ipad onscreen keyboard origin

I want to know what is the exact origin of onscreen keyboard on ipad. Does it dynamically change depending on the language we use, or not?

I try to get this value to make a frame for UITextview in my app.

Is it a difference in origin or behavior, if I use a wireless external keyboard or dock ex开发者_StackOverflow社区ternal keyboard??

This is my app screenshot when i use the external keyboard:

And this is when I use the onscreen keyboard:

Yes, the height of the keyboard is different depending on what language you use. As far as retrieving the height goes, I would suggest checking out: UIKeyboardBoundsUserInfoKey is deprecated, what to use instead?

Not sure if this question should be considered a duplicate.
