Anyone know how can I know this dimmensions ?

Answer 1

You can do this by changing UITableView bottom Constraint.

Pin your UITableView bottom to superView.Then register for UIKeyboardWillShowNotification / UIKeyboardWillHideNotification and get from NSNotification object keyboard frame and change bottom constraint constant, like this:

- (void)keyboardWillShow:(NSNotification *)notification {
    CGRect keyboardRect = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
    self.tableViewBottomConstraint.constant = CGRectGetHeight(keyboardRect);
   [self.view layoutIfNeeded];
}
