Question

i need to pop up alert when my application loaded… I called it didfinished launching..
after clicking ok button need to show another alert message i use clickedButtonAtIndex…

Now when I clicked the ok button its calling again and again.. the alertview..

I need to call only once… what to do?

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

    // Override point for customization after application launch.

    // Add the tab bar controller's view to the window and display.
    [window addSubview:tabBarController.view];
    [window makeKeyAndVisible];
    viewControllersList = [[NSMutableArray alloc] init];

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"Alow this app to use your GPS location"
    delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
    [alert show];
    [alert release];

}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{


    if (buttonIndex==0) {
        NSLog(@"NO");
    }
    else    {

        NSLog(@"Yes");
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"Do you want's to receive Push messages."
        delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
        [alert show];
        [alert release];
    }

}

Define each UIAlertView and in the delegate look for which Alert to respond to:

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

    if(alert1) {
        if (buttonIndex==0) { 

            NSLog(@"NO"); 
        } else {

            NSLog(@"Yes");
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"Do you want's to receive Push messages." delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
            [alert show];
            [alert release];
        }
    } else {

        /*  the second alertview  using the same buttonIndex  */
    }

}
