如果图像网址没有变化但图像已更改,如Twitter或GitHub,如何使用翠鸟检索正确的图像。
SDWebImage有一个选项[SDWebImageRefreshCached]来解决问题。
/**
* Even if the image is cached, respect the HTTP response cache control, and refresh the image from remote location if needed.
* The disk caching will be handled by NSURLCache instead of SDWebImage leading to slight performance degradation.
* This option helps deal with images changing behind the same request URL, e.g. Facebook graph api profile pics.
* If a cached image is refreshed, the completion block is called once with the cached image and again with the final image.
*
* Use this flag only if you can't make your URLs static with embedded cache busting parameter.
