//引入头部视图 -(UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath { UICollectionReusableView *reusableview = nil; NSLog(@"kind = %@", kind); if (kind == UICollectionElementKindSectionHeader){ CouponCollHeaderView *headerV = (CouponCollHeaderView *)[collectionView dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:CellHeadID forIndexPath:indexPath]; headerV.backgroundColor = [UIColor greenColor]; [headerV getSHCollectionReusableViewHearderTitle:@"这是标题"]; reusableview = headerV; } return reusableview; } //设置头部高度 -(CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout referenceSizeForHeaderInSection:(NSInteger)section{ return CGSizeMake(SCREEN_WIDTH, CONVER_VALUE(245.5f)); }
剩下的后期整理。
