IMPORTANT NOTICE

There are a lot requests and issus regarding the (pre-)selection of post types and/or taxonomies. But there's one main problem within WordPress: Post Types, especially CPTs, are registered for each individual site at run time. So there's no easy possibilty to grab post types and taxonomies from other sites.

This plugin is no longer being developed! If anyone has the knowledge and time further developing the plugin, feel free to use the existing code.

Array
(
    [selected_posts] => Array
        (
            [0] => WP_Post Object
                (
                    [ID] => 3
                    [post_author] => 1
                    [post_date] => 2014-09-18 19:56:07
                    [post_date_gmt] => 2014-09-18 19:56:07
                    [post_content] => 
                    [post_title] => My Sample Post
                    [post_excerpt] => 
                    [post_status] => publish
                    [comment_status] => open
                    [ping_status] => open
                    [post_password] => 
                    [post_name] => sample-post
                    [to_ping] => 
                    [pinged] => 
                    [post_modified] => 2014-09-18 19:56:07
                    [post_modified_gmt] => 2014-09-18 19:56:07
                    [post_content_filtered] => 
                    [post_parent] => 0
                    [guid] => http://yourdomain.com/multisite/?p=3
                    [menu_order] => 0
                    [post_type] => post
                    [post_mime_type] => 
                    [comment_count] => 0
                    [filter] => raw
                )

        )

    [site_id] => 5
)

or with all post ids (if you choose 'Post ID'). The second array [site_id] holds the site id of your selected multisite.

Array
(
    [selected_posts] => Array
        (
            [0] => 3
        )

    [site_id] => 5
)

To get the post on the frontend you need to do a foreach loop.

With Post ID

	    // get field value
	    $posts = get_field('field_name');

	    if( $posts ):
	        // switch to multisite
	        switch_to_blog( $posts['site_id'] ); ?>
	        <ul>        
	            <?php foreach ($posts['selected_posts'] as $post): // variable must be called $post (IMPORTANT) ?>
	                <?php setup_postdata($post); ?>
	                <li>
	                    <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
	                    <span>Custom field from $post: <?php the_field('author'); ?></span>
	                </li>
	            <?php endforeach; ?>
	        </ul>
	        <?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
	        <?php restore_current_blog(); // IMPORTANT switch back to current site?>
	    <?php endif; ?>

With Post Object

        // get field value
        $posts = get_field('field_name');

        if( $posts ):
            // switch to multisite
            switch_to_blog( $posts['site_id'] ); ?>
            <ul>        
                <?php foreach ($posts['selected_posts'] as $acf_post): ?>
                    <li>
                        <a href="<?php echo $acf_post->guid; ?>"><?php echo $acf_post->post_title; ?></a>
                        <span>Custom field from $post: <?php the_field('author', $acf_post->ID); ?></span>
                    </li>
                <?php endforeach; ?>
            </ul>
            <?php restore_current_blog(); // IMPORTANT switch back to current site?>
        <?php endif; ?>
