Question

After a UIAlertView is closed, I would like to reload a view (run viewWillDisappear for the view and viewWillAppear for the view).

How do I do that? I have tried delegating to both nil and self. Here is my code.

- (IBAction)doStuffWhenUIButtonIsClicked:(id)sender
{
    int intSelection = [sender tag];
    NSString* strAlertTitle;
    NSString* strAlertMessage;
    if (intSelection == self.intCorrectChoice) {
        strAlertTitle = @"Correct tag!";
    }
    else {
        strAlertTitle = @"Sorry, incorrect tag!";
    }
strAlertMessage = @"The correct answer was 8.";

    self.answerReaction = [[UIAlertView alloc]
                           initWithTitle: strAlertTitle
                                 message: strAlertMessage
                                delegate: nil
                       cancelButtonTitle:@"Next Question"
                       otherButtonTitles:nil];
    [self.answerReaction show];
}

As you see, I want to load a new question after the user answers one of them.

Answer 1

First, you need to make the view controller that you are in conform to the UIAlertViewDelegate protocol.

Then, before you show the alert, you need to add this line:

self.answerReaction.delegate = self;

Then, implement the didDismissWithButtonIndex delegate method:

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
    [self viewWillDisappear:YES];
    // load your new question
    [self viewWillAppear:YES];
}

That should take care of it!
