为应对类似淘宝首页,京东首页,国美首页的复杂布局而写的多样化的UICollectionView。
目前支持标签布局,列布局,百分比布局,定位布局等。可以根据不同的section设置不同的布局。实现了电影选座等高难度的布局。

如在使用中有bug欢迎反馈,如果有愿意帮我完善源代码的也十分感谢。

导入

支持cocoapod导入

pod 'ZLCollectionViewFlowLayout' 

如果遇到以下错误,
Unable to find a specification for ZLCollectionViewFlowLayout
请使用pod update命令来安装。

用法

//在UICollectionView创建之前加入ZLCollectionViewFlowLayout

- (UICollectionView*)collectionViewLabel {
    if (!_collectionViewLabel) {
        ZLCollectionViewFlowLayout *flowLayout = [[ZLCollectionViewFlowLayout alloc] init];
        flowLayout.delegate = self;

        _collectionViewLabel = [[UICollectionView alloc]initWithFrame:self.view.bounds collectionViewLayout:flowLayout];
        _collectionViewLabel.dataSource = self;
        _collectionViewLabel.delegate = self;
        _collectionViewLabel.backgroundColor = [UIColor whiteColor];
        [_collectionViewLabel registerClass:[SEMyRecordLabelCell class] forCellWithReuseIdentifier:[SEMyRecordLabelCell cellIdentifier]];
        [_collectionViewLabel registerClass:[SEMyRecordHeaderView class] forSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:[SEMyRecordHeaderView headerViewIdentifier]];
    }
    return _collectionViewLabel;
}

//实现代理,如果不实现也可以自己直接设置self.sectionInset,self.minimumLineSpacing,self.minimumInteritemSpacing。但是这种设置不支持不同section不同数值

//指定section用的样式。LabelLayout是标签样式,ClosedLayout用于tableviewcell或者瀑布流,九宫格之类的。
