以后封装任务: 1.装饰视图的增加。

安装

CocoaPods

  1. 将 cocoapods 更新至最新版本.
  2. 在 Podfile 中添加 pod "SYStickHeaderWaterFall"
  3. 执行 pod installpod update

(usage) 用法

(init and set delegate) 初始化并设置delegate:

SYStickHeaderWaterFallLayout *cvLayout = [[SYStickHeaderWaterFallLayout alloc] init];

cvLayout.delegate = self;

(set property) 设置属性:

//是否设置sectionHeader停留,默认YES

cvLayout.isStickyHeader = YES;

//是否设置Footer停留,默认NO

cvLayout.isStickyFooter = NO;

//section停留的位置是否包括原来设置的top,默认NO

cvLayout.isTopForHeader = YES;

//当你用UINavigationController和UITabbarViewController并设置一些属性时,collectionview的展示视图的坐标y会变得很奇怪,那就在此修正,默认64

cvLayout.fixTop = 64.0f;

(implement delegate method) 实现代理方法:

// 返回所在section的每个item的width(一个section只有一个width)

- (CGFloat)collectionView:(nonnull UICollectionView *)collectionView
               layout:(nonnull SYStickHeaderWaterFallLayout *)collectionViewLayout
widthForItemInSection:( NSInteger )section;

// 返回所在indexPath的每个item的height(每个item有一个height,要不然怎么是瀑布流😄

- (CGFloat)collectionView:(nonnull UICollectionView *)collectionView
               layout:(nonnull SYStickHeaderWaterFallLayout *)collectionViewLayout
heightForItemAtIndexPath:(nonnull NSIndexPath *)indexPath;

@optional

// 返回所在indexPath的header的height

- (CGFloat) collectionView:(nonnull UICollectionView *)collectionView
                layout:(nonnull SYStickHeaderWaterFallLayout *)collectionViewLayout
heightForHeaderAtIndexPath:(nonnull NSIndexPath *)indexPath;

// 返回所在indexPath的footer的height

- (CGFloat) collectionView:(nonnull UICollectionView *)collectionView
                layout:(nonnull SYStickHeaderWaterFallLayout *)collectionViewLayout
heightForFooterAtIndexPath:(nonnull NSIndexPath *)indexPath;

// 返回所在section与上一个section的间距(表达的可能不够准确,但是你们都懂的)

- (CGFloat) collectionView:(nonnull UICollectionView *)collectionView
                layout:(nonnull SYStickHeaderWaterFallLayout *)collectionViewLayout
topInSection:(NSInteger )section;

// 返回所在section与下一个section的间距(表达的可能不够准确,但是你们都懂的)

- (CGFloat) collectionView:(nonnull UICollectionView *)collectionView
                layout:(nonnull SYStickHeaderWaterFallLayout *)collectionViewLayout
        bottomInSection:( NSInteger)section;

// 返回所在section的header停留时与顶部的距离(如果设置isTopForHeader = yes ,则距离会叠加)

- (CGFloat) collectionView:(nonnull UICollectionView *)collectionView
                layout:(nonnull SYStickHeaderWaterFallLayout *)collectionViewLayout
       headerToTopInSection:( NSInteger)section;
