Is there a difference between using a custom UITableViewCell vs UITableViewHeaderFooterView?

Question

I'm relatively new to iOS swift, but is there a difference between doing this

class MyCustomHeaderSection: UITableViewHeaderFooterView
{
    ...
}

myTableView.register(MyCustomHeaderSection.self, forHeaderFooterViewReuseIdentifier: "section_header")

And the following approach

class MyCustomHeaderSection: UITableViewCell
{
    ...
}

myTableView.register(MyCustomHeaderSection.self, forCellReuseIdentifier: "section_header")

Answer 1

UI 方面没有区别，两者都可以作为页眉/页脚使用，但MyCustomHeaderSection: UITableViewHeaderFooterView真正用于页眉/页脚，而class MyCustomHeaderSection: UITableViewCell用于表的实际内容单元格
