我想做这样的事情，我希望我的每个JSON数据（来自PHP）显示在表的每个单元格中。 JSON数据包括文本和图像。现在我只能显示文字，但无法提取图像。例如，我想在Section：New Meter Details中显示图像，而我仍然可以在其他单元格中显示文本。 是否可以为文本和图像重复使用表格视图？请提供建议。这是我的JSON数据，我已将其更改为swift词典：

答案 0 :(得分：0)
如果要与图像分开显示文本，则必须在故事板中为图像设置另一个单元格原型。为其分配不同的单元格标识符，当您需要图像单元格时，使用新的单元格标识符创建它，类似于您在此处执行的操作：
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as UITableViewCell!
如果您希望文本和图像都在一个表格单元格中，那么您只需修改现有原型以适应两者。如果您需要其他信息，请告诉我。
