我将 UICollectionView
放入自定义 UITableView
中。 UICollectionView
框架设置为 contentView
边界,但它并没有完全接受它。
CellForRowAtIndexPath
if indexPath.row == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "collectionViewCell") as! TravelTypeTableViewCell
cell.backgroundColor = .green
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell")!
cell.textLabel?.text = "adsf"
return cell
}
TableViewCell
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
let layout = UICollectionViewFlowLayout()
collectionView = UICollectionView(frame: self.contentView.bounds, collectionViewLayout: layout)
collectionView.delegate = self
collectionView.dataSource = self
collectionView.register(UICollectionViewCell.self, forCellWithReuseIdentifier: "CollectionViewCell")
collectionView.backgroundColor = .clear
self.addSubview(collectionView)
collectionView.leftAnchor.constraint(equalTo: self.contentView.leftAnchor, constant:0).isActive = true
collectionView.rightAnchor.constraint(equalTo: self.contentView.rightAnchor, constant:0).isActive = true
collectionView.topAnchor.constraint(equalTo: self.contentView.topAnchor, constant:0).isActive = true
collectionView.bottomAnchor.constraint(equalTo: self.contentView.bottomAnchor, constant:0).isActive = true
}

最佳答案
如果您使用约束,则无需为 Collection View 提供框架。
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
let layout = UICollectionViewFlowLayout()
let collectionView = UICollectionView(frame: .zero, collectionViewLayout: layout) // no need to give frame as you are adding constraints
collectionView.delegate = self
collectionView.dataSource = self
collectionView.register(UICollectionViewCell.self, forCellWithReuseIdentifier: "CollectionViewCell")
collectionView.backgroundColor = .clear
self.contentView.addSubview(collectionView)
collectionView.leftAnchor.constraint(equalTo: self.contentView.leftAnchor, constant:0).isActive = true
collectionView.rightAnchor.constraint(equalTo: self.contentView.rightAnchor, constant:0).isActive = true
collectionView.topAnchor.constraint(equalTo: self.contentView.topAnchor, constant:0).isActive = true
collectionView.bottomAnchor.constraint(equalTo: self.contentView.bottomAnchor, constant:0).isActive = true
}
关于ios - UICollectionView 的框架未正确更新为 UITableViewCell subview ,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/59854176/
