Introduction to React Native Splash Screen
Splash Screen can be defined as a graphical control element that consists of a window that consists of the current version of the software, a logo, and an image. A splash screen is majorly seen when a particular program or a game is launching and it is even used when an application or website need essential information before it get started. A splash page can be said as an introduction on an application or a website. The Splash Screen automatically gets hidden after few seconds from the display screen and will appear again when the application will start again. The below images shows where can find splash screens in day to day life. These are the examples of Google Play Music, Google Maps, Gmail, Google Photos.

Below are still learn to create Splash Screen with examples:
1. Simple logo image in iOS platform
Code:
import React, { Component } from 'react';
import { StyleSheet, Platform, TouchableOpacity, Image, View, Text, Alert
} from 'react-native';
export default class Myapp extends Component<{}>
{
constructor(){ super(); this.state={ isVisible : true,
}
}
Hide_Splash_Screen=()=>{ this.setState({
isVisible : false
});
}
componentDidMount(){ var that = this;
setTimeout(function(){ that.Hide_Splash_Screen();
}, 5000);
}
render()
{
let Splash_Screen = (
<View style={styles.SplashScreen_RootView}>
<View style={styles.SplashScreen_ChildView}>
<Image source={{uri:'https://static.javatpoint.com/tutorial/react- native/images/react-native-tutorial.png'}}
style={{width:'100%', height: '100%', resizeMode:
'contain'}} />
</View>
</View> )
return(
<View style = { styles.MainContainer }>
<Text style={{textAlign: 'center',width: '100%'
,backgroundColor: '#fc8bef'}}> Example of Simple Splash Screen</Text>
{
(this.state.isVisible === true) ? Splash_Screen : null
}
</View>
);
}
}
const styles = StyleSheet.create(
{
MainContainer:
{
flex: 1,
justifyContent: 'center',
alignItems: 'center',
paddingTop: ( Platform.OS === 'ios' ) ? 20 : 0
},
SplashScreen_RootView:
{
justifyContent: 'center',
flex:1,
margin: 10,
position: 'absolute', width: '100%',
height: '100%',
},
SplashScreen_ChildView:
{
justifyContent: 'center', alignItems: 'center', backgroundColor: '#fcf52b', flex:1,
},
});Output:
Explanation: Here in Image 1 and Image 2 we can see the output of the above code and how Splash Screen works in React Native. The React Native Logo splashes a new page. This is the most simple example to understand Splash Screen, i.e. text appears.
2. Animated Splash Screen
Code:
import React, { Component } from 'react';
import {View, Image, Text } from 'react-native';
export default class App extends Component { constructor() {
super(); this.state = {
animating: false, align: 'center', alignsecond: false,
};
setTimeout( () =>
this.setState({ align: 'flex-start' }, function() { this.setState({
alignsecond: true,
});
}), 3000
);
}
render() { return (
<View
style={{ flex: 1,
alignItems: 'center', flexDirection: 'row', justifyContent: this.state.align, marginHorizontal: 40,
}}>
<Image
source={{ uri:
'https://raw.githubusercontent.com/AboutReact/sampleresource/master/react_l ogo.png',
}}
style={{ width: 100, height: 100 }}
/>
{!this.state.alignsecond ? null : (
<View style={{ margin: 10 }}>
<Text
style={{ color: '#092c96', fontSize: 25, fontWeight: 'bold'
}}>
Welcome to React Native Mobile Application
</Text>
</View>
)}
</View>
);
}
}Output:
Explanation: Here in Image 1 and Image 2 we can see a slight animation in which the logo comes first and then comes the text.
3. Splash screen of app uploading
Code:
import React from 'react';
import { View, Text } from 'react-native';
class SplashScreen extends React.Component { performTimeConsumingTask = async() => {
return new Promise((resolve) => setTimeout(
() => { resolve('result') }, 2000
)
)
}
async componentDidMount() {
const data = await this.performTimeConsumingTask();
if (data !== null) { this.props.navigation.navigate('App');
}
}
render() { return (
<View style={styles.viewStyles}>
<Text style={styles.textStyles}> Welcome to the application
</Text>
</View>
);
}
}
const styles = { viewStyles: {
flex: 1,
alignItems: 'center', justifyContent: 'center', backgroundColor: '#79ff26'
},
textStyles: {
color: '#ff4824', fontSize: 50, fontWeight: 'italic'
}
}
export default SplashScreen;Outputs:
Explanation: All the 7 four images below shows how splash screen arrives and disappear in the particular mobile application.

Code:
import React, { Component } from 'react';
import { StyleSheet, Platform, TouchableOpacity, Image, View, Text, Alert
} from 'react-native';
export default class Myapp extends Component<{}>
{
constructor(){ super(); this.state={ isVisible : true,
}
}
Hide_Splash_Screen=()=>{
this.setState({ isVisible : false
});
}
componentDidMount(){ var that = this;
setTimeout(function(){ that.Hide_Splash_Screen();
}, 5000);
}
render()
{
let Splash_Screen = (
<View style={styles.SplashScreen_RootView}>
<View style={styles.SplashScreen_ChildView}>
<Image source={{uri:'https://raw.githubusercontent.com/AboutReact/sampleresource/m aster/react_logo.png'}}
style={{width:'100%', height: '100%', resizeMode:

</View> )
return(
<View style = { styles.MainContainer }>
<Text style={{textAlign: 'center',width: '100%'
,backgroundColor: '#36fffc'}}> The screen came earlier shows a Splash Screen</Text>
{
(this.state.isVisible === true) ? Splash_Screen : null
}
</View>
);
}
}
const styles = StyleSheet.create(
{
MainContainer:
{
flex: 1,
justifyContent: 'center', alignItems: 'center',
paddingTop: ( Platform.OS === 'android' ) ? 10 : 0
},
SplashScreen_RootView:
{
justifyContent: 'center', flex:1,
