Customizing the iOS Launch Screen in React Native

Customizing the launch screen of a React Native app can be a bit tricky, especially if you’re encountering a black screen or incorrect image display. This guide will walk you through the steps to properly set up a custom launch screen for your iOS application.

Setting Up Your Launch Screen

To begin with, you’ll need to create appropriate images for the launch screen. These images should be tailored for different device resolutions. Here’s how you can do it:

  • Create images using a template or an automatic generator like TiCons. Ensure you have the following resolutions:
    • 640×960
    • 640×1136
    • 750×1334
    • 1242×2208
    • 2208×1242
  • Place these images inside a folder named LaunchImage.launchimage within your Images.xcassets directory.
  • Include a Contents.json file in the same folder, specifying the image details like orientation and scale.

Configuring in Xcode

Once your images are ready, follow these steps in Xcode:

  1. Open your project in Xcode.
  2. Go to the “General” settings tab.
  3. Under “App Icons and Launch Images,” leave the “Launch Screen File” field empty.
  4. Click “Use Asset Catalog” and migrate your images if prompted.
  5. Select your LaunchImage folder as the “Launch Images Source.”

By following these steps, your React Native application should display your custom launch screens correctly.

Troubleshooting Tips

If you encounter any issues, try the following:

  • Ensure you delete the app from the simulator and perform a clean build.
  • If the launch screen isn’t updating, reset the simulator content.
