ZF2 ACL check link in view

I have set up my roles, resources and permissions in my bootstrap, and in my layout have set up a navigation menu based on this, and this works.

What I am attempting to do now is create an admin panel with edit / delete links IF the current logged in user has those permissions. e.g. I may have multiple roles that can view a list of cms pages, but only certain roles can edit a cms page, and only certain roles can delete a cms page.

At the moment I am just checking if the user is logged in:

<?php if($user = $this->identity()): ?>
    <?php if($user['role'] == 'admin'):?>
        <a href="/delete-url">Delete</a>
    <?php endif;?>
<?php endif;?>

How do I check the permissions of the current user role for the specified resource from the view for an arbitrary link (as above)?

The ACL view helper is injected into the layout, so to check if a role has access to a resource, we can call $this->layout()->acl->isAllowed.

In this code snippet, we check if the user is logged in ($this->identity() returns false if not logged in, or an array of details if logged in), then if the user has 'delete' permission to the resource:

<?php if($user = $this->identity()); //is logged in? ?>
    <?php if($this->layout()->acl->isAllowed($user['role'], $resource, 'delete')):?>
        <a href="/delete-url">Delete</a>
    <?php endif;?>
<?php endif;?>

isAllowed signature is isAllowed($role = null, $resource = null, $privilege = null)
