使用SDWebImage将图像下载到NSHomeDirectory中

Question

__block UIActivityIndicatorView *activityIndicator;
__weak UIImageView *weakImageView = self.headpic;
[self.headpic setImageWithURL:imageUrl placeholderImage:nil options:SDWebImageProgressiveDownload progress:^(NSInteger receivedSize, NSInteger expectedSize){
if (!activityIndicator) {
    [weakImageView addSubview:activityIndicator = [UIActivityIndicatorView.alloc initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]];
    activityIndicator.center = weakImageView.center;
    [activityIndicator startAnimating];
  }
}
                  completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType){
                      [activityIndicator removeFromSuperview];
                      activityIndicator = nil;
                  }];

此代码可以设置headpic的图像，我想同时下载服务器图像（从imageUrl）到NSHomeDirectory，该怎么办？

在本地查看EGOCache的商店图片。 https://github.com/enormego/EGOCache 您可以使用默认的EGOCache目录（在NSCachesDirectory中）或使用您自己的目录初始化它。

用法非常简单：

[[EGOCache globalCache] setImage:image forKey:@"your_key"];
