子类按钮来存储所需的值，可能创建一个协议(ControlWithData或其他)。在将按钮添加到表视图单元格时设置该值。在润色事件中，查看发送方是否遵守协议并提取数据。我通常存储对实际对象的引用，该对象呈现在表格视图单元格中。

// 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。

A better way would be to subclass your button and add a indexPath property to it.

//Implement a subclass for UIButton.

@interface NewButton:UIButton
@property(nonatomic, strong) NSIndexPath *indexPath;


Make your button of type NewButton in the XIB or in the code whereever you are initializing them.

Then in the cellForRowAtIndexPath put the following line of code.

button.indexPath = indexPath;

return cell; //As usual



Now in your IBAction

-(IBAction)buttonClicked:(id)sender{
   NewButton *button = (NewButton *)sender;

//Now access the indexPath by buttons property..

   NSIndexPath *indexPath = button.indexPath; //:)
}

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;

你可以使用标签模式:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
     NSString *identifier = @"identifier";
     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
     if (cell == nil) {
         cell = [[UITableView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
         [cell autorelelase];

         UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(10, 5, 40, 20)];
         [button addTarget:self action:@selector(buttonPressedAction:) forControlEvents:UIControlEventTouchUpInside];
         [button setTag:[indexPath row]]; //use the row as the current tag
         [cell.contentView addSubview:button];

         [button release];
     }

     UIButton *button = (UIButton *)[cell viewWithTag:[indexPath row]]; //use [indexPath row]
     [button setTitle:@"Edit" forState:UIControlStateNormal];

     return cell;
}

- (void)buttonPressedAction:(id)sender
{
    UIButton *button = (UIButton *)sender;
    //button.tag has the row number (you can convert it to indexPath)
}

我是这样做的。简洁明了:

- (IBAction)buttonTappedAction:(id)sender
{
    CGPoint buttonPosition = [sender convertPoint:CGPointZero
                                           toView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];
    ...
}
