我在每个单元格中有一个表格视图，两个按钮作为编辑和取消。当我在同一单元格编号中同时单击编辑按钮时，取消按钮图像应该改变。例如。当用户选择第二个单元格编辑按钮时，只有第二个单元格中的取消按钮应更改其图像。

我的问题是当我单击任何单元格编辑按钮时，另一个单元格取消按钮图像会自动更改。

我希望当用户单击第一个单元格时，只有第一个单元格取消按钮应该更改而不是其他单元格？请给我样品我们怎么能做到这一点？据我所知，这种重复使用细胞的原因？

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
     simpleTableIdentifier = @"MenuNameCell";
     MenuNameCell *cell = (MenuNameCell *)[tableView    dequeueReusableCellWithIdentifier:simpleTableIdentifier];

      if (cell== nil) {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MenuNameCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
        NSLog(@"---------new cell agin");   
    }
       else
    {
        NSArray *arrayView = [cell.contentView subviews];
        for (UIView *vTemp in arrayView)
        {
            [vTemp removeFromSuperview];
        }

        NSLog(@"---No New Cell hiiii");

    }
    // Creating Label Menu Name

您正在使用自定义单元格，然后将此代码添加到您的自定义类中并获取特定单元格的特定发件人

-(IBAction)yourButtonMehod:(id)sender
{
    UIView *senderButton = (UIView*) sender;
    NSIndexPath *indexPath = [(UITableView *)self.superView indexPathForCell: (UITableViewCell*)[[senderButton superView]superView]];
}

现在，您可以获取发件人并使用 indexpath.row 您可以做任何事情

在您的按钮操作方法中

-(IBAction)cellButtonPressed:(id)sender withEvent:(UIEvent *)event
{
    UITouch * touch = [[event allTouches] anyObject];
    CGPoint location = [touch locationInView: bulletinTable];
    NSIndexPath * indexPath = [bulletinTable indexPathForRowAtPoint: location];
}

还有你的 cellForRowAtIndexPath 方法

[cell.accessory addTarget:self action:@selector(cellButtonPressed:withEvent:) forControlEvents:UIControlEventTouchUpInside];

这应该有效。
