  这个怎么样...

  - (UITableViewCell *)cellWithSubview:(UIView *)subview {
      while (subview && ![subview isKindOfClass:[UITableViewCell self]]) subview = subview.superview;
      return (UITableViewCell *)subview;
  }
  
  - (IBAction)buttonClicked:(id)sender {
      UITableViewCell *theCell = [self cellWithSubview:sender];
  }

  实现此目的的一种策略是将带有行号的标记分配给按下的按钮：

  - (UITableViewCell *)tableView:(UITableView *)tableView 
           cellForRowAtIndexPath:(NSIndexPath *)indexpath {
      YourCustomCell *cell = // Code
      cell.button.tag = indexPath.row;
  
      // Other cell preparation code
  
      return cell;
  }
  

  然后，在按钮的操作中，您可以看到其标记是什么来确定对应于以下内容的模型对象：

  - (void)didSelectButton:(id)sender {
      UIButton *button = sender;
      NSInteger tag = button.tag;
  
      YourModelObject *item = self.items[tag];
  
      //    Continue with the business logic for what should
      //    happen when that button is pressed.
  }

  如果使用自定义按钮替换附件详细信息按钮，则可以调用accessoryButtonTappedForRowWithIndexPath：方法 .

  示例 - 将其放在cellForRowAtIndexPath中（设置单元格时）：

  UIButton *myAccessoryButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 125, 24)];
  [myAccessoryButton setImage:[UIImage imageNamed:@"yourImage.png"] forState:UIControlStateNormal];
  [cell setAccessoryView:myAccessoryButton];
  [myAccessoryButton release];
  cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
  

  然后作为一个单独的方法：

  - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:    (NSIndexPath *)indexPath
  {
      //do something
  }

  您需要以这种方式调用此 cellForRowAtIndexPath 方法 .

  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      static NSString *CellIdentifier = @"Cell";
  
      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
      if (cell == nil) {
          cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
          cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
      }
  
  
      button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
      button.frame = CGRectMake(10 , 10, 200, 20);
      [button addTarget:self action:@selector(passRowValueMethod:) forControlEvents:UIControlEventTouchUpInside];
      [button setTag:indexPath.row];
      [button setTitle:[NSString stringWithFormat:@"%d", indexPath.row] forState:UIControlStateNormal];
      [cell addSubview:button];
  
  
      return cell;
  }
  

  然后定义按钮目标方法并在此方法中获取标记值 .

  -(void)passRowValueMethod:(UIButton*)sender
  {
      UIButton *buttonGet = sender;
      NSLog(@"%d", buttonGet.tag);
  }
  

  希望这会帮助你 .

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

  UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
  
  CGRect frame = CGRectMake(0.0, 10.0, 24, 24);
  button.frame = frame;
  [button setTag:((indexPath.section & 0xFFFF) << 16) |
   (indexPath.row & 0xFFFF)];
  [button setImage:[UIImage imageNamed:@"link-buttoni4.png"] forState:UIControlStateNormal];
  [button setImage:[UIImage imageNamed:@"link-button-onclicki4.png"] forState:UIControlStateHighlighted];
  [button setSelected:NO];
  
  // set the button's target to this table view controller so we can interpret touch events and map that to a NSIndexSet
  
  [button addTarget:self action:@selector(checkButtonTapped:) forControlEvents:UIControlEventTouchUpInside];
  button.backgroundColor = [UIColor clearColor];
  cell.accessoryView = button;
  

  }

  • （void）checkButtonTapped：（UIButton *）sender {

  NSUInteger section = ((sender.tag >> 16) & 0xFFFF);
  NSUInteger row     = (sender.tag & 0xFFFF);
  NSLog(@"Button in section %i on row %i was pressed.", section, row);
  

  }

  试试这个，
  你可以知道在这个方法中单击一个单元格的section和row no：

  • （UITableViewCell *）tableView：（UITableView *）tableView cellForRowAtIndexPath：（NSIndexPath *）indexPath {
    }

  1>部分可以得到
  int sectionno = indexPath.section
  2>细胞指数可以得到
  int rowno = indexPath.row
  然后使用你可以得到像这样的表格单元格，

  UITableViewCell *cell=[product_table cellForRowAtIndexPath:[NSIndexPath indexPathForRow:rowno inSection:sectionno]];
