Custom actions for hidden interactions

9 Dec 2022

If you have interactions that are hidden or require complex gestures to be performed or that may conflict with VoiceOver, you need to provide alternative ways of executing these actions. Custom actions can help a lot of times, but not always.

Calendar of Advent of iOS Accessibility. Day 9. Hidden actions not being accessible. Find alternative ways of actioning hidden interactions or that require complex gestures or gestures that conflict with VoiceOver's. Two examples. The first one is swiping left in a table view cell to unveil a delete option. That could be fixed by adding delete as a custom action. Second example is a bottom sheet menu with a grid of options. You need to swipe down to dismiss it. You'd probably need to implement the escape gesture for VoiceOver and it would be a good idea to add a close button anyway.

Some of you have asked me how you can support what I do. This would really help, and would be hugely appreciated:

Find these posts useful? Share them at work, on social media, or with anyone that might find them interesting. Let's spread the word!
Check out any of my apps or games: Xarra!, RetroRapid!, or Mestre!.
- A download and a review go a long way. They're free by default. On the App Store, ratings and reviews really help more people discover them.
- Finding any of them useful? If so, and if you can afford it, purchasing lifetime access to all features or subscribing lets me buy the coffee that keeps me caffeinated. Caffeine keeps me going to maintain the apps, bring in new features that I hope you'll love, and keep writing.

Override labels for NSTextAttachment icons

It is possible to embed icons within text using NSTextAttachment and NSAttributedString. If you do, please remember to override the accessibility label, otherwise VoiceOver will announce it as "Attachment.png File". Example code in the image: ```swift let magnifyingGlassIcon = UIImage(systemName: "magnifyingglass")! let searchButton = UIButton() let searchTutorialLabel = UILabel() searchButton.accessibilityLabel = "search" let textAttachment = NSTextAttachment(image: magnifyingGlassIcon) let string = "Select the button to find elements in the list" let attributedString = NSMutableAttributedString(string: string) let attributedStringIcon = NSAttributedString(attachment: textAttachment) let iconPlaceholderRange = attributedString.string.range(of: "")! let iconRange = NSRange(iconPlaceholderRange, in: attributedString.string) attributedString.replaceCharacters(in: iconRange, with: attributedStringIcon) searchTutorialLabel.attributedText = attributedString searchTutorialLabel.accessibilityLabel = string.replacingCharacters(in: iconPlaceholderRange, with: searchButton.accessibilityLabel!) ```

Double-pinch quick actions on Watch

If your watch app has good VoiceOver support, chances are you'll also have good Assistive Touch support. But an improvement you can make is to implement a quick action (triggered with a double pinch) when there is a main action you can perform.
