Question

我在swift中创建了集合视图语言我需要向这些单元格添加图像如何添加图像？

class ViewController: UIViewController,UICollectionViewDelegateFlowLayout,UICollectionViewDataSource {
    var collectionView: UICollectionView?

    override func viewDidLoad() {

        super.viewDidLoad()
        let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
        layout.sectionInset = UIEdgeInsets(top: 20, left: 10, bottom: 10, right: 10)
        layout.itemSize = CGSize(width: 90, height: 120)
        collectionView = UICollectionView(frame: self.view.frame, collectionViewLayout: layout)
        collectionView!.dataSource = self
        collectionView!.delegate = self
        collectionView!.registerClass(UICollectionViewCell.self, forCellWithReuseIdentifier: "Cell")
        collectionView!.backgroundColor = UIColor.blueColor()
        self.view.addSubview(collectionView!)

        // Do any additional setup after loading the view, typically from a nib.
    }

最简单的方法是在界面构建器中创建集合视图，子类uicollectionviewcell为uiimageview添加插座

class colCollectionViewCell: UICollectionViewCell {
    @IBOutlet var myImageView: UIImageView!
}

在该collectionview中添加一个动态单元格，将该单元格的类更改为您的子类。删除该单元格上的UIImageView，连接您的插座并从UICollectionView委托/数据源函数访问它。

override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as colCollectionViewCell
     cell.myImageView.image = UIImage(named:"myimagename")
    return cell
}

这是UICollectionView的一个很棒的教程：http://www.raywenderlich.com/78550/beginning-ios-collection-views-swift-part-1

你可以使用Haneke

样品

if let urlString = self.data?["images"]["standard_resolution"]["url"]{
            let url = NSURL(string: urlString.stringValue)
            self.imageView.hnk_setImageFromURL(url!)
        }
