iPhone:UITableView手机上的按钮报告错误标签

我有一个包含图像和按钮的表。每个按钮都有一个不同编号的标签。单击时,所有按钮执行相同的方法。我将在它们运行的方法上使用按钮的标记,以了解单击了哪个按钮。

问题是正在报告的按钮标签错误。我想象当这些单元被重用时,有什么东西干扰了标签。

这是我用来动态填充表的代码:

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

if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
                                   reuseIdentifier:MyIdentifier] autorelease];

    UIButton *buyButton = [[UIButton alloc] initWithFrame:CGRectMake( 220, 4, 100, 35)];

    buyButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    buyButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
    [buyButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    buyButton.titleLabel.font = [UIFont boldSystemFontOfSize:14];
    [buyButton setBackgroundImage:newImage forState:UIControlStateNormal];
    [buyButton addTarget:self action:@selector(buyNow:) forControlEvents:UIControlEventTouchDown];
    [buyButton setTag: 1]; // I have to do this, to locate the button a few lines below
    [cell addSubview:buyButton];
    [buyButton release];
}


 imageU = [[[UIImage alloc]initWithContentsOfFile:[[NSBundle mainBundle] 
                              pathForResource:[NSString stringWithFormat: @"table-pg%d",numberX] 
                                                    ofType:@"jpg"]] autorelease];
    cell.imageView.image = imageU;

    UIButton * myButton = (UIButton *) [cell viewWithTag:1];        
    [myButton setTitle:NSLocalizedString(@"buyKey", @"") forState:UIControlStateNormal]; 

    UIImage *newImage = [[[[UIImage alloc]initWithContentsOfFile:[[NSBundle mainBundle] 
                                             pathForResource: @"whiteButton" ofType:@"png"]] autorelease]
                                                     stretchableImageWithLeftCapWidth:12.0f topCapHeight:0.0f];

    [buyButton setTag:indexPath.row]; // the button's tag is set here

return cell;

}

这就是BuyNow方法…

- (void) buyNow:(id)sender {

    int index = [sender tag];

    NSLog(@"button clicked = %d", index);
}

按钮被报告为单击的一个周期,从0到6,没有超过6的数字被报告。我认为这与被重用的细胞相对应,为什么数字不变,是个谜。

如何解决这个问题?

谢谢你的帮助。
