Question

Basically, what I try to do is to add multiple confirmationalerts…but I just cant get it to work. No matter what confirmationalert i press, the “Continue” button leads to the exact same thing (a body without text and a subject with “XXXX”)…
Any idea how to make the confimationalerts to lead to different things?

EDIT 2; No matter what button I press (continue or dismiss), the app sends the user to mail.app…

        -(IBAction)mail {

                    UIAlertView *mail = [[UIAlertView alloc] init];
                        [mail setTag:ALERTVIEW_MAIL_TAG];
                        [mail setTitle:@"Open mail"];
                        [mail setMessage:@"....."];
                        [mail setDelegate:self];
                        [mail addButtonWithTitle:@"Continue"];
                        [mail addButtonWithTitle:@"Dismiss"];
                        [mail show];
                        [mail release];

                    }

                    -(IBAction)feedback {
                        UIAlertView *feedback = [[UIAlertView alloc] init];
                        [feedback setTag:ALERTVIEW_TIPSA_TAG];
                        [feedback setTitle:@"Open mail"];
                        [feedback setMessage:@"....."];
                        [feedback setDelegate:self];
                        [feedback addButtonWithTitle:@"Continue"];
                        [feedback addButtonWithTitle:@"dismiss"];
                        [feedback show];
                        [feedback release];
                    }

- (void)showConfirmAlert
                    {   
                    }   

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
                   if([alertView tag] == ALERTVIEW_FEEDBACK_TAG) {
                        NSURL *url = [[NSURL alloc] initWithString:@"mailto:?subject=XXXX"];
                        [[UIApplication sharedApplication] openURL:url];
                        [url release];
                    }

        else if (buttonIndex == 1) {
        }



           else  if ([alertView tag] == ALERTVIEW_MAIL_TAG) {
                        NSString *subject = @"YYYY";
                        NSString *body = @".....";
                        NSString *path = [NSString stringWithFormat:@"mailto:?subject=%@&body=%@", subject, body];
                        NSURL *url = [NSURL URLWithString:[path stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
                        [[UIApplication sharedApplication] openURL:url];
                    }

            else if (buttonIndex == 1) {
        }

    }

You’ll need to set a tag on your UIAlertView objects and switch on them in your delegate method, this is why the delegate method takes in the UIAlertView, so you can do stuff based on which object the button was pressed.

#define ALERTVIEW_MAIL_TAG     100
#define ALERTVIEW_FEEDBACK_TAG 101


- (IBAction) feedback {
   UIAlertView *feedback = [[UIAlertView alloc] init];
   [feedback setTag:ALERTVIEW_FEEDBACK_TAG];
   //...
}

- (IBAction) mail {
   UIAlertView *mail = [[UIAlertView alloc] init];
   [mail setTag:ALERTVIEW_MAIL_TAG];
}

-(void) alertView:(UIAlertView *) alertView clickedButtonAtIndex:(NSInteger) buttonIndex {
  if([alertView tag] == ALERTVIEW_MAIL_TAG) {
     //do stuff...
  } else {
     //do other stuff...
  }
}
