Token Field
/ NSTokenField · NSTokenField.TokenStyle /
also called token input, recipient field, tag input, pill input
A token field converts recognized pieces of typed text into discrete rounded tokens, like recipients in a mail compose window. Each token represents one value and can be selected, edited, or removed without treating the whole field as plain text. AppKit provides token styling, completions, represented objects, and tokenizing separators through NSTokenField.
Anatomy — every part, named
- 1Token capsule
NSTokenField.TokenStyle“The little rounded bubble around each recipient” is a token capsule.
- 2Selected token
NSTokenField“The whole pill that highlights before I delete it” is the selected token.
Prompt — paste into your agent
Use a native Token Field (NSTokenField) with NSTokenField.TokenStyle so each recognized recipient or tag becomes a separately selectable, removable rounded token inside the editable field. Preserve token completion and keyboard deletion behavior.
