TTTAttributedLabel/TTTAttributedLabel
TTTAttributedLabel
TTTAttributedLabel is a rich text label for iOS applications that serves as an extension to UIKit typography. It provides a replacement for standard system labels, enabling advanced layout control and the rendering of attributed strings with custom paragraph styling, line spacing, and vertical alignment.
The component is distinguished by its ability to generate interactive links within text blocks, using either custom ranges or automated data-detector pattern matching for phone numbers and addresses. It includes a specialized accessibility system that exposes these individual links as selectable elements for screen reader and voice-over users.
The project covers broad capabilities in rich text rendering, coordinate-based hit testing for precise link activation, and the management of virtual accessibility element trees.
