## Example

To run the example project, clone the repo, and run `pod install` from the Example directory first.

## Requirements

## Installation

LBHorizontalCollectionViewLayout is available through [CocoaPods](https://cocoapods.org). To install
it, simply add the following line to your Podfile:

```ruby
pod 'LBHorizontalCollectionViewLayout'

#使用方法
- (UICollectionView *)collectionView
{
    if (!_collectionView) {
        LBHorizontalCollectionViewLayout *layout = [[LBHorizontalCollectionViewLayout alloc] init];
        _collectionView = [[UICollectionView alloc] initWithFrame:CGRectZero collectionViewLayout:layout];
        _collectionView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0);
        ///设置layout 的代理
        layout.delegate = self;
        layout.sectionInset = UIEdgeInsetsMake(0, 0, 10, 0);
        _collectionView.delegate = self;
        _collectionView.dataSource = self;
        [_collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:NSStringFromClass([UICollectionViewCell class])];
        _collectionView.showsHorizontalScrollIndicator = NO;
        if (@available(iOS 10.0, *)) {
            _collectionView.prefetchingEnabled = NO;
        } else {
            // Fallback on earlier versions
        }
        _collectionView.backgroundColor = [UIColor cyanColor];
    }
    return _collectionView;
}

#实现协议方法

#pragma mark - VVGeneralCategoryTopCellLayoutDeledate
- (CGSize)itemSizeForItemInCollectionView:(UICollectionView *)collectionView layout:(LBHorizontalCollectionViewLayout *)collectionViewLayout
{
    return CGSizeMake(CGRectGetWidth(self.view.bounds)/4.5, 97);
}

- (UIEdgeInsets)edgeInsetsForSectionInCollectionView:(UICollectionView *)collectionView layout:(LBHorizontalCollectionViewLayout *)collectionViewLayout
{
    return UIEdgeInsetsMake(10, 0, 0, 0);
}

#计算collectionView的高度 （如果需要计算的话）

LBMutilRowsHorizontalLayoutParameterModel *paramsModel = [[LBMutilRowsHorizontalLayoutParameterModel alloc] init];
paramsModel.itemCount = 50;
paramsModel.itemSize = CGSizeMake(CGRectGetWidth(self.view.bounds)/4.5, 97);
paramsModel.edgeInsetsForSection = UIEdgeInsetsMake(10, 0, 0, 0);
paramsModel.boundWidthSubtractContentInset = CGRectGetWidth(self.view.bounds);
CGFloat height = [LBHorizontalCollectionViewLayout heightOffContentWithLayoutParamsModel:paramsModel];
self.collectionView.frame = CGRectMake(0, 100, CGRectGetWidth(self.view.bounds), height);
