After a calculation, I want to display a pop up or alert box conveying a message to the user. Does anyone know where I can find more information about this?
UIAlertView is probably what you're looking for. Here's an example:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"No network connection" message:@"You must be connected to the internet to use this app." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release];
If you want to do something more fancy, say display a custom UI in your
UIAlertView, you can subclass
UIAlertView and put in custom UI components in the
init method. If you want to respond to a button press after a
UIAlertView appears, you can set the
delegate above and implement the
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex method.
