i'm trying create view similar iphone's mail application. in mail app, in compose mode, after entering to, cc , subject, started entering text. number of lines increases, view scroll (still keeping keyboard) , user pointed last line of text.

how can achieve such view. how can done.

you potentially use uitextviewdelegate , implement (void)textviewdidchange:(uitextview *)textview

then in implementation call [textview bounds] , obtain height... shift view accordingly.

seems there should better way though... hope gives start least
