我在将 UIImageView 添加到单个 UITableView 单元格时遇到了真正的麻烦。在我的故事板中，我有一个 UITableViewController 和四个原型动态单元格。其中三个与正常的左侧细节单元格一样好，并且工作正常。但是其中一个我需要有一个 UIImageView 。
所以我在单元格中添加了所说的视图，给单元格一个带有属性的自定义类，这样我就可以访问图像视图。
我有以下单元格：
标题单元格。
图像单元。
网址单元格。
笔记单元格。
表格视图的内容会根据用户是否要添加 URL、注释或图像而改变。所以用户总是看到标题单元格和其他单元格之一。
这是我的代码，无论出于何种原因，我都无法让 UIImageView 显示在该图像单元格上。
