Magento - Accessing a customer's wishlist

Question

I would like to be able to load a customer's wishlist and return the product id's of the products within the list

I am using:

$wishList = Mage::getSingleton('wishlist/wishlist')->loadByCustomer($customer);
$wishListItemCollection = $wishList->getItemCollection();

The problem is that the arrays in the Item Collection are protected and I can't find any methods to extract the data.

Is there another way to do this?

You're very close to your target.

$wishList = Mage::getSingleton('wishlist/wishlist')->loadByCustomer($customer);
$wishListItemCollection = $wishList->getItemCollection();

if (count($wishListItemCollection)) {
    $arrProductIds = array();

    foreach ($wishListItemCollection as $item) {
        /* @var $product Mage_Catalog_Model_Product */
        $product = $item->getProduct();
        $arrProductIds[] = $product->getId();
    }
}

The array variable $arrProductIds will now contain the list of all Product IDs that have been wishlisted by that specific Customer.
