> // this will be replaced by the deeper StatusBar tag
  
  <View>
    <StatusBar hidden={false} /> // remove this or put your `hidden="true"` here
  </View>
</View>
