FSView

轻松实现悬浮 Section 的效果。要做列表请使用 FSListView，照片墙类型则使用 FSItemView。

安装

pod 'FSView'

如何使用 FSListView

注册 FSListViewCell

let nib = UINib(nibName: "\(yourCustomCell.self)", bundle: nil)
listView.register(nib, forCellWithReuseIdentifier: "\(yourCustomCell.self)")

设置 headerHeight 及 sectionHeight

listView.headerHeight = 400
listView.sectionHeight = 40

遵循 FSListViewDelegate 及 FSListViewDataSource

func viewForHeaderView(_ listView: FSListView) -> UIView {
  return yourCustomView
}

func viewForPinSectionHeader(_ listView: FSListView) -> UIView {
  return yourCustomView
}

func listView(_ listView: FSListView, numberOfRowsInSection section: Int) -> Int {
    return yourDataCount
}

func listView(_ listView: FSListView, cellForRowAt indexPath: IndexPath) -> FSListViewCell {
    let cell = listView.dequeueReusableCell(cell: yourCustomCell.self, for: indexPath)
    return yourCustomCell
}

func listView(_ listView: FSListView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return listView.automaticDimension
}

如何使用 FSItemView

注册 FSItemViewCell

let nib = UINib(nibName: "\(yourCustomCell.self)", bundle: nil)
itemView.register(nib, forCellWithReuseIdentifier: "\(yourCustomCell.self)")

设置 headerHeight 及 sectionHeight

itemView.headerHeight = 400
itemView.sectionHeight = 40

遵循 FSItemViewDelegate 及 FSItemViewDataSource

func viewForHeaderView(_ itemView:FSItemView) -> UIView {
    return yourCustomView
}

func viewForPinSectionHeader(_ itemView:FSItemView) -> UIView {
    return yourCustomView
}

func itemView(_ itemView: FSItemView, numberOfItemsInSection section: Int) -> Int {
    return yourDataCount
}

func itemView(_ itemView: FSItemView, cellForItemAt indexPath: IndexPath) -> FSItemViewCell {
   let cell = itemView.dequeueReusableCell(cell: yourCustomCell.self, for: indexPath)
    return yourCustomCell
}

func itemView(_ itemView: FSItemView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> FSEdgeInsets {
    return FSEdgeInsets(left: 10, bottom: 0, right: 10)
}

func itemView(_ itemView: FSItemView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    let width = itemView.frame.width / 3 - 15
    return CGSize(width: width, height: width)
}
