UITableViewCell中的自定义附件视图向表视图控制器发送消息的好方法是什么?

当我不得不这样做的时候,我是这样做的:

//when adding accessoryView to cell in cellForRowAtIndexPath:
UIButton *b = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[b addTarget:self action:@selector(doAction:) forControlEvents:UIControlEventTouchUpInside];
cell.accessoryView = b;

//the handling method
- (void)doAction:(id)sender {
    NSIndexPath *indexPath = [table indexPathForCell:(UITableViewCell *)[sender superview]];
    // code goes here, indexPath tells you what row was touched
}

应使用uibutton以外的控件。
