重新加载后UICollectionViewCell无法正常显示

Question

我对UICollectionViewCells有一个令人沮丧的问题。我在这个应用程序中使用默认流程。这是问题所在：

初次加载时，“已关闭”标签会在单元格中正确显示。我们通过下拉或转到另一个页面并返回来重新加载CollectionView，“Closed”标签仅显示在第一个单元格上。

“封闭”标签已在IB中添加并命名。我尝试使用标签名称以及标记标签并使用标签参考。

当我调试代码时，它会通过正确的“封闭”标签流程。 “已关闭”标签是实例，不是零。在代码中看来，一切都应该是快乐和好的，但显示它不是。

以下是数据初始加载的屏幕截图：

以下是重新加载的屏幕截图：

现在代码 - 这里是cellForItemAtIndexPath函数：

    - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {

    NSMutableString *topMiddle = [NSMutableString new];
    NSMutableString *bottomMiddle = [NSMutableString new];
    NSMutableString *bottom = [NSMutableString new];

    Tab *theTab = [self.fetchedResultsController objectAtIndexPath:indexPath];

    // figure out the date this started
    [bottomMiddle appendString:@"Start: "];
    [bottomMiddle appendString:[_dateFormatted stringFromDate:[theTab startdate]]];

    // figure out the due date/closed date stuff
    if ([theTab closeddate] != nil) {
        [bottom appendString:@"Closed: "];
        [bottom appendString:[_dateFormatted stringFromDate:[theTab closeddate]]];
    } else if ([theTab duedate] == nil) {
        [bottom appendString:@"No Due Date"];

    } else if ([theTab duedate] != nil){
        [bottom appendString:@"Due: "];
        [bottom appendString:[_dateFormatted stringFromDate:[theTab duedate]]];
    }

    long duedaterange = [self numberOfDaysTillDueDate:[theTab duedate]];

    CreditorCollectionViewCell *cellC;
    if ([[theTab debitor] intValue] == 0) {
        cellC = [collectionView dequeueReusableCellWithReuseIdentifier:reuseCreditorIdentifier forIndexPath:indexPath];
        [cellC.topLabel setText:[theTab name]];

        [topMiddle appendString:@"They Owe: "];
        [topMiddle appendString:@"\n"];
        [topMiddle appendString:[_currencyFormatted stringFromNumber:[theTab amountcurrent]]];
        [cellC.topMiddleLabel setText:topMiddle];

        [cellC.bottomMiddleLabel setText:bottomMiddle];

        [cellC.bottomLabel setText:bottom];

        [cellC setTheTab:theTab];

        // set this as hidden unless it is closed
        if ([theTab closeddate] == nil) {
            [[cellC viewWithTag:102] setHidden:YES];
        } else {
            [[cellC viewWithTag:102] setHidden:NO];
        }

        if ([theTab closeddate] != nil) {
            // the tab is CLOSED
            [cellC setBackgroundColor:[UIColor lightGrayColor]];

            [[cellC viewWithTag:102] setCenter:cellC.center];
            [[cellC viewWithTag:102] setBackgroundColor:[UIColor clearColor]];
            [(UILabel *)[cellC viewWithTag:102] setTextColor:[UIColor darkGrayColor]];

            CGAffineTransform tcheck = [cellC viewWithTag:102].transform;

            // make sure the transform has not been applied already
            if ((tcheck.a == 0 || tcheck.a == 1) && (tcheck.b == 0 || tcheck.b == 1) &&
                (tcheck.c == 0 || tcheck.c == 1) && (tcheck.d == 0 || tcheck.d == 1)) {

                // turn the closed sign
                float angleDim = (cellC.bounds.size.height/cellC.bounds.size.width);
                float angle = atanf(angleDim);

                // apply the trnasformation to angle the closed label
                CGAffineTransform transform = CGAffineTransformRotate([cellC viewWithTag:102].transform, -angle);
                [cellC viewWithTag:102].transform = transform;
            }

        } else if ((duedaterange == 0) && ([bottom containsString:@"No Due Date"])) {
            // either day of or none set
            [cellC setBackgroundColor:[UIColor greenColor]];
        } else if (duedaterange >= 10) {
            // more than 10 days out (green)
            [cellC setBackgroundColor:[UIColor greenColor]];
        } else if (duedaterange < 0) {
            // PAST DUE (red)
            [cellC setBackgroundColor:[UIColor redColor]];
        } else {
            // coming close (yellow)
            [cellC setBackgroundColor:[UIColor yellowColor]];
        }

        return cellC;

    }

    return nil;

}

有什么想法吗？
