我会像你说的那样使用tag属性，像这样设置标签:

[button setTag:indexPath.row];

然后将标签放入buttonPressedAction中，如下所示:

((UIButton *)sender).tag

Or

UIButton *button = (UIButton *)sender; 
button.tag;

// how do I know which button sent this message?
// processing button press for this row requires an indexPath.

其实很简单:

- (void)buttonPressedAction:(id)sender
{
    UIButton *button = (UIButton *)sender;
    CGPoint rowButtonCenterInTableView = [[rowButton superview] convertPoint:rowButton.center toView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:rowButtonCenterInTableView];
    MyTableViewItem *rowItem = [self.itemsArray objectAtIndex:indexPath.row];
    // Now you're good to go.. do what the intention of the button is, but with
    // the context of the "row item" that the button belongs to
    [self performFooWithItem:rowItem];
}

对我来说很好:P

如果你想调整你的目标-操作设置，你可以在方法中包含事件参数，然后使用该事件的触摸来解析触摸的坐标。坐标仍然需要在触摸视图边界内进行解析，但这对某些人来说似乎更容易。

我发现使用父视图的父视图获取单元的indexPath引用的方法非常有效。感谢iphonedevbook.com (macnsmith)的提示链接文本

-(void)buttonPressed:(id)sender {
 UITableViewCell *clickedCell = (UITableViewCell *)[[sender superview] superview];
 NSIndexPath *clickedButtonPath = [self.tableView indexPathForCell:clickedCell];
...

}

虽然我喜欢标签的方式…如果你出于某种原因不想使用标签， 你可以创建一个预制按钮的成员NSArray:

NSArray* buttons ;

然后在渲染tableView之前创建这些按钮，并将它们推入数组。

然后在tableView:cellForRowAtIndexPath:函数中，你可以这样做:

UIButton* button = [buttons objectAtIndex:[indexPath row] ] ;
[cell.contentView addSubview:button];

然后在buttonPressedAction:函数中，就可以做了

- (void)buttonPressedAction:(id)sender {
   UIButton* button = (UIButton*)sender ;
   int row = [buttons indexOfObject:button] ;
   // Do magic
}

在Apple的配件示例中，使用了以下方法:

[button addTarget:self action:@selector(checkButtonTapped:) forControlEvents:UIControlEventTouchUpInside];

然后在触摸处理程序中检索触摸坐标，并从该坐标计算索引路径:

- (void)checkButtonTapped:(id)sender
{
    CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];
    if (indexPath != nil)
    {
     ...
    }
}

使用运行时注入在UIButton中发送NSIndexPath之类的信息怎么样?

1)导入时需要运行时

2)添加静态常数

3)添加NSIndexPath到你的按钮运行时使用:

(虚空)setMetaData:()目标withObject id: (id) newObj

4)按下按钮获取元数据使用:

()元数据:(id)目标

享受

    #import <objc/runtime.h>
    static char const * const kMetaDic = "kMetaDic";


    #pragma mark - Getters / Setters

- (id)metaData:(id)target {
    return objc_getAssociatedObject(target, kMetaDic);
}

- (void)setMetaData:(id)target withObject:(id)newObj {
    objc_setAssociatedObject(target, kMetaDic, newObj, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}



    #On the cell constructor
    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
    ....
    cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    ....
    [btnSocial addTarget:self
                                   action:@selector(openComments:)
                         forControlEvents:UIControlEventTouchUpInside];

    #add the indexpath here or another object
    [self setMetaData:btnSocial withObject:indexPath];

    ....
    }



    #The action after button been press:

    - (IBAction)openComments:(UIButton*)sender{

        NSIndexPath *indexPath = [self metaData:sender];
        NSLog(@"indexPath: %d", indexPath.row);

        //Reuse your indexpath Now
    }
