How to open the dialog box dynamically in iOS?

how to implement a pop up dialog box in iOS

• 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? Thanks

• Answer:

  Yup, a 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. You might also want to look at the UIActionSheet. Hope this helps!
