UItabelview中的多个UICollection视图,包含 - swift

Question

基本上,我试图获得类似于此结果的东西:http://ashfurrow.com/blog/putting-a-uicollectionview-in-a-uitableviewcell

但是,我想要2个collectionsViews,第一部分为1,第二部分为另一个

我该如何实现这一目标？我在这里抨击我...每次我尝试设置委托和数据源它失败并说我需要注册一个笔尖我也不知道我如何将它的集合视图分开在它的cellForRowAtIndexPath中,我怎么能看到哪个一个正在加载？我怎样才能正确加载它,以便第一部分有self.genre,第二部分有self.radioStat

这是我第二次尝试设置委托和数据源时得到的错误

你需要知道你的哪个(tableView)部分collectionView.一种方法是将UICollectionView子类化并为其添加tvSection属性 - 与Ash Furrow用于AFIndexedCollectionView添加index属性的方式相同.

但是您似乎使用collectionView tag代替他index,大概是为了避免子类化.如果是这样,类似的躲闪就是使用tagtableViewCell contentView来指示单元格所在的部分.修改tableView cellForRowAtIndexPath方法来执行此操作:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier(reuseIdentifier, forIndexPath: indexPath) as UITableViewCell

    if (indexPath.section == 0){
        var cell2: tableViewCellCollectionView = tableView.dequeueReusableCellWithIdentifier(reuseTableViewCellIdentifier, forIndexPath: indexPath) as tableViewCellCollectionView
        cell2.contentView.tag = indexPath.section
        return cell2
    } else if (indexPath.section == 1){
        let cell3: tableViewCellCollectionView2 = tableView.dequeueReusableCellWithIdentifier(reuseTableViewCellIdentifier2, forIndexPath: indexPath) as tableViewCellCollectionView2
        cell3.contentView.tag = indexPath.section
        return cell3
    }
    cell.contentView.tag = indexPath.section
    return cell
}

因为collectionView是作为子视图添加的contentView,所以您可以使用确定给定collectionView的(tableView)部分superview.tag.所以修改你的collectionView cellForItemAtIndexPath来测试这个:

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let section = collectionView.superview.tag
    if section == 0 {
        let cell: collectionViewCellTableView = collectionView.dequeueReusableCellWithReuseIdentifier(reuseCollectionViewCellIdentifier, forIndexPath: indexPath) as collectionViewCellTableView
        // Now configure from the data...
        var rowData: String = self.genre.objectAtIndex(indexPath.row) as String
        cell.title.text = rowData as String
        return cell
    else {
        let cell2: collectionViewCellTableView2 = collectionView.dequeueReusableCellWithReuseIdentifier(reuseCollectionViewCellIdentifier2, forIndexPath: indexPath) as collectionViewCellTableView2
        // Now configure from the data...
        let userPost: String  = self.radioStat.objectAtIndex(indexPath.row) as String
        cell2.pinImage.image = UIImage(named: userPost)
        return cell2
    }
}

这需要一些抛光; 尤其是我不知道你怎么想你的数据(地图sourceArray,genre和radioStat)到的tableView行的CollectionView项目.(我根据你现有的代码猜测了一下).但这应该给你一些工作.
