How to Disable ImageButton Dimming in MAUI iOS by Setting a Custom Button Type?

Below is one solution that lets you remove the default “dimming” behavior on iOS by customizing the underlying UIButton. In iOS the ImageButton is rendered as a UIButton, so you can use a custom handler that sets its UIButton property AdjustsImageWhenHighlighted (or even configures the UIButton type) so that it behaves like a custom button.

For example, you can add a custom handler for ImageButton in your MauiProgram.cs as follows:

CSHARPCopied
using Microsoft.Maui.Handlers;
#if IOS
using UIKit;
#endif

public static class MauiProgram
{
    public static MauiApp CreateMauiApp()
    {
        var builder = MauiApp.CreateBuilder();
        builder
            .UseMauiApp<App>()
            // Add your handler changes here...
#if IOS
            .ConfigureMauiHandlers(handlers =>
            {
                // Append custom mapping for ImageButton on iOS
                handlers.AddHandler(typeof(ImageButton), typeof(CustomImageButtonHandler));
            });
#endif
        return builder.Build();
    }
}

#if IOS
public class CustomImageButtonHandler : ImageButtonHandler
{
    protected override UIButton CreatePlatformView()
    {
        // Create the UIButton that MAUI would normally create
        var button = base.CreatePlatformView();
        // Disable the automatic dimming on press by turning off the highlighted adjustment.
        button.AdjustsImageWhenHighlighted = false;
        return button;
    }
}
#endif

How It Works

• Custom Handler: We are subclassing the default ImageButtonHandler on iOS in order to customize the creation of the UIButton.
• UIButton Configuration: By setting AdjustsImageWhenHighlighted to false, the platform button stops applying the default dimming (or highlighting) animation when pressed—this is equivalent to using a "custom" button type in iOS Xcode.
• Registration: The custom handler is registered via ConfigureMauiHandlers when building the MAUI app.

Using this approach, your ImageButton in XAML will only display your provided images (for normal and pressed states) without the extra dimming effect. This mirrors the behavior you’d get by configuring a UIButton as “Custom” in Xcode.
