Question

我已经看到很多方法可以在UICollectionView中获取轮播/一行/节。但非工作可能，你有办法。

我有以下内容：

@IBAction func openCollectionView(_ sender: Any) {
    let layout = UICollectionViewFlowLayout()
    layout.scrollDirection = .horizontal
    layout.itemSize = CGSize(width: 50, height: self.view.frame.height)
    collectionView = UICollectionView(frame: self.view.frame, collectionViewLayout: layout)

    collectionView!.delegate   = self
    collectionView!.dataSource = self
    collectionView!.register(PDCollectionViewCell.self, forCellWithReuseIdentifier: "cellIdentifier")

    collectionView?.contentOffset.x = 20

    collectionView?.reloadData()
    collectionView?.layoutIfNeeded()

    collectionView!.addBlurEffect()
    self.view.addSubview(collectionView!)

}

好的 - 足够简单：

layout.itemSize = CGSize(width: (self.view.frame.size.width/2)+50, height: (self.view.frame.size.height/2)+50)

对于更复杂的细胞：

func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
    return CGSize(width: 100, height: 100)
}

UICollectionViewFlowLayout一行/一段水平
