CKComponentKit CollectionView问题

Question

我目前正在尝试使用ComponentKit，我遇到了问题。我想使用我在主视图上创建的CKCollectionView。当我在我的MainView（包含ScrollView）中将CKCollectionView放到其容器中时，我遇到了2个问题。第一个，如果我手动创建CollectionView的框架，这里它给了我。（蓝色方块是＆＃34; UICollectionViewControllerWrapperView＆＃34;）

但是，我真正想做的是使用砌体和约束设置框架，允许我将框架设置为等于其容器（黄色方框）。但是当我这样做时，它会用空单元格填充整个蓝色矩形高度，如下图所示：

所以看起来我的实际单元格（或组件）的大小为647并且它们引起了问题。但是此时我迷失了，并且想知道是否有人之前有过类似的问题:)。

这是我的代码：

创建单元格的实际组件：

@implementation SSOUpcomingAuctionComponent


+ (instancetype)newWithProduct:(Product *)product {

    SSOProductHeaderComponent *head = [SSOProductHeaderComponent newWithTitle:product.time];
    SSOProductPictureComponent *body = [SSOProductPictureComponent newWithImage:product.image];
    SSOProductShareComponent *footer = [SSOProductShareComponent newWithPrice:product.price];

    return [super newWithComponent:[CKInsetComponent newWithInsets:UIEdgeInsetsMake(0, 0, 0, 0)
                                                         component:[CKStackLayoutComponent newWithView:{
                                                             [UIView class], {
                                                                 { @selector(setBackgroundColor:), [UIColor whiteColor] }
                                                                 , { CKComponentViewAttribute::LayerAttribute(@selector(setCornerRadius:)), @6.0 }
                                                                 , { @selector(setClipsToBounds:), @YES }
                                                             }
                                                         } size:{}
                                                        style:{
                                                             .alignItems = CKStackLayoutAlignItemsCenter, .direction = CKStackLayoutDirectionVertical,
                                                             .spacing = 2
                                                         } children:{{
                                                                         head,
                                                                     },
                                                                     {body},
                                                                     {footer}}]]];
}

    [self addChildViewController:self.upcomingAuctionsVC];

    [self.bottomView addSubview:self.upcomingAuctionsVC.view];

    [self.upcomingAuctionsVC didMoveToParentViewController:self];
