GXWaterCollectionViewLayout 是一个好用的瀑布流布局，可以设置纵横方向和排列数等。
Requirements
-
iOS 7.0 or later
-
Xcode 8.0 or later
Usage in you Podfile:
pod 'GXWaterCollectionViewLayout'
可以设置纵横方向
@property (nonatomic, assign) UICollectionViewScrollDirection scrollDirection; //滚动方向
可以设置的其它参数
@property (nonatomic, assign) NSInteger numberOfColumns; //瀑布流横排数 @property (nonatomic, assign) CGFloat lineSpacing; //纵向间距 @property (nonatomic, assign) CGFloat interitemSpacing; //横向间距 @property (nonatomic, assign) CGSize headerSize; //页眉尺寸 @property (nonatomic, assign) CGSize footerSize; //页脚尺寸 @property (nonatomic, assign) UIEdgeInsets sectionInset; //分类inset
实例应用代码
// 初始化瀑布流布局 self.waterLayout = [[GXWaterCollectionViewLayout alloc] init]; self.waterLayout.numberOfColumns = 4; self.waterLayout.lineSpacing = 10.0; self.waterLayout.interitemSpacing = 10.0; self.waterLayout.sectionInset = UIEdgeInsetsMake(20, 20, 20, 20); self.waterLayout.scrollDirection = UICollectionViewScrollDirectionVertical; self.waterLayout.headerSize = CGSizeMake(self.view.bounds.size.width, 40); self.waterLayout.footerSize = CGSizeMake(self.view.bounds.size.width, 40); self.waterLayout.delegate = self; // 初始化UICollectionView self.waterCollectionView = [[UICollectionView alloc] initWithFrame:self.view.bounds collectionViewLayout:self.waterLayout]; self.waterCollectionView.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight; self.waterCollectionView.backgroundColor = [UIColor whiteColor]; self.waterCollectionView.delegate = self; self.waterCollectionView.dataSource = self; [self.view addSubview:self.waterCollectionView];
方向UICollectionViewScrollDirectionVertical效果
