使用SDWebImage將圖像下載到NSHomeDirectory

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;
                  }];

該代碼可以設置頭像的圖像，並且我想同時將服務器圖像（從imageUrl）下載到NSHomeDirectory ，該怎么辦？

在EGOCache中查找本地存儲圖像。 https://github.com/enormego/EGOCache您可以使用默認的EGOCache目錄（位於NSCachesDirectory內部）或使用您自己的目錄對其進行初始化。

用法很簡單：

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