与卫生组织纽扣电池的索引UITableCell按钮touchUpInside被点击

Question

我有UITableCells一个UITable其看起来如下：

[myLabel则myButton]

[myLabel则myButton]

[myLabel则myButton]

[myLabel myButton的]

我想我handlerCellButtonClicked也得到的细胞指数的参考。如何在触摸按钮时获得对此索引的引用？

/** called by table to get the cell needed by the index */ 
-(UITableViewCell*)tableView:(UITableView *) tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ 
    ... 
    //init cell 
    ... 
    //configure the cells custom button handlers 
    [cell.myButton addTarget:self action:@selector(handlerCellButtonClicked) forControlEvents:UIControlEventTouchUpInside]; 

    return cell; 
} 

/** handler when the button in the cell is clicked */ 
- (void)handlerCellButtonClicked{ 
    NSLog(@"cell myButton clicked"); 
}

使用UIButton Tag财产。

-(UITableViewCell*)tableView:(UITableView *) tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ 

    //init cell 
    //configure the cells custom button handlers 

    cell.myButton.tag = indexPath.row; 
    [cell.myButton addTarget:self action:@selector(handlerCellButtonClicked:) forControlEvents:UIControlEventTouchUpInside]; 

    return cell; 
} 

/** handler when the button in the cell is clicked */ 
- (void)handlerCellButtonClicked:(UIButton *)sender 
    { 
    NSLog(@"%d cell myButton is clicked", sender.tag); 
    }
