Question

我创建了一个自定义xib，我的目标是在集合视图中将其显示为如下图所示：

我设置了我的集合视图：

收藏查看标题

Sub main()
  .
  .
  .
  Dim origFileList as Collection
  dirfilename = Dir(strfilename & "\")
  While dirfilename <> ""
    origFileList.add(dirfilename)
    dirfilename=Dir()
  End While
  'Make a backup of all the .msg files
  MkDir(strfilename & "\backUP")
  FileCopy(strfilename & "\*.msg", strfilename & "\backUP\.")
  'Do the loop for all files in a folder
  For Each dirfilename in origFileList
    If InStr(1, dirfilename, ".xls", vbBinaryCompare) > 0 Then
      update_Excel_files strfilename, dirfilename, mistakes_table_name, counter
    ElseIf InStr(1, dirfilename, ".msg", vbBinaryCompare) > 0 Then
      update_Emails strfilename, dirfilename, mistakes_table_name, counter
    End If
    dirfilename = Dir
  Next dirfilename
  .
  .
  'MAKE SURE YOU CLEAN UP AT THE END OF MAIN SUB
  Kill(strfilename & "\backUP\*.*")
  RmDir(strfilename & "\backUP")
End Sub

Sub update_Emails(strfilename As String, dirfilename As String, mistakes_table_name As String, counter As Integer)
  .
  'HERE YOU CAN USE DIR as NOW IT WILL NOT INTERFERE WITH Dir State in main
  .
  'PROCESS ON .MSG FILES FROM <<strfilename & "\backUP">>
  .
  .
  .
End Sub

数据来源

+(id)newTitleView
 {
VideoCollectionViewTitleView* vidcollectionTitleView = [[[NSBundle mainBundle] loadNibNamed:@"ProductCollectionViewTitleView" owner:nil options:nil] lastObject];

if ([vidcollectionTitleView isKindOfClass:[VideoCollectionViewTitleView class]])
{
    return vidcollectionTitleView;
}
else
{
    return nil;
}
}

这就是我将对象添加到数据源的方式：

-(instancetype)initWithVideos:(Videos *)videos
  {
    self = [super init];
    if (self)
   {
    _videos = videos;
   }
return self;
}

-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{

return _videos.content.count ;

}


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

Video *video = [self.videos content][indexPath.row];
VideoCollectionViewCell *cell = [collectionView  dequeueReusableCellWithReuseIdentifier:kGENERIC_COLLECTION_CELL_ID forIndexPath:indexPath];


for (int cnt = 0; cnt <[[video youtube]count]; cnt++) {

    NSMutableString *youtubeImageString = [[NSMutableString   alloc]initWithString:kYOUTUBE_IMAGE_URL];

    [youtubeImageString replaceOccurrencesOfString:@"videoId" withString: [video youtube][cnt++] options:0 range:NSMakeRange(0, youtubeImageString.length-1)];
    NSLog(@"check the url %@", youtubeImageString);

    [cell.imageView sd_setImageWithURL:[NSURL URLWithString:youtubeImageString]
                      placeholderImage:nil
                             completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
                                 if (cacheType != SDImageCacheTypeMemory)
                                 {
                                     cell.imageView.alpha = 0.0;
                                     double val = ((double)arc4random()/ARC4RANDOM_MAX)*0.8;
                                     [UIView animateWithDuration:0.2 delay:val options:UIViewAnimationOptionCurveEaseInOut animations:^{
                                         cell.imageView.alpha = 1.0;
                                     } completion:nil];
                                 }

                             }];

    //set labels

    [cell.nameLabel setText:@"Videoooos"];

}

return cell;
}

这是我得到的结果：

当我提出一个断点时：VideoCollectionViewTitleViewDataSource *dataSource = [[VideoCollectionViewTitleViewDataSource alloc]initWithVideos:self.model.videos]; [self.collectionViewDataSourceArray addObject:dataSource];这就是我得到的：

正如你所看到的那样，只有一个项目，但我的数组中有多个项目，对于我在这里做错了什么的任何建议都会非常感激，因为我坚持这个。

Video.Content [] Youtube []：

[type]：视频      [内容] :(          “\ n [youtube] :( \ n 4Cw856cbyNI，\ n GcmEqI9fpYo，\ n L7xR42O825Q，\ n kZem01RQOeQ，\ n
  L7xR42O825Q，\ n \“swgU9Q-8aEA \”，\ n \“v_joMRl6wus \”，\ n
  tKwSgFo0Dz8，\ n \“Rg2C-9QJmN0 \”，\ n \“UEW3EYc_aKE \”\ n
  ）\ n“）

视频类：

[self.collectionViewDataSourceArray addObject:dataSource];

视频类

    @interface Videos : JSONModel

@property (strong, nonatomic) NSString *title;
@property (strong, nonatomic) NSString *type;
@property (strong, nonatomic) NSString *display;
@property (strong, nonatomic) NSArray <Video> *content;

注意：我已经查看过：Link 1，但在我的情况下它没用。

Answer 1

1.let cellReuseIdentifier：String =“cellName”。

2. @ IBOutlet weak var myCollectionView：UICollectionView？

3.var nibName = UINib（nibName：cellReuseIdentifier，bundle：nil） myCollectionView？.register（nibName，forCellWithReuseIdentifier：cellReuseIdentifier）

4.let cell = collectionView.dequeueReusableCell（withReuseIdentifier：cellReuseIdentifier，for：indexPath as IndexPath）as！ MyCollectionViewCell

UICollectionView不返回所有单元格
