UITextChecker is what dictionary?

Question

Does anybody know what dictionary UITextChecker pulls from? I use it to verify that a word is in fact a valid word in an app. I have some questions from users about why specific words are available in other games (Boggle/Scrabble) but not in mine.

Examples: ai, qi, qat, xu, ae, tae, ait, ain, lav, aa, shh, za

I checked against /usr/share/dict/words and none of these words are in Websters Second International, so maybe UITextChecker uses this same source? They do show up in other dictionaries online (but this is really besides the point of the post).

Thanks for any insight!

Answer 1

UITextChecker may be using the same dictionary that UIReferenceLibraryViewController uses. In which case, you could use something like [UIReferenceLibraryViewController dictionaryHasDefinitionForTerm: @"term"] and if it returns true the word exists. I'm not sure how complete the built in dictionary is however.
