SDWebImage混编

GitHub:https://github.com/SDWebImage/SDWebImage
cocoaPods

pod 'SDWebImage'

// 图片加载
let picPath = "https://dss3.bdstatic.com/70cFv8Sh_Q1YnxGkpoWK1HF6hhy/it/u=677762285,3327576538&fm=26&gp=0.jpg";
let picURL = NSURL(string: picPath);
SDWebImageManager.shared.loadImage(with: picURL as URL?, options: SDWebImageOptions.highPriority, progress: { (receivedSize:Int,expectedSize:Int,targetURL:URL?) in
    
}, completed:{ (image, data, error, SDImageCacheType, result, url) in
    view1.image = image;
    // 下载图片后不会将图片缓存到沙盒，需要手动调用SDImageCache.shared.store保存到沙盒
    SDImageCache.shared.store(image, forKey: url?.absoluteString, completion: {
        print("图片保存成功");
     })
})

AlamofireImage

GitHub:https://github.com/Alamofire/AlamofireImage
cocoaPods

pod 'AlamofireImage'

// 图片加载
let picPath = "https://dss3.bdstatic.com/70cFv8Sh_Q1YnxGkpoWK1HF6hhy/it/u=677762285,3327576538&fm=26&gp=0.jpg";
guard let picURL: URL = URL(string: picPath) else {
    view2.image = UIImage(named: "lty.jpg");
    return;
}

//view3.af.setImage(withURL: picURL);

let serializer = ImageResponseSerializer();
let placeholderImage = UIImage(named: "lty.jpg");
let filter = AspectScaledToFillSizeWithRoundedCornersFilter(
    size: CGSize(width: 100, height: 120),
    radius: 10.0
)

view3.af.setImage(withURL: picURL, cacheKey: nil,
                  placeholderImage: placeholderImage,
                  serializer: serializer,
                  filter: filter,
                  progress: { progress in
    
}, progressQueue: DispatchQueue.main, imageTransition: .crossDissolve(0.2), runImageTransitionIfCached: true) { response in
    
}

Kingfisher

GitHub:https://github.com/onevcat/Kingfisher
cocoaPods

pod 'Kingfisher'

// 图片加载
let picPath = "https://dss3.bdstatic.com/70cFv8Sh_Q1YnxGkpoWK1HF6hhy/it/u=677762285,3327576538&fm=26&gp=0.jpg";
guard let picURL: URL = URL(string: picPath) else {
    view2.image = UIImage(named: "lty.jpg");
    return;
}

//view2.kf.setImage(with: picURL);

let option:[KingfisherOptionsInfoItem] = [
    .scaleFactor(UIScreen.main.scale),
    .transition(.fade(1)),
    .cacheOriginalImage
];
view2.kf.setImage(with: picURL, placeholder: UIImage(named: "lty.jpg"), options: option, progressBlock: { (receivedSize, totalSize) in
    
}) { Result  in
    print(Result);
}
