I would like to know the location开发者_如何学Python on disk where the learned words are stored for the spellchecker and how to reset them.

In addition it would be nice to know where are the spellcheck dictionaries located.

I found on a forum that the location should be:

/private/var/mobile/Library/Keyboard/dynamic-text.dat - for English /private/var/mobile/Library/Keyboard/xx_XX-dynamic-text.dat - for other languages, where xx_XX is the ISO language code.

To remove these dictionaries you can go to Settings> General> Reset > Reset Keyboard Settings.

/System/Library/LinguisticData/...
