我如何从 NSMutableArray 获取图像并发送到我的 collectionView

Question

我有这个数组：

override func viewDidLoad() {
        super.viewDidLoad()

        topDestinations = [["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"huehueuhe"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"huehueuhe"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel4.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"huehueuhe"],
            ["image": "hotel4.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel4.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel4.jpeg","name":"huehueuhe"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"vhuehueuhe"],
            ["image": "hotel4.jpeg","name":"Ibiza"],
            ["image": "hotel4.jpeg","name":"Ibiza"],
            ["image": "hotel4.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel2.jpeg","name":"Ibiza"],
            ["image": "hotel4.jpeg","name":"Ibiza"],
            ["image": "hotel4.jpeg","name":"Ibiza"]]
    }

我想获取相应的图片作为单元格，assemble这里：

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCellWithReuseIdentifier("TopDestinationsCell", forIndexPath: indexPath) as! UICollectionViewCell

        var hotelImageView : UIImageView = cell.viewWithTag(1) as! UIImageView
        var hotelNameLabel : UILabel = cell.viewWithTag(2) as! UILabel

        hotelImageView.image = topDestinations[indexPath.row]["image"] as? UIImage
        hotelNameLabel.text = topDestinations[indexPath.row]["name"] as? String

        return cell
    }

单元格名称右侧显示正确但 none 的照片出现

Answer 1

您应该使用数据中提供的图像名称制作一个新的 UIImage

UIImage(named: "imageName.jpg")

然后将其分配给 UIImageView

的图像属性

Answer 2

您必须实际加载 UIImageView 中的图像，而不仅仅是为其提供图像名称。这假定图像位于主包中（为此您可能不需要 .jpeg 扩展名）。

hotelImageView.image = UIImage(named: topDestinations[indexPath.row]["image"])
