GXWaterCollectionViewLayout 是一個好用的瀑布流布局，可以設(shè)置縱橫方向和排列數(shù)等。

Requirements

• iOS 7.0 or later

• Xcode 8.0 or later

Usage in you Podfile:

pod?'GXWaterCollectionViewLayout'

?

可以設(shè)置縱橫方向

@property?(nonatomic,?assign)?UICollectionViewScrollDirection?scrollDirection;??//滾動方向

可以設(shè)置的其它參數(shù)

@property?(nonatomic,?assign)?NSInteger????numberOfColumns;???//瀑布流橫排數(shù)
@property?(nonatomic,?assign)?CGFloat??????lineSpacing;???????//縱向間距
@property?(nonatomic,?assign)?CGFloat??????interitemSpacing;??//橫向間距
@property?(nonatomic,?assign)?CGSize???????headerSize;????????//頁眉尺寸
@property?(nonatomic,?assign)?CGSize???????footerSize;????????//頁腳尺寸
@property?(nonatomic,?assign)?UIEdgeInsets?sectionInset;??????//分類inset

實(shí)例應(yīng)用代碼

//?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
