Question

Can I remove a subview with cancelButtonTitle of a UIAlert? Because I write this:

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Done!" 
                                                    message:[@"It's all ok!"]
                                                   delegate:nil 
                                          cancelButtonTitle:@"OK" 
                                          otherButtonTitles:nil];

[self dismissModalViewControllerAnimated:YES];

but this code remove my subview before I push cancelButtonTitle, how can I do?

Yes, implement the UIAlertViewDelegate method alertView:didDismissWithButtonIndex: and dismiss your view there.

Set the delegate to self first:

...
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Done!" 
                                                    message:[@"It's all ok!"]
                                                   delegate:self
                                          cancelButtonTitle:@"OK" 
                                          otherButtonTitles:nil];
...

Could look like this:

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex 
{
    if (buttonIndex == [alertView cancelButtonIndex]) {
        [self dismissModalViewControllerAnimated:YES];
    }
}
