直接code糖荒！
加載圖片時(shí)用的方法如下：
[self.imageView sd_setImageWithURL:[NSURL URLWithString:urlStr]];
加載不出來最新的圖片舶沿，改用下面的方法特愿，去解決問題：
[self.imageView sd_setImageWithURL:[NSURL URLWithString:urlStr] placeholderImage:nil options:SDWebImageRefreshCached];
除了上面的修改之外，我們還需要在SDWebImage的內(nèi)部光酣，SDWebImageManager.m文件中疏遏，大概180行左右吧，把之前的代碼：
if (image && options & SDWebImageRefreshCached) {
// force progressive off if image already cached but forced refreshing
downloaderOptions &= ~SDWebImageDownloaderProgressiveDownload;
// ignore image read from NSURLCache if image if cached but force refreshing
downloaderOptions |= SDWebImageDownloaderIgnoreCachedResponse;
}
更換成如下：
if (image && options & SDWebImageRefreshCached) {
// force progressive off if image already cached but forced refreshing
downloaderOptions &= ~SDWebImageDownloaderProgressiveDownload;
替換下面
// remove SDWebImageDownloaderUseNSURLCache flag
downloaderOptions &= ~SDWebImageDownloaderUseNSURLCache;
替換上面
// ignore image read from NSURLCache if image if cached but force refreshing
downloaderOptions |= SDWebImageDownloaderIgnoreCachedResponse;
}
好久沒有寫更新了救军，以后要堅(jiān)持安埔臁！
