关于wepP图片不能显示，并把SDWebImage版本升级到4.7.0

[fengshh93]

在YBIBDefaultWebImageMediator.m头部导入#import "UIImage+MultiFormat.h" 把方法yb_downloadImageWithURL修改一下

(id)yb_downloadImageWithURL:(NSURL *)URL requestModifier:(nullable YBIBWebImageRequestModifierBlock)requestModifier progress:(nonnull YBIBWebImageProgressBlock)progress success:(nonnull YBIBWebImageSuccessBlock)success failed:(nonnull YBIBWebImageFailedBlock)failed { if (!URL) return nil;

SDWebImageDownloadToken *token = [[SDWebImageDownloader sharedDownloader] downloadImageWithURL:URL options:SDWebImageDownloaderLowPriority progress:^(NSInteger receivedSize, NSInteger expectedSize, NSURL * _Nullable targetURL) { if (progress) progress(receivedSize, expectedSize); } completed:^(UIImage * _Nullable image, NSData * _Nullable data, NSError * _Nullable error, BOOL finished) {

if (error) { if (failed) failed(error, finished); } else { SDImageFormat imgFType= [NSData sd_imageFormatForImageData:data]; if (imgFType == SDImageFormatUndefined || imgFType == SDImageFormatWebP) {//处理webP图片不能显示的情况 data = UIImageJPEGRepresentation(image, 1); } if (success) success(data, finished); } }]; return token;

}

主要是webp图片请求成功，但是YBIBImageData 的loadURL_download方法转换失败导致 所以在yb_downloadImageWithURL添加了webP图片的处理代码 SDImageFormat imgFType= [NSData sd_imageFormatForImageData:data]; if (imgFType == SDImageFormatUndefined || imgFType == SDImageFormatWebP) {//处理webP图片不能显示的情况 data = UIImageJPEGRepresentation(image, 1); }
