我有一个自定义的帖子类型，叫做预测。代码如下：

<?php
// Register forecasts cpt
function forecasts() {
    $labels = array(
        \'name\'                  => _x( \'Forecasts\', \'Post Type General Name\', \'reedbc\' ),
        \'singular_name\'         => _x( \'Forecast\', \'Post Type Singular Name\', \'reedbc\' ),

        \'filter_items_list\'     => __( \'Filter items list\', \'reedbc\' ),

    $args = array(

    );
    register_post_type( \'forecasts\', $args );
}
add_action( \'init\', \'forecasts\', 0 );

WP Admin仍显示默认pin图标。我试着清理我的永久链接，但这不起作用。

有什么想法吗？
