ios - SDWebImage 展示方式求解？

Question

SDWebImage 有没有类似 YYWebImage 的 YYWebImageOptionSetImageWithFadeAnimation属性？
图片的展示方式是渐显的，而不是 duang 一下展示出来？
SDWebImageOptions枚举类型也没又发现类似的方式。

如果没有这种展现方式，应该如何修改源码？我在

- (void)sd_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options progress:(SDWebImageDownloaderProgressBlock)progressBlock completed:(SDWebImageCompletionBlock)completedBlock

添加动透明动画，并没什么效果。

求大神解释。

Answer 1

SDWebImage does not have this parsing method, please refer to yy blog for details
Just call the alpha animation when completed

Answer 2

Customize UIImageView category and call it inside sd_setImageWithURL... 并添加 SDWebImageAvoidAutoSetImage 的 options ，在完成时把 self.image = image; 放到 UIView animationWith... block.

Answer 3

It’s exactly the same as your question. Just take a look. It’s just that the effect of the animation is different. The specific location is also marked on the answer page
