Answer 1

For Ipad down arrow key You can use notification

  [[NSNotificationCenter defaultCenter] addObserver:self
                                                 selector:@selector(keyboardWillHide)
                                                     name:UIKeyboardWillHideNotification
                                                   object:nil];

-(void)keyboardWillHide
{
//call when key board hides
}

Answer 2

You can call the textfield animation method in any one of the following UITextFieldDelegate methods

- (void)textFieldDidEndEditing:(UITextField *)textField {


}

or

- (BOOL)textFieldShouldReturn:(UITextField *)textField {

    return YES;
}

Answer 3

just write your code inside

- (void)textFieldDidEndEditing:(UITextField *)textField {


}

And don't forget to bind textfield delegate and write <UITextfieldDelegate> in .h file

Answer 4

if you want use done button on key board take one view with done button and write this method

-(void)textFieldDidBeginEditing:(UITextField *)textField
{   
    [textField setInputAccessoryView:self.doneView];
}

and then give following action to that done button

-(IBAction)doneButtonPressed:(id)sender
{
    [currentTextField resignFirstResponder];
}
