Answer 1

Finally I have my answer which want to share with every one

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
        [textField resignFirstResponder];
        NSTimer *theTimer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(keyboardWasShown:) userInfo:nil repeats:NO];
}

- (void)keyboardWasShown:(NSNotification *)notification
{
    [self.searchDisplayController.searchBar becomeFirstResponder];
    self.searchDisplayController.searchBar.hidden = FALSE;
    CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
    CGRect aRect = self.view.frame;
    aRect.size.height -= keyboardSize.height;
}

This line is going to create problems:

[textField resignFirstResponder];

WHy is it there. If you want to show the keyboard. You should not be calling this at this point. That will Dismiss or Hide the keyboard?

Well where do you call [textField becomeFirstResponder] ?

You can also use this UISearchBar, rather than try to write your own.
