libGDX iOS / RoboVM Backend

Reference for the iOS backend using RoboVM. Covers launcher setup, RoboVM compilation model, lifecycle, file access, and platform quirks.

Launcher

import org.robovm.apple.foundation.NSAutoreleasePool;
import org.robovm.apple.uikit.UIApplication;

import com.badlogic.gdx.backends.iosrobovm.IOSApplication;
import com.badlogic.gdx.backends.iosrobovm.IOSApplicationConfiguration;

public class IOSLauncher extends IOSApplication.Delegate {
    @Override
    protected IOSApplication createApplication() {
        IOSApplicationConfiguration config = new IOSApplicationConfiguration();
        config.orientationLandscape = true;
        config.orientationPortrait = false;
        config.useAccelerometer = false;   // disable if unused — saves battery
        config.useCompass = false;
        config.preferredFramesPerSecond = 60;  // 0 = max (default)
        config.useHaptics = true;          // REQUIRED for Gdx.input.vibrate() on iOS
        return new IOSApplication(new MyGame(), config);
    }

    public static void main(String[] argv) {
        NSAutoreleasePool pool = new NSAutoreleasePool();
        UIApplication.main(argv, null, IOSLauncher.class);
        pool.close();
    }
}

Backend Variants: Classic vs MetalANGLE

libGDX provides two iOS backend options (both use RoboVM):

Note: Multi-OS Engine (MOE) and gdx-backend-moe are defunct — do NOT recommend them. The only supported iOS backends are RoboVM-based.
