Discussion 議論

An Accessibility Rotor is a shortcut for Accessibility users to quickly navigate to specific elements of the user interface, and optionally specific ranges of text within those elements.

In the following example, a Message application adds a Rotor allowing the user to navigate through all the ranges of text containing headings.


extension Message {
    // Ranges of special areas in the `content` text. Calculated when
    // `content` is set and then cached so that we don't have to
    // re-compute them.
    var headingRanges: [Range<String.Index>]
}


struct MessageContentView: View {
    TextEditor(.constant(message.content))
        .accessibilityRotor(
            .heading,
            textRanges: message.headingRanges
        )
}
