编辑点击的 CollectionViewCell

Edit tapped CollectionViewCell

在我的 CollectionView 中,单元格具有 class MyCollectionViewCell:

class MyCollectionViewCell: UICollectionViewCell {

@IBOutlet weak var myLabel: UILabel!
@IBOutlet weak var MyImageView: UIImageView!

}

我想将标签的文本设置为空,并在点击的单元格的 imageView 中显示图像。 collectionViewController 具有以下 class 和附加代码:

class CollectionViewController: UICollectionViewController {

var array:[String] = []

override func viewDidLoad() {
    super.viewDidLoad()

    array = ["1", "2", "3"]
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return array.count
}

override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    let cell:MyCollectionViewCell = collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as! MyCollectionViewCell

    var Label = cell.viewWithTag(1) as! UILabel

    Label.text = array[indexPath.row]

    return cell
}

override func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {

    println("user tapped on cell number \(indexPath.row)")

    //change ImageView of tapped cell   

}

}

如何编辑我在代码中放置评论的点击单元格?

在您的评论处,您可以使用:

let cell = collectionView.cellForItemAtIndexPath(indexPath) as! MyCollectionViewCell
cell.myLabel.hidden = true
cell.MyImageView.image = UIImage(named:"...")

您需要填写图片名称或根据图片来源选择不同的方法。
