Instance Method

usedRect(for:)

Returns the bounding rectangle for the glyphs laid out in the given text container.

Declaration

iOS, Mac Catalyst, tvOS
func usedRect(for container: NSTextContainer) -> CGRect
macOS
func usedRect(for container: NSTextContainer) -> NSRect

Discussion

Returns the text container's currently used area, which determines the size that the view would need to be in order to display all the glyphs that are currently laid out in the container. This causes neither glyph generation nor layout.

Used rectangles are always in container coordinates.
