缺少编辑属性和setEditing:animated:在UICollectionViewCell中

Question

不太可能UITableViewCell,UICollectionViewCell缺乏setEditing:animated:和editing属性.

这是设计的吗？Apple是否在UICollectionView及其单元格中执行其他最佳实践来处理编辑？

Answer 1

也许这就是您所需要的：

UICollectionViewController 子类如下ABCCollectionViewController：

let vc = UINavigationController(rootViewController: ABCCollectionViewController())

然后viewDidLoad在ABCCollectionViewController：

self.navigationItem.leftBarButtonItem = self.editButtonItem

然后重写 setEditting 方法：

override func setEditing(_ editing: Bool, animated: Bool) {
    super.setEditing(editing, animated: true)

    // Use these methods to do the edit things, without test but should works
    collectionView?.beginInteractiveMovementForItem(at: indexPath)
    print("editting")//Do some edit thing
    collectionView?.endInteractiveMovement()  
    collectionView.updateInteractiveMovementTargetPosition()
    collectionView?.cancelInteractiveMovement()
}

然后你可以调用：

setEditing(true, animated: true)
