Txt Textkit1

Quality score: 70/100 · Category: Content · Sub-category: content-misc

Reference for TextKit 1 — NSTextStorage, NSLayoutManager, NSTextContainer. Covers the storage / layout manager / container triad, glyph generation and queries, line-fragment geometry, multi-container layout, exclusion paths, temporary attributes, non-contiguous layout, and NSLayoutManager / NSTextStorage delegate hooks. Use when working with code that already uses NSLayoutManager, when an editor was created with UITextView(usingTextLayoutManager: false), when maintaining legacy TextKit 1 code, or when Apple's apps (Pages, Xcode, Notes) and other TextKit 1 codebases need glyph-level access. Do NOT use for the picker decision between TK1 and TK2 — see txt-textkit-choice. Do NOT use for symptom-driven debugging — see txt-textkit-debug.
