Question

我有SDWebImage的问题，我有一个UICollectionView，我正在尝试将网址图片转到indexPath。我被困了似乎我错过了单元格中的一个关键点。对此有任何帮助。我想这是愚蠢的事情，但是嘿..还要提到我有很多网址图片不仅仅是一个

这是我的结构

struct Regions {
let imageName: String
let imageUrl: String
let titleName: String
let action: String
let actionUrl: String

init(imageName: String, imageUrl: String, titleName: String, action: String, actionUrl: String) {

    self.imageName = imageName
    self.imageUrl = imageUrl
    self.titleName = titleName
    self.action = action
    self.actionUrl = actionUrl
}

}

我的追加方法

    actions.append(Regions(imageName: "agorianicam", imageUrl: "http://agorianicam.forecastweather.gr/agorianicam.jpg",  titleName: "Αγόριανη", action: "agoriani", actionUrl: "http://5.196.92.163:8080/agoriani.html"))

cellForItemAtIndexPath:方法

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! RegionListingCollectionCell

   // cell.imgView.sd_setImageWithURL.image = UIImage.init(named: actions[indexPath.row].imageUrl)
    cell.imgView.image = UIImage.init(named: actions[indexPath.row].imageName)
    cell.titleLabel?.text = actions[indexPath.row].titleName

    return cell

}

Answer 1

使用cell.imgView.sd_setImage(with: yourUrl, placeholderImage: anyPlaceholderImage)而不是分配图像。或者查看SDWebImage Doc了解更多信息。

所以根据你的代码，下面的代码应该适合你：

cell.imgView.sd_setImage(with: URL(string: actions[indexPath.row].imageUrl), placeholderImage: anyPlaceholderImage)

SDWebImage，在indexPath.row中获取url图像
