来自 nib 的 table 视图单元格中的集合视图

Question

任何人都可以告诉我，如何在 table 来自 nib 的视图单元格中使用集合视图。我有 Table 视图、自定义 table 视图单元格、集合视图、自定义集合视图单元格。在 table 视图的委托方法中，我添加了

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
        static NSString *cellId  = @"cell";

        CreateStoryTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellId];
        if (cell == nil) {
            NSArray  *nib = [[NSBundle mainBundle] loadNibNamed:@"CreateStoryTableViewCell" owner:self options:nil];
            cell = [nib objectAtIndex:0];
        }

        [cell.collectionviwStory registerNib:[UINib nibWithNibName:@"StoryPicsCollectionViewCell" bundle:nil] forCellWithReuseIdentifier:@"StoryPicsCollectionViewCell"];
        cell.collectionviwStory.dataSource=self;
        cell.collectionviwStory.delegate=self;

        // Configure layout
        UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init];
        [flowLayout setItemSize:CGSizeMake(100.0, 100.0)];
        [flowLayout setScrollDirection:UICollectionViewScrollDirectionHorizontal];
        [self setAutomaticallyAdjustsScrollViewInsets:NO];

        [cell.collectionviwStory setCollectionViewLayout:flowLayout];

        return cell;

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

    static NSString *identifier = @"StoryPicsCollectionViewCell";


    static BOOL nibMyCellloaded = NO;

    if(!nibMyCellloaded)
    {
        UINib *nib = [UINib nibWithNibName:@"StoryPicsCollectionViewCell" bundle: nil];
        [collectionView registerNib:nib forCellWithReuseIdentifier:identifier];
        nibMyCellloaded = YES;
    }

    StoryPicsCollectionViewCell *cell = (StoryPicsCollectionViewCell *)[collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
    cell.backgroundColor = [UIColor greenColor];

    return cell;
}

在我的自定义 table 单元格中

- (void)awakeFromNib {
    // Initialization code
    UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc] init];
    layout.sectionInset = UIEdgeInsetsMake(10, 10, 9, 10);
    layout.itemSize = CGSizeMake(44, 44);
    layout.scrollDirection = UICollectionViewScrollDirectionHorizontal;
    [self.collectionviwStory registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:CollectionViewCellIdentifier];
    self.collectionviwStory.backgroundColor = [UIColor greenColor];
    self.collectionviwStory.showsHorizontalScrollIndicator = NO;
    [self.contentView addSubview:self.collectionviwStory];

}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}



-(void)layoutSubviews
{
    [super layoutSubviews];

    self.collectionviwStory.frame = self.contentView.bounds;
}

- (void)setCollectionViewDataSourceDelegate:(id<UICollectionViewDataSource, UICollectionViewDelegate>)dataSourceDelegate indexPath:(NSIndexPath *)indexPath
{
    self.collectionviwStory.dataSource = dataSourceDelegate;
    self.collectionviwStory.delegate = dataSourceDelegate;
    [self.collectionviwStory reloadData];
}

我的代码在

崩溃了

 StoryPicsCollectionViewCell *cell = (StoryPicsCollectionViewCell *)
[
 collectionView dequeueReusableCellWithReuseIdentifier:identifier 
 forIndexPath:indexPath
];

谁能帮我解决这个问题？或者为此推荐一些教程

Answer 1

您需要将此代码放在自定义 Table 单元格的 awakeFromNib: 中

    UINib *nib = [[UINib nibWithNibName:@"StoryPicsCollectionViewCell" bundle:[NSBundle mainBundle]];
    [self.collectionviwStory registerNib:nib forCellWithReuseIdentifier:@"StoryPicsCollectionViewCell"];

现在你的双端队列调用发生在你有机会注册你的 nib 之前。试试这个希望它会有所帮助。
