Check user preferences for spell checker and autocorrect

I would like to make a switch for on / off AutoCorrect

and CheckSpelling

function in UITextView

.

As far as I know, when the user has disabled CheckSpelling

in iOS (Settings> General> Keyboard> Spell Checker) there is no way to enable it programmatically. Apple says it spellCheckingType

overrides iPhone settings. But as it turns out, this is not the case.

It works only when the user has AutoCorrect

and CheckSpelling

, they can be disabled programmatically, unfortunately, on the contrary, it does not work.

So, is there a way to check if the user has disabled these properties in their iOS settings? Then I could give some kind of feedback to the user, how can he return them back.
