在水平滚动中顶部具有不同高度的集合视图Pin单元格

Question

I have a horizontal collection view with different cell heights. By default the cells are centered in the middle of the collection view.

What I need is pin them to the top of the collection view not in the center so the extra space will be beneath the cells.

I have only one row with a total of 4 cells.

Answer 1

I have found the solution. Simply add this code in cellForItem method .

cell.frame = CGRect(origin: CGPoint(x: cell.frame.minX, y: 0), size: cell.frame.size)

Also

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    collectionView.reloadData()
}
