This page describes how to use the macOS Accessibility APIsto build apps according to theaccessibility checklist.Refer to the Android accessibilityand iOS accessibility pages forother platform APIs.

• Dark Mode Let your content take center screen. Dark Mode transforms the desktop and built-in apps with a dark color scheme that helps you focus on your work. 1 The fine points of your content take center screen as toolbars and menus recede into the background. Light text against darker backdrops in Mail, Safari Reader, Calendar, and more makes everything easier to read in low lighting conditions.
• Accessibility Keyboard. Type what you see. You can navigate macOS with minimal use of a physical keyboard. The Accessibility Keyboard is fully customizable and gives users advanced typing and navigation capabilities. And it includes toolbar support, as well as improved typing, autocapitalization, and word suggestions.

To understand how the accessibility APIs work in macOS (formerly called OS X), first reviewthe OS X accessibility model.

Describing UI elements

May 12, 2020  Recently, a new bug that is bothering iOS people is they can't find app in Settings. And so, today we will be discussing best ways to solve 'apps not showing in settings in iPhone' issue. Solution 1: Quit the Settings App. The first solution to solve 'apps not showing in settings on iPhone' issue is quitting the Settings app entirely.

AppKit uses the NSAccessibility protocol to expose APIs that helpmake the user interface accessible. This includes a default behaviorthat attempts to set meaningful values for accessibility properties, suchas setting a button's AccessibilityLabel. The labelis typically a single word or short phrase describing the control or view.

Storyboard Files

Xamarin.Mac uses the Xcode Interface Builder to edit storyboard files.Accessibility information can be edited in the Identity inspectorwhen a control is selected on the design surface (as shown in the screenshot below):

Code

Xamarin.Mac does not currently expose as AccessibilityLabel setter. Addthe following helper method to set the accessibility label:

This method can then be used in code as shown:

The AccessibilityHelp property is for an explanation of what the controlor view does, and should only be added when the label may not provide sufficientinformation. The help text should still be kept as short as possible, forexample 'Deletes the document'.

Some user interface elements are not relevant for accessible access (such asa label next to an input that has its own accessibility label and help).In these cases, set AccessibilityElement = false so that these controls orviews will be skipped by screen readers or other accessibility tools.

Apple provides accessibility guidelinesthat explains the best practices for accessibility labels and help text.

Custom controls

Refer to Apple's guidelines for accessible custom controlsfor details on the additional steps required.

Testing accessibility

macOS provides an Accessibility Inspector that helps testaccessibility functionality. The inspector is included with Xcode.

Accessibility Settings Mac

The first time it is launched, the Accessibility Inspector willrequire permission to control the computer via accessibility:

Once enabled, the inspector appears as a floating window that can be moved aroundthe screen. The screenshot below shows the inspector running next to a sample Mac app. As the cursoris moved over the window, the inspector displays all the accessible propertiesof each control:

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.

Did you download the apps directly to your iPad? Have you transferred those purchases from the iPad to the Macs? If not, then no they will not be showing in the Apps library in iTunes on the Macs.

Otherwise you can set up iTunes on your Macs to automatically download the content that you buy directly on your iPad, when the Macs are online and you open the iTunes app. Open iTunes on your Mac, sign into your Apple ID for iTunes and go to Prefences/Store. In Automatic Downloads choose the content that you want iTunes to automatically download; music, apps and books. Then check the option Always check for available downloads.

You can set up the iPad to also automatically download content that you buy with iTunes on your Macs in Settings/Store.
