    copied!<p>I want to pause the screen when an alert is shown on the screen then undo the pause when the alert is dismissed. How would I do that? Here is my view controller:</p> <pre><code>- (void)viewDidLoad {NSLog(@"viewDidLoad"); [super viewDidLoad]; [self generate]; [self.answer becomeFirstResponder]; UIAlertView *alert; {alert = [[UIAlertView alloc] initWithTitle:@"Welcome to iCanMultiply!" message:@"Tap 'Start' to start the game" delegate: self cancelButtonTitle:@"Start" otherButtonTitles: nil]; } [alert show]; [alert release]; alertTimer = [NSTimer scheduledTimerWithTimeInterval:10 target:self selector:@selector(showAlert) userInfo:nil repeats:YES]; } -(void)showAlert { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Game Over" message:@"You ran out of time" delegate:self cancelButtonTitle:@"Try Again" otherButtonTitles: nil]; [alert show]; [alert release]; } - (IBAction)submit:(id)sender { int num = [answer.text intValue]; UIAlertView *alert; if (num == label.tag) { NSUInteger messageCount = [messagesCorrect count]; int randomMessageIndex = arc4random() % messageCount; alert = [[UIAlertView alloc] initWithTitle:@"Correct!" message:[messagesCorrect objectAtIndex:randomMessageIndex] delegate:self cancelButtonTitle:@"Next Question" otherButtonTitles: nil]; alert.tag = 1; } else { NSUInteger messageCount = [messagesIncorrect count]; int randomMessageIndex = arc4random() % messageCount; alert = [[UIAlertView alloc] initWithTitle:@"Wrong!" message:[messagesIncorrect objectAtIndex:randomMessageIndex] delegate:self cancelButtonTitle:@"Try Again" otherButtonTitles: nil]; } [alert show]; [alert release]; } - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if (alertView.tag == 1) { [self generate]; answer.text = @""; } } -(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex { } </code></pre> <p>Please note that my App Delegate is the same as it was when I first started working on the app.</p>
