与标题重叠的不可开发的 CollectionViewCells [Swift]

【中文标题】与标题重叠的不可开发的 CollectionViewCells [Swift]

【英文标题】：Untappable CollectionViewCells Which Overlaps Header [Swift]

【问题描述】：

如标题所述，实际上我对点击区域有疑问。我所做的是使用自定义UICollectionViewFlowLayout 中的SectionInset 将单元格与标题重叠，因此它看起来像图片上所述。

问题是，你可以看到那里的红色圆圈和绿色圆圈，它代表不能点击，可以点击。我已经搜索了一整天，但没有找到答案。

我有什么遗漏的吗？

ViewDidLoad中的单元格插入代码：

let layout: FlowLayoutProperty = FlowLayoutProperty.init(itemSize: CGSize.zero, minimumInteritemSpacing: 10, minimumLineSpacing: 10)
        layout.scrollDirection = UICollectionView.ScrollDirection.vertical
        layout.sectionInset = UIEdgeInsets.init(top: -50, left: 10, bottom: 10, right: 10)

标题代码为：

func collectionView(_ collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, at indexPath: IndexPath) -> UICollectionReusableView 
    
    //header height size, refer headerreferencesize
    
    switch kind 
        case UICollectionView.elementKindSectionHeader:
            
            guard let headerView: V4UMGCMainHeader = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: "V4UMGCMainHeaderWeather", for: indexPath) as? V4UMGCMainHeader else 
                fatalError("Header not found")
            
            
            self.headerView = headerView
            
            let dFormat: DateFormatter = DateFormatter.init()
            dFormat.dateFormat = "EE, dd MMM"
            headerView.lblUMGCWDate.text = dFormat.string(from: Date.init())
            
            headerView.btnUMGCWAddMember.transformToContentStandard()
            headerView.btnUMGCWAddMember.titleLabel?.font = FontPredefine.MuliMedium(withSize: 12.0)
            headerView.btnUMGCWAddMember.backgroundColor = UIColor.hexStringToUIColor(hex: "#C18845")
            headerView.btnUMGCWAddMember.addTarget(self, action: #selector(self.checkMemberShipHeader(sender:)), for: UIControl.Event.touchUpInside)
            
            headerView.lblUMGCWLocation.text = "Point Location"
            
            if(KeychainedLoginCache.loadClubMemberInfo()[.ClubHouseID]! == nil && self.menuType == MenuType.UserMode)
            
                //if clubmember not available
                headerView.btnUMGCWAddMember.setTitle(AppDelegate.getLocalString(forKey: "UMGCVC_CLUBHEADER_ADDMEMBER_BTN"), for: UIControl.State.normal)
                headerView.btnUMGCWAddMember.isEnabled = true
                headerView.lcUMGCWAddMemberHeight.constant = 40
                self.headerLayoutProperty?.sectionInset = UIEdgeInsets.init(top: -50, left: 10, bottom: 10, right: 10)
            
            else
            
                //if clubmember available
                headerView.btnUMGCWAddMember.setTitle("", for: UIControl.State.normal)
                headerView.btnUMGCWAddMember.isEnabled = false
                headerView.lcUMGCWAddMemberHeight.constant = 0
                self.headerLayoutProperty?.sectionInset = UIEdgeInsets.init(top: -90, left: 10, bottom: 10, right: 10)
            
       
            
        return headerView
        
    default:
        assert(false, "error")
        
    
    return V4UMGCMainHeader.init()

【参考方案1】：

好的，我认为这真的很棘手。我应该把zIndex 放在UICollectionViewFlowLayout 下layoutAttributesForElements 和layoutAttributesForItem 下，现在可以了。
