Objective c 单元格中的文本复制，直到我滚动[图像]才显示

因此，我在tableView中加载了一个YouTube频道，并试图添加正确的持续时间，但有时它根本不显示，当它显示时，如果你仔细看，它后面会有另一个文本

当你看图像1时，你可以看到，在我滚动到一个视频上之前，它没有时间

当您查看图2时，可以看到文本标签在某些位置重复

代码

-（UITableViewCell*）tableView:（UITableView*）tableView cellForRowAtIndexPath:（NSIndexPath*）indexPath
{
静态NSString*CellIdentifier=@“Cell”；
ChanelFeeds*currentFeed=[[xmlParser feeds]objectAtIndex:indexPath.row]；
UITableViewCell*单元格=[tableView dequeueReusableCellWithIdentifier:CellIdentifier]；
如果（单元格==nil）
{
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle重用标识符：CellIdentifier]自动释放]；
totalTime=[self timeFormatted:（[currentFeed duration].intValue）-1]；
如果（[totalTime length]可能会更改为-

if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}

然后，区块-

totalTime = [self timeFormatted:([currentFeed duration].intValue)-1];
    if([totalTime length] <= 4) {

        CGRect contentFrame6 = CGRectMake(0, 66, 30, 13);
        CGRect contentFrame7 = CGRectMake(6, 65, 60, 15);
        UILabel *title3 = [[UILabel alloc] initWithFrame:contentFrame7];
        UIImageView *imv5 = [[UIImageView alloc]initWithFrame:contentFrame6];

        imv5.image=[UIImage imageNamed:@"blackBorder.png"];
        imv5.alpha = 0.8;
        [cell.contentView addSubview:imv5];

        title3.tag = 0013;
        title3.numberOfLines = 1;
        title3.font = [UIFont boldSystemFontOfSize:10];
        [cell.contentView addSubview:title3];
        title3.text = totalTime;
        title3.textColor = [UIColor whiteColor];
        title3.backgroundColor = [UIColor clearColor];
        imv5.backgroundColor = [UIColor clearColor];
        [imv5 release];
        [title3 release];
    } else if([totalTime length] == 5) {
        CGRect contentFrame6 = CGRectMake(87, 64, 30, 13);
        CGRect contentFrame7 = CGRectMake(90, 63, 60, 15);
        UILabel *title3 = [[UILabel alloc] initWithFrame:contentFrame7];
        UIImageView *imv5 = [[UIImageView alloc]initWithFrame:contentFrame6];

        imv5.image=[UIImage imageNamed:@"blackBorder.png"];
        imv5.alpha = 0.8;
        [cell.contentView addSubview:imv5];

        title3.tag = 0013;
        title3.numberOfLines = 1;
        title3.font = [UIFont systemFontOfSize:10];
        [cell.contentView addSubview:title3];
        title3.text = totalTime;
        title3.textColor = [UIColor whiteColor];
        title3.backgroundColor = [UIColor clearColor];
        imv5.backgroundColor = [UIColor clearColor];
        [imv5 release];
        [title3 release];
    }

}else{
    NSData* imageDataTemp = [[NSData alloc] initWithContentsOfURL:[currentFeed thumbnailURL]];
    if(imageDataTemp){
        cell.imageView.image = [UIImage imageWithData:imageDataTemp];
    }else{
        cell.imageView.image = [UIImage imageNamed:@"youtubeLogo.png"];
    }


}

totalTime=[self timeFormatted:（[currentFeed duration].intValue）-1]；
如果（[totalTime length]是的，但是你把图像放在计时器的顶部。你会更清楚：），我的观点是代码应该在
如果（cell==nil）{}
totalTime = [self timeFormatted:([currentFeed duration].intValue)-1];
    if([totalTime length] <= 4) {

        CGRect contentFrame6 = CGRectMake(0, 66, 30, 13);
        CGRect contentFrame7 = CGRectMake(6, 65, 60, 15);
        UILabel *title3 = [[UILabel alloc] initWithFrame:contentFrame7];
        UIImageView *imv5 = [[UIImageView alloc]initWithFrame:contentFrame6];

        imv5.image=[UIImage imageNamed:@"blackBorder.png"];
        imv5.alpha = 0.8;
        [cell.contentView addSubview:imv5];

        title3.tag = 0013;
        title3.numberOfLines = 1;
        title3.font = [UIFont boldSystemFontOfSize:10];
        [cell.contentView addSubview:title3];
        title3.text = totalTime;
        title3.textColor = [UIColor whiteColor];
        title3.backgroundColor = [UIColor clearColor];
        imv5.backgroundColor = [UIColor clearColor];
        [imv5 release];
        [title3 release];
    } else if([totalTime length] == 5) {
        CGRect contentFrame6 = CGRectMake(87, 64, 30, 13);
