UICollectionView(集合视图)增加段头段尾

首先自定义段头类

@interface MyFooterView : UICollectionReusableView

在.m中实现初始化,段尾同理

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        
        self.backgroundColor = [UIColor clearColor];
        
        _titleLab = [[UILabel alloc]init];
        _titleLab.frame = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height-10);
        _titleLab.textAlignment = NSTextAlignmentCenter;
        _titleLab.backgroundColor = [UIColor yellowColor];
        [self addSubview:_titleLab];
        
    }
    return self;
}

创建collectionview注册cell的同时注册段头,段尾同理

   [self.NewgoodsCV registerClass:[MyHeaderView class] forSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:@"HeaderView"];

在代理方法中设置�段头段尾

//设置头尾部内容
-(UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath
{
    UICollectionReusableView *reusableView = nil;
    
    if (kind == UICollectionElementKindSectionHeader) {
        //定制头部视图的内容
        MyHeaderView *headerV = (MyHeaderView *)[collectionView dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:@"HeaderView" forIndexPath:indexPath];
        headerV.titleLab.text = @"段头";
        reusableView = headerV;
    }
//定制尾部视图的内容
    if (kind == UICollectionElementKindSectionFooter){
        MyFooterView *footerV = (MyFooterView *)[collectionView dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionFooter withReuseIdentifier:@"FooterView" forIndexPath:indexPath];
        footerV.titleLab.text = @"段尾";
        reusableView = footerV;
    }
    return reusableView;
}
