我正在尝试UIScrollView使用此代码水平绘制列表但无法正常工作？
let nib = UINib(nibName: cellIdentifier, bundle: nil)
collectionView.register(nib, forCellWithReuseIdentifier: cellIdentifier)
collectionView.collectionViewLayout = layout(withParentView: view)
self.collectionView.delegate = self
self.collectionView.dataSource = self
流布局方法
// #PRAGMA mark - UICollectionViewFlowLayout()
func layout(withParentView parentView: UIView) -> UICollectionViewFlowLayout {
let layout = UICollectionViewFlowLayout()
layout.itemSize = CGSize(width: 160, height: 65)
layout.sectionInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
layout.minimumLineSpacing = 0
layout.minimumInteritemSpacing = 0
layout.scrollDirection = .horizontal
return layout
}
这是委托和数据源方法
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 2
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: cellIdentifier, for: indexPath) as! RowCollectionViewCell
if indexPath.row % 2 == 0 {
cell.backgroundColor = UIColor(red: 248/255, green: 248/255, blue: 248/255, alpha: 1)
}else {
cell.backgroundColor = UIColor(red: 1, green: 1, blue: 1, alpha: 1)
}
cell.label.text = "Field\(indexPath.row)"
return cell
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize
{
return CGSize(width: 160, height: 65)
}
当我运行它时，它会显示这个（项目的垂直列表）。有什么我错过的吗。任何帮助，将不胜感激。
