delete . while seraching in serach bar for iphone
<p>after getting result from my search in search bar i am putting a "." in that search bar text field as i need that</p>

<p>but i want to omit that in this function  so that next time i get a empty serachbar for fresh serach</p>

<pre><code>- (void) searchBarTextDidBeginEditing:(UISearchBar *)theSearchBar {
    //searchBar.text = @"\n";
}
</code></pre>
