对SDWebImage进行修改，在"UIImage+MultiFormat.m"文件中

+ (nullable UIImage *)sd_imageWithData:(nullable NSData *)data {
    if (!data) {
        return nil;
    }
    
    UIImage *image;
    SDImageFormat imageFormat = [NSData sd_imageFormatForImageData:data];
    if (imageFormat == SDImageFormatGIF) {
        image = [UIImage sd_animatedGIFWithData:data];
    }
#ifdef SD_WEBP
    else if (imageFormat == SDImageFormatWebP)
    {
        image = [UIImage sd_imageWithWebPData:data];
    }
#endif
    else {
        image = [[UIImage alloc] initWithData:data];
        //添加下面一部分代码
        if (data.length/1024 > 128) {
            image = [self compressImageWith:image];     // 压缩过大的图片数据
        }
#if SD_UIKIT || SD_WATCH
        UIImageOrientation orientation = [self sd_imageOrientationFromImageData:data];
        if (orientation != UIImageOrientationUp) {
            image = [UIImage imageWithCGImage:image.CGImage
                                        scale:image.scale
