给 button 连线成方法 在方法中获取 在storyBoard仔细观察你的button上面一共有几层才能到你的cell， 也就是属一下上面有几个父类才到cell 上面到cell一共有三层 - (IBAction)enterShopButton:(UIButton *)sender  {     UIView *v = [sender superview];//获取父类view     UIView *v1 = [v superview];     UITableViewCell *cell = (UITableViewCell *)[v1 superview];//获取cell     NSIndexPath *indexPathAll = [self.tableView indexPathForCell:cell];//获取cell对应的section     NSLog(@"indexPath:--------%@",indexPathAll); }
