Hi,

Following code can be used to validate the user input in iPhone and iPad applications.

if([loginID.text isEqualToString:@""]) {
    UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:@"Field Error"
                message:@"Please enter Login ID!" delegate:self 
                cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alertView show];
    [alertView release];
}

Thanks
