Question

I am trying to make a game on Xcode and I would like an alert message to pop up when the user reaches a certain score, say 100 points. I’ve got the code to make an alert pop up when the view loads up. But what I would like is for the alert message to only show when the player gets to a certain score.

The game’s scoring works like this: every time the player clicks/taps a button, he gets one point, so he gets 100 points after tapping 100 times.

Here’s the code to make the alert message pop up when the view loads up:

- (void)viewDidLoad
{  
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Tile" message:@"This is the message" delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];

    [alert show];
    [alert release];

    [super viewDidLoad];
}

In your button action call method to show alert when point reaches 100.

For example

- (void) buttonAction {
    point++;
    if(point == 100)
      [self showAlert];
}

- (void) showAlert {

        UIAlertView *alert = [[UIAlertView alloc]

                          initWithTitle:@"Tile"
                          message:@"This is the message" 
                          delegate:nil 
                          cancelButtonTitle:@"Dismiss" 
                          otherButtonTitles:nil];

       [alert show];
        [alert release];
}
