Check if a UIAlertView is showing

Question

I have a method that posts HTTP data and displays a UIAlertView if there is an error. If I have multiple HTTP post I will show multiple UIAlertView for every error.

I want to show a UIAlertView only if is not showing other UIAlertView. How can I determine this?

Answer 1

Why not just check the visible property, maintained by the UIAlertView class?

if (_alert) //alert is a retained property {     self.alert = [[[UIAlertView alloc] initWithTitle:@"Your Title"                                              message:@"Your message"                                              delegate:self                                    cancelButtonTitle:@"Cancel"                                    otherButtonTitles:@"OK"] autorelease]; } if (!_alert.visible) {     [_alert show]; }
