Answer 1

Mmmm...quick answer. Not pretty but surely works

    #pragma mark UISearchBarDelegate

// Displays a view to simulate the lose of focus
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar {

  searchBar.showsCancelButton = NO;
  searchBar.autocorrectionType = UITextAutocorrectionTypeNo;

  UIButton *view1 = [[UIButton alloc] init];
  view1.frame = CGRectMake(0, 0, 320, MAX(480, self.tableView.contentSize.height));
  view1.alpha = 0.6;
  view1.tag = 2000;
  view1.backgroundColor = [UIColor blackColor];
  [view1  addTarget:self
             action:@selector(removeView)
   forControlEvents:UIControlEventTouchUpInside];
  [self.tableView setScrollEnabled:NO];

  [self.tableView addSubview:view1];
  [view1 release];
}

/**
 *  Pop the view and the keyboard
 */
- (void)removeView {
  UIView *v = [self.tableView viewWithTag:2000];
  v.hidden = YES;
  [v removeFromSuperview];
  [self.tableView setScrollEnabled:YES];
  [self.searchBar resignFirstResponder];
}

That view is showed when you're writing, so I guess you should use it at searchBarTextDidBeginEditing. If I'm wrong, use it when you start searching or whatever.
