标题: ios - 在另一个 Collection View 的单元格内插入 Collection View
我正在尝试实现一个水平和垂直滚动都可以工作的 View 。为此，我采用了 Main Collection View 。我把它的布局设置为水平的。在该 Collection View 的单元格中，我采用了另一个 Collection View ，我将其布局视为垂直。当我尝试运行它时，它会给出错误

Best Answer-推荐答案
看到Collectionview变成一个CollectionView单元格会是这样的
protocol FlashDealCollectionViewCellDelegate:NSObjectProtocol {
func onFlashDealItemClicked();
}
class FlashDealCollectionViewCell: UICollectionViewCell ,
UICollectionViewDelegate, UICollectionViewDelegateFlowLayout,
UICollectionViewDataSource{
//for handle click event using delegate
weak var delegate: FlashDealCollectionViewCellDelegate?
override func awakeFromNib() {
super.awakeFromNib()
serInnerCollectionView()
}
func serInnerCollectionView() {
flashDealCollectionView.delegate = self
flashDealCollectionView.dataSource = self
flashDealCollectionView.register(UINib(nibName:
"FlashDealItemView", bundle: nil), forCellWithReuseIdentifier:
"flashdealitem")
}
func collectionView(_ collectionView: UICollectionView,
numberOfItemsInSection section: Int) -> Int {
return 25
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt
indexPath: IndexPath) -> UICollectionViewCell {
let m:FlashDealItemCollectionViewCell =
collectionView.dequeueReusableCell(withReuseIdentifier:
"flashdealitem", for: indexPath) as! FlashDealItemCollectionViewCell
return m;
}
func collectionView(_ collectionView: UICollectionView, layout
collectionViewLayout: UICollectionViewLayout, sizeForItemAt
indexPath: IndexPath) -> CGSize {
let width = 80;
return CGSize(width: width+10, height: 100);
}
func collectionView(_ collectionView: UICollectionView,
didSelectItemAt indexPath: IndexPath) {
guard let delegate = delegate else {
return
}
//Handle click event
delegate.onFlashDealItemClicked()
}
