【问题描述】：

我有如下的名字数组

["Acting Chief Justice Gita Mittal", "Justice S. Ravindra Bhat", "Justice Sanjiv Khanna", "Justice G. S. Sistani", "Justice Dr. S. Muralidhar", "Justice Hima Kohli", "Justice Vipin Sanghi", "Justice Siddharth Mridul", "Justice Manmohan"]

和下面的 URL 数组

["writereaddata%5Cupload%5CJudges/JImage_7ZV0X5SB.JPG", "writereaddata%5Cupload%5CJudges/JImage_31PR55RK.JPG", "writereaddata%5Cupload%5CJudges/JImage_TALSLWYH.JPG", "writereaddata%5Cupload%5CJudges/JImage_DDW7F8I4.JPG", "writereaddata%5Cupload%5CJudges/JImage_8MP3TXZ2.JPG", "writereaddata%5Cupload%5CJudges/JImage_3R72I03Q.JPG", "writereaddata%5Cupload%5CJudges/JImage_ZPL72GGF.JPG", "writereaddata%5Cupload%5CJudges/JImage_RHXYPY1N.JPG", "writereaddata%5Cupload%5CJudges/JImage_BR82DUAU.JPG"]  

我想在图像和标签上运行时在集合视图中快速显示这些。这该怎么做 ？

谢谢

【参考方案1】：

您可以通过SDWebImage 库在 TableView 和 CollectionView 中从URL 加载图像。

你喜欢 UITableView 和 UICollectionView 单元格中的这个。

cell.imageView.sd_setImage(with: URL(string: "yourImageURL"), placeholderImage: UIImage(named: "placeholder.png"))

【参考方案2】：

有一个很棒的 swift 库，用于下载和缓存图像，称为 SDWebImage。检查文档非常简单。
