[iOS] Fixed the flyout icon and content page disappeared when focus on the shell search handler

[NanthiniMahalingam]

Issue Details

• When the search controller has an empty item source and is focused on the Shell search handler, the flyout icon and content page title disappear with no option to make them visible again.

Root Cause

• The ShowsCancelButton property of the Shell's UISearchController search bar is set to false. As a result, when the search controller is focused, the cancel button does not appear, preventing the flyout icon and content page title from being visible when the search controller has an empty item source.

Description of Changes

• Setting ShowsCancelButton to false is no longer necessary, as this behavior is now handled by the automaticallyShowsCancelButton property in UISearchBar.
• The cancel button ensures that the flyout icon and content page title return to their normal visibility after focusing and unfocusing. When clicking the cancel button, the flyout icon and content page title are now correctly displayed, when the search controller has an empty item source.

Issues Fixed

Fixes #22060

Validated the behaviour in the following platforms

• Android
• Windows
• iOS
• Mac

• The removal of setting ShowsCancelButton to false is correct based on the new behavior. Please ensure that automaticallyShowsCancelButton is consistently handling the cancel button appearance across all scenarios on iOS.

_uiSearchBar.ShowsCancelButton = false;

Is fine, although it would be nice to run the test on all the platforms. You'd need queries for each case, though.

[NanthiniMahalingam]

Hi @jsuarezruiz
Yes, I have added queries for each platform and included test cases for all platforms.

Issue: #22060 - Flyout icon and content page disappeared when focus on the shell search handler
PR: #28474 - [iOS] Fixed the flyout icon and content page disappeared when focus on the shell search handler
Platforms Affected: iOS
Files Changed: 2 implementation, 2 test, 4 snapshot

Key Findings

• The PR removes an explicit UISearchBar.ShowsCancelButton = false assignment from SearchHandlerAppearanceTracker on iOS and adds a Shell issue page plus screenshot UITest coverage for issue #22060.
• Review discussion shows the PR previously failed because the new EnterTextInShellSearchHandler helper was added without a matching namespace import; the current diff includes the helper implementation in UITest.Appium/HelperExtensions.cs.
• The UITest method currently carries two [Category] attributes (Shell and SearchBar), which violates the repository UI test guidance requiring exactly one category per test.
• The test file uses inline #if IOS inside the test method to tap the Cancel button, which also conflicts with the repository UI test guidance to hide platform-specific behavior behind helpers/extensions.
• The PR description claims validation on Android, Windows, iOS, and Mac, but the functional fix itself is iOS-specific; the extra platforms appear relevant only because the shared UITest helper/test compile and snapshot assets were updated.

Edge Cases / Review Notes

• The bug specifically depends on focusing a Shell search handler with an empty item source, so gate verification needs to prove the added UITest actually fails without the iOS fix and passes with it.
• Because the test uses shared test infrastructure and snapshots on all platforms, build-only regressions outside iOS are still relevant even though the runtime bug is iOS-specific.

Issue: #22060 - [iOS] Flyout button and title disappears after focusing shell search
PR: #28474 - [iOS] Fixed the flyout icon and content page disappeared when focus on the shell search handler
Platforms Affected: iOS (runtime bug); test snapshots also added for Android, Windows, Mac
Files Changed: 2 implementation (fix + helper), 2 test, 4 snapshot

Key Findings

• The PR removes a single line _uiSearchBar.ShowsCancelButton = false from SearchHandlerAppearanceTracker.cs on iOS, which prevented the native cancel button from appearing after focusing the Shell search, leaving the flyout icon and title hidden.
• A new EnterTextInShellSearchHandler extension method was added to HelperExtensions.cs.
• 🚨 CRITICAL REGRESSION: GetDisplayDensity() extension method (and its helpers GetAndroidDisplayDensity, GetIOSDisplayDensity) was REMOVED from HelperExtensions.cs as a side-effect of adding EnterTextInShellSearchHandler. This breaks Issue28986_SafeAreaBorderOrientation.cs which calls App.GetDisplayDensity() on line 21 — this will cause a build error in the test project.
• The new UITest Issue22060.cs carries two [Category] attributes (Shell and SearchBar), violating the repo convention of exactly one category per test.
• The test method contains an inline #if IOS directive to tap "Cancel" on iOS, violating the repo convention that platform-specific logic should be hidden behind extension methods.
• The HostApp page Issue22060Shell extends Shell directly rather than the TestShell helper base class.
• Prior agent review (MauiBot, commit 81d2fe8) gave a comprehensive analysis with the same code-quality concerns.

Edge Cases / Review Notes

• The single-line removal is the minimal correct fix; native automaticallyShowsCancelButton on UISearchBar handles cancel visibility automatically.
• The GetDisplayDensity deletion appears unintentional — likely a copy/paste error where the author replaced the method block instead of inserting alongside it.

Gate Result PASSED:

Platform: ios
Mode: Full Verification

• Tests FAIL without fix:
• Tests PASS with fix:

Notes

• Verification was run via an isolated task agent using the verify-tests-fail-without-fix skill on iOS with TestFilter: Issue22060.
• The task agent reported successful two-way verification: the new test failed without the PR fix and passed with the PR fix.
• The task agent also made local verification edits in Issue22060.cs (removing a duplicate [Category]) and in unrelated Issue28986_SafeAreaBorderOrientation.cs to work around a test compilation blocker. Those edits were not part of the PR under review and are not relied on as part of the functional iOS fix assessment.
• The shared UI test still contains inline #if IOS platform logic, which is contrary to repository UI test guidance, but it did not prevent the gate from validating the regression.

Root Cause of Gate Failure

The "with fix" run failed due to build errors in the test project, not a test runtime failure. The app built successfully, but the iOS test project (Controls.TestCases.iOS.Tests.csproj) failed to compile:

1. error CS1061 — Issue28986_SafeAreaBorderOrientation.cs:21 calls App.GetDisplayDensity(), which was accidentally deleted from HelperExtensions.cs as a side-effect of adding EnterTextInShellSearchHandler.

2. error MAUI0002 — Issue22060.cs:18 has two [Category] attributes (Shell + SearchBar), violating the repo's MAUI analyzer rule requiring exactly one category per test.

Important: The iOS fix itself (removing ShowsCancelButton = false) is functionally correct — the test correctly FAILED without the fix, proving the test detects the bug. The gate failure is caused by introduced regressions in the PR's test/helper code, not the iOS runtime fix.
