ios - 如何设置 UICollectionView 填充 UIEdgeInsets

Question

你好，我有 UIControllerView ，我用下面的代码设置了 UIEdgeInsets；

  self.automaticallyAdjustsScrollViewInsets = false
  self.collectionView.contentInset = UIEdgeInsets(top: 10, left: 10, bottom: 100, right: 10)

我的 ContentView 代码

 let contentWidth = maxWidthInASection
    let contentHeight = Double(collectionView!.numberOfSections())
    self.contentSize = CGSize(width: Double(contentWidth), height: contentHeight)
    self.contentSize.height = CGFloat(Double(collectionView!.numberOfSections()))

但是不起作用，用户没有选择底部 cells，因此当用户自动滚动到底部单元格时，我需要添加底部填充大小 50- 100 px，例如空白区域。

第二个是;

When users scrolling collection view cells after collection view goes first opened position i want to disable it if user touch and move collection view anywhere must be stay there dont be goes firstly position ?

我下面的示例图片用于底部填充

我该怎么做？

谢谢!

Answer 1

 let flow: UICollectionViewFlowLayout = CollectionView.collectionViewLayout as! UICollectionViewFlowLayout
     flow.sectionInset = UIEdgeInsetsMake(70, 0, 0, 0)
