是否一定要自定义layout？
O(∩_∩)O 你把轮播图那个View
[self.collectionView registerClass:[lunboView class] forSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:findCollectionViewSectionHeaderIdentifier];
其中lunboView继承与UICollectionReusableView
- (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath
{
lunboView *headerView = [collectionView dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:findCollectionViewSectionHeaderIdentifier forIndexPath:indexPath];
}
你把你的轮播View加到新建的那个View中就行了
