将每个单元格设置在自己的组中

My UITableViewCells take up the full viewing area. I'd like to use a grouped table so the cells appear to have rounded corners. Right now, if I set the number of sections to something greater than one, I get the number of sections in grouped style but all the cells repeat in each section. How do I setup the table so each cell is in a section?My UITableViewCells take up the full viewing ar
