I can\'t believe that this question hasn\'t been asked yet, but I have been unable to find it so that is my assumption.
I have created custom UITableViewCel
UITableViewCel
you have to invoke [textView reloadInputViews]; after setting the return key type to update the keyboard return key appearance immediately.
[textView reloadInputViews];
DO IT AS FLLOW:
textView.returnKeyType = UIReturnKeyDone; [textView reloadInputViews];
