- (IBAction)buttonPressed{
    UIActionSheet *actionSheet = [[UIActionSheet alloc]initWithTitle:@"Are you sure?" delegate:self cancelButtonTitle:@"No way" destructiveButtonTitle:@"Yes,I'm sure!" otherButtonTitles: nil];
    [actionSheet showInView:self.view];
}
- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{
    if (buttonIndex != [actionSheet cancelButtonIndex]) {
        NSString *msg = nil;
        if (nameField.text.length > 0) 
            msg = [[NSString alloc] initWithFormat:@"you can breathe easy, %@, everything want OK.", nameField.text];
         else 
            msg = @"you can breathe easy, everything want OK.";
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"something wan done" message:msg delegate:self cancelButtonTitle:@"Phew!" otherButtonTitles: nil];
            [alert show];
