react-native-launch-image

Only iOS was supported. (for native iOS launch image)

For both iOS&Android support, maybe you can use rn-splash-screen, which provides a extra view to contain launch image.

Notice: You should not keep launch image more than 5 seconds, which may cause your app got killed by iOS. To do long-time work(like http request, which may fail or tooks long), you should first render a react native page, then hide launch image before work, or set a timeout, hide launch image even if request is still waiting.

Getting started

$ npm install react-native-launch-image --save

Mostly automatic installation

$ react-native link react-native-launch-image

Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-launch-image and add RNLaunchImage.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNLaunchImage.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Usage

iOS

You should add following code to AppDelegate.m for keeping launch image:

 
#import "AppDelegate.h"
 
#import "RCTRootView.h"
#import "RNLaunchImage.h"  // <-- Add this line.
 
@implementation AppDelegate
 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // ...other code
    
    [RNLaunchImage wait];   // <-- Add this line. This line MUST be the last line of this method.
    return YES;
}
 
@end
 

Javascript

Use RNLaunchImage.hide() to hide launch image manually.

import * as launchImage from 'react-native-launch-image';
 
class App extends React.Component {
    async componentDidMount(){
        // do anything while launch image keeps, use await to wait for an async task.
        launchImage.hide();
    }
}
