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 email addresses.


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 emailAddressRanges: [Range<String.Index>]
}


struct MessageContentView: View {
    TextEditor(.constant(message.content))
        .accessibilityRotor("Email Addresses",
            textRanges: message.emailAddressRanges)
}
