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

Question

不太可能UITableViewCell，UICollectionViewCell缺少setEditing:animated:和editing属性。

这是设计吗？苹果是否正在执行其他最佳做法来处理UICollectionView及其单元格中的编辑？

Answer 1

也许这就是你需要：

子类UICollectionViewController像ABCCollectionViewController：

let vc = UINavigationController(rootViewController: ABCCollectionViewController()) 

然后在ABCCollectionViewControllerviewDidLoad：

self.navigationItem.leftBarButtonItem = self.editButtonItem 

然后覆盖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，您可以拨打：

setEditing(true, animated: true) 

Answer 2

如果您正在编辑时改变像allowsMultipleSelection一些国家在UICollectionView：

override func setEditing(_ editing: Bool, animated: Bool) { 
    super.setEditing(editing, animated: animated) 
    collectionView.allowsMultipleSelection = editing 
} 

你可以简单地添加到您的UICollectionViewCell子类：

var isEditing: Bool { 
    return (superview as! UICollectionView).allowsMultipleSelection 
}
