iOS How to dismiss UIAlertView with one tap anywhere?

Question

I want to dismiss UIAlertView anywhere outside it with one tap. I want to show a UIAlertView without any button.

I have standard UIAlertView codes here, but I need

Answer 1

After showing UIAlertView add to your view controller (or even window) new empty UIView with full screen size. Attach to this wiew UITapGestureRecognizer

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
[view addGestureRecognizer:singleTap];
[singleTap release];

Now in handleSingleTap method you can dismiss UIAlertView and remove this view from window

-(void)handleSingleTap:(UITapGestureRecognizer *)sender{
    [myAlert dismissWithClickedButtonIndex:0 animated:YES];
    [view removeFromSuperView];
}
