Ios 是否可在滚动视图或表格视图标题中使用？

我目前正在构建一个应用程序，将一些数据解析到

UITableView

。我正在使用自定义的

UITableViewCell

类

我想在

UITableView

之前和顶部添加一个

UIImage

，就像下面的

UIImage

一样。我的问题是我是否应该去一个head并创建一个包含

UIImage

的自定义

UITableView

标题视图？或者我是否应该将

UITableView

和

UIImageView

放在

UIScrollView

中

我该怎么做

当我在

UITableView

中滚动时，我希望顶部的

UIImage

消失，就像它是表视图中的一行一样

我真的很感激一些解决方案

谢谢
