UICollectionView 为每个section 添加headerview
这个问题我纠结了好长时间,网上关于UICollection的事例很少,这个也是我google找了许久找到的方法(原谅我的愚蠢),留下权作备份,如果对你有帮助的话,更好!
如果有错得地方,还请多指教!我也是刚学习UICollection!
//注册headercell [self.PhotoAlbumCollection registerNib:[UINib nibWithNibName:@"MMCollectionHeaderView" bundle:nil] forSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:@"headercell"];
- (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath { if (kind == UICollectionElementKindSectionHeader) { MMCollectionHeaderView *headercell = [collectionView dequeueReusableSupplementaryViewOfKind:kind withReuseIdentifier:@"headercell" forIndexPath:indexPath]; NSDictionary *dic = datasource[indexPath.section]; return headercell; }else { return nil; } }
再说下MMCollectionHeaderView ,改类继承UICollectionReusableView 即:@interface MMCollectionHeaderView : UICollectionReusableView
