为什么UITableViewCellSeparator的位置错误？

Question

节中的行数为1; 索引路径中行的高度为：

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    return  [LZHThreadsNoticeTableViewCell cellHeightForThreadsNotice:_myThreadsDataArray[tag-1][indexPath.row]];
}

高度约为95.0f; 我定制了UITableViewCell

LZHThreadsNoticeTableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:reusableCellWithIdentifier];
    if (cell==nil) {
        cell=[[LZHThreadsNoticeTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reusableCellWithIdentifier];
    }
    [cell configureThreadsNotice:_myThreadsDataArray[tag-1][indexPath.row]];
    return cell;

分离线位于细胞的中心

按下单元格时如下所示：

那么为什么分隔线显示在错误的位置？谢谢。

布局子视图方法如下：

-(void)layoutSubviews{
[_postTimeLabel sizeToFit];
_postTimeLabel.frame=CGRectMake(_viewWidth-_postTimeLabel.frame.size.width-LZHThreadsNoticeDistanceBetweenViews, LZHThreadsNoticeDistanceBetweenViews, _postTimeLabel.frame.size.width, _postTimeLabel.frame.size.height);

CGSize opticalTitleLableSize=[_titleLabel sizeThatFits:CGSizeMake(_viewWidth-3*LZHThreadsNoticeDistanceBetweenViews-_postTimeLabel.frame.size.width, 9999)];
_titleLabel.frame=CGRectMake(LZHThreadsNoticeDistanceBetweenViews, LZHThreadsNoticeDistanceBetweenViews, opticalTitleLableSize.width, opticalTitleLableSize.height);

CGSize opticalMyReplyLableSize=[_myReplyLabel sizeThatFits:CGSizeMake(_viewWidth-2*LZHThreadsNoticeDistanceBetweenViews, 9999)];
_myReplyLabel.frame=CGRectMake(LZHThreadsNoticeDistanceBetweenViews, _titleLabel.frame.origin.y+_titleLabel.frame.size.height+LZHThreadsNoticeDistanceBetweenViews,opticalMyReplyLableSize.width, opticalMyReplyLableSize.height);


CGSize opticalNoticeLabelSize=[_noticeLabel sizeThatFits:CGSizeMake(_viewWidth-2*LZHThreadsNoticeDistanceBetweenViews, 9999)];
_noticeLabel.frame=CGRectMake(LZHThreadsNoticeDistanceBetweenViews, _myReplyLabel.frame.origin.y+_myReplyLabel.frame.size.height+LZHThreadsNoticeDistanceBetweenViews, opticalNoticeLabelSize.width, opticalNoticeLabelSize.height);

_seperatorLabel.backgroundColor=LZHThreadsNoticeSeperatorColor;
_seperatorLabel.frame=CGRectMake(LZHThreadsNoticeDistanceBetweenViews, _noticeLabel.frame.origin.y+_noticeLabel.frame.size.height+LZHThreadsNoticeDistanceBetweenViews, _viewWidth-LZHThreadsNoticeDistanceBetweenViews, 1.0f);
}

我有五个标签，从上到下。 细胞高度方法是：

+(CGFloat)cellHeightForThreadsNotice:(LZHThreadsNotice *)threadsNotice{
CGFloat viewWidth=[[UIScreen mainScreen]bounds].size.width;

UILabel *noticeLabel=[[UILabel alloc]init];
noticeLabel.font=[UIFont systemFontOfSize:LZHThreadsNoticeSmallFontSize];
if (threadsNotice.noticeType==LZHTHreadsNoticeTypeReply) {
    noticeLabel.text=[NSString stringWithFormat:@"%@答复您说：%@",threadsNotice.user.userName,threadsNotice.noticeContext];
}else{
    noticeLabel.text=[NSString stringWithFormat:@"%@引用您说：%@",threadsNotice.user.userName,threadsNotice.noticeContext];
}
noticeLabel.numberOfLines=0;
noticeLabel.lineBreakMode=NSLineBreakByCharWrapping;
noticeLabel.font=[UIFont systemFontOfSize:LZHThreadsNoticeSmallFontSize];
CGSize opticalNoticContextLableSize=[noticeLabel sizeThatFits:CGSizeMake(viewWidth-2*LZHThreadsNoticeDistanceBetweenViews, 9999)];


UILabel *titleLabel=[[UILabel alloc]init];
titleLabel.text=threadsNotice.title;
titleLabel.numberOfLines=0;
titleLabel.lineBreakMode=NSLineBreakByCharWrapping;
titleLabel.font=[UIFont boldSystemFontOfSize:LZHThreadsNoticeBigFontSize];
UILabel *postTimeLabel=[[UILabel alloc]init];
postTimeLabel.font=[UIFont systemFontOfSize:LZHThreadsNoticeSmallFontSize];
postTimeLabel.text=threadsNotice.postTime;
[postTimeLabel sizeToFit];

CGSize opticalTitleLableSize=[titleLabel sizeThatFits:CGSizeMake(viewWidth-postTimeLabel.frame.size.width-3*LZHThreadsNoticeDistanceBetweenViews, 9999)];

UILabel *myReplyContextLabel=[[UILabel alloc]init];
myReplyContextLabel.text=[NSString stringWithFormat:@"您的帖子：%@",threadsNotice.myReplyContext];
myReplyContextLabel.numberOfLines=0;
myReplyContextLabel.lineBreakMode=NSLineBreakByCharWrapping;
myReplyContextLabel.font=[UIFont systemFontOfSize:LZHThreadsNoticeSmallFontSize];

CGSize opticalMyReplyContextLabelSize=[myReplyContextLabel sizeThatFits:CGSizeMake(viewWidth-2*LZHThreadsNoticeDistanceBetweenViews, 9999)];

return 4*LZHThreadsNoticeDistanceBetweenViews+opticalTitleLableSize.height+opticalNoticContextLableSize.height+opticalMyReplyContextLabelSize.height+1.0f;
}
