UICollectionView中的自定义标题，带有没有Storyboard的Interface Builder [英] Custom Header in UICollectionView with Interface Builder without Storyboard

问题描述

我正在尝试将自定义视图添加到 UICollectionView 的标题部分。我有xib文件界面构建器，但我不使用storyboard。我已经检查了Interface Builder中的Section Header，但是没有出现任何UICollectionReusableView，我该怎么办？

I'm trying to add a custom view to the header section of my UICollectionView. I have the xib file interface builder but I don't use storyboard. I have checked the Section Header in Interface Builder but doesn't appear any UICollectionReusableView, what can I do?

推荐答案

最简单的解决方案要以编程方式执行（并将HeaderReusableView保存在另一个XIB文件中）：

The easiest solution is to do is programatically (and keep your HeaderReusableView in another XIB file):

[self.collectionView registerNib:[UINib nibWithNibName:@"ItemHeaderView" bundle:nil]
          forSupplementaryViewOfKind:UICollectionElementKindSectionHeader
                 withReuseIdentifier:kItemSectionHeaderViewID];

然后：

- (CGSize) collectionView:(UICollectionView *)collectionView
                   layout:(UICollectionViewLayout *)collectionViewLayout
referenceSizeForHeaderInSection:(NSInteger)section {
    return CGSizeMake(60.0f, 30.0f);// width is ignored
}

当然：

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

    NSString *productId = nil; ///

    ItemHeaderView *view = nil;

    view = [collectionView dequeueReusableSupplementaryViewOfKind:kind
                                       withReuseIdentifier:kItemSectionHeaderViewID
                                              forIndexPath:indexPath];

    view.titleLabel.text = productId;

    view.backgroundColor = [UIColor yellowColor];

    return view;
}
