Txt Nstextstorage

Quality score: 70/100 · Category: Dev Tools · Sub-category: tools-misc

Subclass and reason about NSTextStorage, NSTextContentStorage, and NSTextContentManager. Covers the editing lifecycle (beginEditing / edited / processEditing / fixAttributes), the four required primitives for an NSTextStorage subclass, NSTextStorageDelegate hooks (willProcessEditing vs didProcessEditing), edit batching, the TextKit 2 performEditingTransaction wrapper, NSTextContentStorageDelegate for display-only paragraph rewriting, and when to subclass NSTextContentManager directly for non-attributed-string backing stores. Use when implementing a custom backing store (rope, piece table, gap buffer), wiring syntax highlighting through delegate callbacks, debugging missing edited() calls, or routing edits through the TextKit 2 transaction model. Do NOT use for symptom-driven debugging — see txt-textkit-debug.
