使用Data.plist时，在表中添加披露按钮

如何解决使用Data.plist时，在表中添加披露按钮

|| 我已经从data.plist创建了一个表，并试图弄清楚如何在第二层到第三层表中添加显示按钮。它将用于向制作图片的学生艺术家添加UIView \“ credits \”。但是，我需要确保名称可以更改，因为表将容纳来自不同学生的不同文件。因此，例如，案例1-3都是Aubrey的作品，案例4-6则是乔什的作品，依此类推。 任何帮助都会很棒。

解决方法

        如果要在单元格中指示公开，则可以使用属性“ 1”。

cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;

哪个可以有这些

typedef enum {
    UITableViewCellAccessoryNone,// don\'t show any accessory view
    UITableViewCellAccessoryDisclosureIndicator,// regular chevron. doesn\'t track
    UITableViewCellAccessoryDetailDisclosureButton,// blue button w/ chevron. tracks
    UITableViewCellAccessoryCheckmark               // checkmark. doesn\'t track
} UITableViewCellAccessoryType;
