I write a piece of code to ‘do something->show alert1->do something->show alert2’.

     //do something     UIAlertView *alert = [[UIAlertView alloc]                            initWithTitle:@'Alert 1'                            message:nil                            delegate:nil                            cancelButtonTitle:@'OK'                            otherButtonTitles:nil];     [alert show];     [alert release];     //do something       UIAlertView *alert2 = [[UIAlertView alloc]                             initWithTitle:@'Alert 2'                             message:nil                             delegate:nil                             cancelButtonTitle:@'OK'                             otherButtonTitles:nil];     [alert2 show];     [alert2 release];

And suddenly a strange thing happened to multiple AlertViews: It shows ‘Alert 1’->’Alert 2′(Press ‘OK’)->’Alert 1′. Why ‘Alert 1’ shows again? I haven’t written any delegate method yet. Maybe a bug?(Thanks to cobbal, alert1 is still there when alert2 appears.)

I find -(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex works well. Is the delegate method a common way to show multiple alertViews?

  1. I would guess that alert 1 is shown and then covered by alert 2 since show isn’t modal. When alert 2 is closed, alert 1 is still open.

    To your second question, alertView:didDismissWithButtonIndex: may work better, but I haven’t actually tested that.
