UIS图像对象。在profileviewcontroller的viewdidLoad（）中添加断点，并检查self.profileImage和self.name是否包含我们从tableviewcell传递的值。让我知道它是否有效。感谢这意味着问题在于填写UIImageView和UILabel时。在这些区域上添加断点。检查结果是否相同。然后确保正确填写uiimageview和uilabel。另外，单击仅适用于第一行我希望它适用于所有单元格如果在不同单元格上选择时调用了didselect。还要检查profilepicarray和friendsnamearray是否在indexPath.row处包含值
