CollectionView Header And footer 的添加和设置

建议先看CollectionView 第一篇：http://www.jianshu.com/p/a1614404ae96

注册Header 和 Footer

    //注册区头

        [_myCollectionView registerClass:[HeaderCRView class] forSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:@"headerView"];

   //注册区尾

        [_myCollectionView registerClass:[HeaderCRView class] forSupplementaryViewOfKind:UICollectionElementKindSectionFooter withReuseIdentifier:@"footerView"];

自定义Header子类  ---->HeaderCRView （创建）

自定义的话，header子类要继承自 UICollectionReusableView。

#pragma mark 自定义区头  区尾 样式

- (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath

{

    NSString *CellIdentifier = @"headerView";

    NSString *cellfooter = @"footerView";

    HeaderCRView *cell= nil;

    if ([kind isEqualToString:UICollectionElementKindSectionHeader]) {

         cell = (HeaderCRView *)[collectionView dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:CellIdentifier forIndexPath:indexPath];

        [cell initCollectionHeaderViewindex:indexPath.section];

    }

     if ([kind isEqualToString:UICollectionElementKindSectionFooter]) {

         cell = (HeaderCRView *)[collectionView dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionFooter withReuseIdentifier:cellfooter forIndexPath:indexPath];

        [cell initCollectionFootViewindex:indexPath.section];

    }

    return cell;

}

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout referenceSizeForHeaderInSection:(NSInteger)section {

        //设置区头高度

    if (section == 0) {

        CGSize size = CGSizeMake(kUIScreenWidth, 135+35);

        return size;

    }

    CGSize size = CGSizeMake(kUIScreenWidth, 35);

    return size;

}

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout referenceSizeForFooterInSection:(NSInteger)section {

    //设置区尾 高度

    CGSize size = CGSizeMake(kUIScreenWidth, 10);

    return size;

}

HeaderCRView  .h

@interface HeaderCRView : UICollectionReusableView

//区头

- (void)initCollectionHeaderViewindex:(NSInteger *)index;

//区尾

- (void)initCollectionFootViewindex:(NSInteger *)indexPath;

@end

HeaderCRView  .m

- (void)initCollectionHeaderViewindex:(NSInteger *)index {

    if (index == 0) {

        UIView *headerView = [[UIView alloc]initWithFrame:CGRectMake(0, 135, kUIScreenWidth, 35)];

        headerView.backgroundColor = [UIColor whiteColor];

        [self addSubview:headerView];

        UILabel *titleLab = [[UILabel alloc]initWithFrame:CGRectMake(15, 10, 80, 15)];

        titleLab.text = @"我的应用";

        titleLab.textColor = [CommonFunctions colorWithHex:0x4A4A4A];

        titleLab.font = [UIFont fontWithName:kPingFang_Regular size:14];

        [headerView addSubview:titleLab];

    }

    if (index == 1) {

        UIView *headerView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, kUIScreenWidth, 35)];

        headerView.backgroundColor = [UIColor whiteColor];

        [self addSubview:headerView];

        UILabel *titleLab = [[UILabel alloc]initWithFrame:CGRectMake(15, 10, 80, 15)];

        titleLab.text = @"业务发展";

        titleLab.textColor = [CommonFunctions colorWithHex:0x4A4A4A];

        titleLab.font = [UIFont fontWithName:kPingFang_Regular size:14];

        [headerView addSubview:titleLab];

    }

}

- (void)initCollectionFootViewindex:(NSInteger *)indexPath {

    UIView *footView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, kUIScreenWidth, 10)];

    footView.backgroundColor = [UIColor groupTableViewBackgroundColor];

    [self addSubview:footView];

}
