Hide UISearchDisplayController of UITableView initially ( iOS SDK )?

Question

How can I hide UISearchDisplayController of UITableView initially ? I just want user to scroll up to see the UISearchBar.

UPDATE: I am thinking of scrolling the UITableView 40px lower, so that the UISearchBar can be "hidden" from user.

My solution is in viewWillAppear:animted :

[my_table_view setContentOffset:CGPointMake(0, searchController.searchBar.bounds.size.height)];

UPDATE we should obtain the height of UISearchBar instead of using fixed values.

height of SearchBar is 44 points – Tankista Mar 21 '13 at 11:51

Don't use constants like this. Use `searchController.searchBar.bounds.height` instead. The height may change in future iOS versions and that will break your code, but not this one. – Charlie Monroe Mar 25 '16 at 16:35

`searchController.searchBar.bounds.height` property doesn't exist. It should be `searchController.searchBar.bounds.size.height` – Giorgio Mar 16 '17 at 08:23
You're right. corrected. – Raptor Mar 16 '17 at 09:09

Here is how I hide search bar in view will appear. This snipped will make sure that search bar is initially hidden only at the very first time of view will appear call.

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    //hide search bar
    if (_searchBarRevealed == NO) {
        self.tableView.contentOffset = CGPointMake(0, 44);
        _searchBarRevealed = YES;
    }
}
