如何删除UITableViewCell第一行的垂直间距

Question

我有一个ViewController和TableView。

当我尝试配置我的单元格时，我在顶部和原型开始之间获得了这个空间（从最顶层到单词＆＃34;原型单元格＆＃34;）

在跑步模式下，它看起来非常糟糕

当我尝试以任何方式选择PrototypeCellsCount时出现。请帮我把它删除。

它就像一种错误，有时会发生，有时候不会，尝试按照以下方式调整foo中的SELECT categories.category_id, categories.category_name, subcategories.subcategory_name, categories.category_data, categories.category_icon FROM categories INNER JOIN subcategories ON subcategories.category_id=categories.category_id"; ：

public static function getAllCategories()
{
    $database = DatabaseFactory::getFactory()->getConnection();

    $sql = "
    SELECT c.category_id
         , c.category_name
         , s.subcategory_name
         , c.category_data
         , c.category_icon 
      FROM categories c
      JOIN subcategories s 
        ON s.category_id = c.category_id;
     ";

    $query = $database->prepare($sql);
    $query->execute();

    $all_categories = array();

    foreach ($query->fetchAll() as $category) {

        array_walk_recursive($category, 'Filter::XSSFilter');

        $all_categories[$category->category_id] = new stdClass();
        $all_categories[$category->category_id]->category_id = $category->category_id;
        $all_categories[$category->category_id]->category_data = $category->category_data;
        $all_categories[$category->category_id]->category_icon = $category->category_icon;
        $all_categories[$category->category_id]->category_name = $category->category_name;
        $all_categories[$category->category_id]->subcategory_name = $category->subcategory_name;
    }

    return $all_categories;
}

我希望这对你有所帮助。

尝试检查＆＃34;调整滚动视图插图＆＃34;在建设者。这通常可以修复像这样的间距问题。
