Alert view

How to make a alert view that says. Do you want to make a call : "cancel" "ok"

This is my code

    <p>
- (IBAction)makeCall:(id)sender {

     NSString *phoneNumber = self.phonecall; // dynamically assigned
     NSString *phoneURLString = [NSString stringWithFormat:@"tel:%@", phoneNumber];
     NSURL *phoneURL = [NSURL URLWithString:phoneURLString];
     [[UIApplication sharedApplication] openURL:phoneURL];

    if ([UIApplication instancesRespondToSelector:@selector(canOpenURL:)])  {   NSURL *aURL = [NSURL URLWithString:@"tel:"];   if ([[UIApplication sharedApplication] canOpenURL:aURL])    {     [[UIApplication sharedApplication] openURL:aURL];   } }

 }

</p>
    ```

This is made very clear in making a ribbit app;

        ```UIAlertView *alertView = [[ UIAlertView alloc] initWithTitle:@"<Title>" message:@"Do you want to make a call?" delegate:nil cancelButtonTitle:@"cancel" otherButtonTitles: @"ok"];

    [alertView show]; ```
