How do I dismiss the iOS keyboard?

Question

I have a UITextfield that i\'d like to dismiss the keyboard for. I can\'t seem to make the keyboard go away no matter what code i use.

If you don't know which textField is the first responder you can find it. I use this function:

UIView *resignFirstResponder(UIView *theView)
{
    if([theView isFirstResponder])
    {
        [theView resignFirstResponder];
        return theView;
    }
    for(UIView *subview in theView.subviews)
    {
        UIView *result = resignFirstResponder(subview);
        if(result) return result;
    }
    return nil;
}

Then in your code call:

    UIView *resigned = resignFirstResponder([UIScreen mainScreen]);
