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
)
}
