iPhone: UIAlertView overlap
<p>Every 10 min I synchronize my app with server, and when something wrong with server, I show UIAlertView. </p>

<pre><code>    NSString *alertTitle = @"Sync failed";
    NSString *alertMessage = @"Something wrong with server"

UIAlertView *alertView = [[UIAlertView alloc]
    initWithTitle:alertTitle
    message:alertMessage
    delegate:nil
    cancelButtonTitle:NSLocalizedString(@"OK", @"OK button title")
    otherButtonTitles:nil];
[alertView show];
[alertView release];
</code></pre>

<p>If to shoot down server and do not touch phone, in hour there will be 6 Alert Dialogs, and I supposed to close 6 AlertDialogs. How to fix that ? Can AlertView check if its already shown to user or something like that ? Thanks...</p>
