UIText spell-checks using a lexicon for a given language. You can tell it to ignore specific words when spell-checking a particular document and you can have it learn words, which adds those words to the lexicon. You generally use one instance of
UIText per document, although you can use a single instance to spell-check related pieces of text if you want to share ignored words and other state.
You may also use a text checker to obtain completions for partially entered words, as well as possible replacements for misspelled words, which you then can present to users.
