White lines on [searchDisplayController setActive] and "No results" when beginning typing
<p>With help of this:</p>

<pre><code>- (void)viewDidLoad {
 [super viewDidLoad];
 [self.searchDisplayController setActive:YES];
 [self.searchDisplayController.searchBar becomeFirstResponder];
}
</code></pre>

<p>I wanted to show the keyboard in a search when the view loads. It works just fine, but it looks quite ugly (why the white lines in there?):</p>

<p>When I begin to write and remove all the letters it looks like it should from the beginning:</p>

<p>How do I fix this?</p>

<p>And i have another problem. When I begin to type something it instantly shows "No results" even before one presses the "Search" button, how can I change this behaviour?</p>
