Description of Change

This pull request updates the handling of layout logic for the navigation bar's TitleView container in the iOS compatibility renderer. The changes ensure correct display and sizing behavior on iOS 26+ by switching to autoresizing masks, while maintaining compatibility with older iOS versions.

Platform-specific layout adjustments:

In the Container class constructor, for iOS 26+ and Mac Catalyst 26+, the container now uses autoresizing masks (TranslatesAutoresizingMaskIntoConstraints = true and sets AutoresizingMask) instead of constraints to ensure proper TitleView display. For iOS 11+ and Mac Catalyst 11+, constraints are still used.
In the Frame property override, the logic is updated so that for iOS 26+, Mac Catalyst 26+, and pre-iOS 11, autoresizing masks are used and the frame is manually adjusted. This maintains correct sizing and positioning across different platform versions.

Fixes #31671
Fixes #31815

Pull Request Overview

This PR fixes layout issues with navigation bar TitleView containers on iOS 26+ by updating the compatibility renderer to use autoresizing masks instead of constraints. The changes maintain backward compatibility while addressing display problems that occur with the newer iOS version.

Adds iOS 26+ version checks to switch from constraints to autoresizing masks for proper TitleView display
Updates frame adjustment logic to handle both iOS 26+ and pre-iOS 11 scenarios with autoresizing
Maintains existing behavior for iOS 11-25 versions that continue using constraints

Does this affect Shell TitleView as well, or only NavigationPage TitleView?

jsuarezruiz · 2025-10-01T07:29:53Z

src/Controls/src/Core/Compatibility/Handlers/NavigationPage/iOS/NavigationRenderer.cs

 			public Container(View view, UINavigationBar bar) : base(bar.Bounds)
 			{
-				if (OperatingSystem.IsIOSVersionAtLeast(11) || OperatingSystem.IsMacCatalystVersionAtLeast(11))
+				// For iOS 26+, we need to use autoresizing masks instead of constraints to ensure proper TitleView display


Could we include some tests?

@jsuarezruiz We already have many test cases covering the TitleView, so adding a new one would be repetitive. This fix simply ensures that the TitleView is displayed on iOS 26, and the existing tests already validate TitleView behavior. For this reason, I have not added new tests. Also, the failures would occur only when building with iOS 26.

Failures are not related the fix.

in which version this will be included ?

@kdbhalala I'm going to make the assumption it is in https://www.nuget.org/packages/Microsoft.Maui.Controls/9.0.120 that was released yesterday since it is listed fixed under https://github.com/dotnet/maui/releases/tag/9.0.120.
