UITextField help in iPhone (HTTP and HTTPS validation)

Question

Hey All,

I am developing an app and the user has to enter the URL to access the information in the app. If the user forgets to enter the URL in a proper way, I want to prepend http:// and append soap.php to the URL text field. Is there any validation to be done for this or can I append using string methods? Also is there a way to allow HTTPS URL's..does it support or should I perform any validation for this too..please help me..

EDIT:

if ([[serverurlField.text substringToIndex:0]isEqualToString:@"http://"]) {
            syncDelegateImpl.serverURL = serverurlField.text;
        }
        else {
            syncDelegateImpl.serverURL = [NSString stringWithFormat:@"http:// %@",serverurlField.text,@"soap.php"];
        }

[NSString rangeOfString:], [NSMutableString appendString:]and [NSString stringWithFormat:] are your friends.
