【问题描述】：

我正在使用自定义表格视图单元格显示到表格视图

- (id)initWithFrame:(CGRect)frame reuseIdentifier:(NSString *)reuseIdentifier 
{
if (self = [super initWithFrame:frame reuseIdentifier:reuseIdentifier]) 
{
     m_mail_status = [[UIImageView alloc] initWithFrame:CGRectMake(295, 10, 18, 18)];
    [self addSubview:m_mail_status];

    m_subject = [[UILabel alloc] initWithFrame:CGRectMake(10, 0, 270, 37)];
    UIFont* font = m_subject.font;

    m_subject.font = [UIFont boldSystemFontOfSize:font.pointSize];

    //m_subject.font = [UIFont systemFontOfSize:17];
    [self addSubview:m_subject];

    m_from = [[UILabel alloc] initWithFrame:CGRectMake(10, 37, 200, 15)];
    m_from.font = [UIFont systemFontOfSize:12];
    [self addSubview:m_from];

    m_date = [[UILabel alloc] initWithFrame:CGRectMake(180, 37, 140, 15)];
    m_date.textAlignment= UITextAlignmentRight;
    m_date.font = [UIFont systemFontOfSize:12];
    [self addSubview:m_date];




}
return self;
}

还有我在视图控制器中的代码，

static NSString *MyIdentifier = @"ProductsCell";
InboxViewCell *cell = (InboxViewCell*)[tableView dequeueReusableCellWithIdentifier:MyIdentifier];

//static NSString *CellIdentifier = @"Cell";

// UITableViewCell *cell = nil;// [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
//cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"xx"] autorelease];


if(cell == nil) 
    cell = [[[InboxViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];


    cell.m_subject.text = [[inbox objectAtIndex:indexPath.row] objectForKey:@"subject"];
    cell.m_from.text = [[inbox objectAtIndex:indexPath.row] objectForKey:@"from"];
    cell.m_date.text = [[inbox objectAtIndex:indexPath.row] objectForKey:@"date"];

    if([[[inbox objectAtIndex:indexPath.row] objectForKey:@"**reservation_status**"] isEqualToString:@"1"])     
    {
    cell.m_mail_status.image =  [UIImage imageNamed:@"reservation_symbol.png"];
    }

它在第一次加载时以正确的方式加载当我向下滚动并向上移动时的问题显示所有图像它忽略 if 语句结果

提前致谢

问候，萨蒂什

【解决方案1】：

这样做的原因是单元格被重复使用，您需要在 if 的 else 中重置该图像。
