problem while unarchive cached object

[driventokill]

line 289 in EGOCache.m method - (UIImage*)imageForKey:(NSString*)key.
[NSKeyedUnarchiver unarchiveObjectWithFile:cachePathForKey(_directory, key)] return nil and throw a exception:
*** -[NSKeyedUnarchiver initForReadingWithData:]: incomprehensible archive (0xffffffff, 0xffffffd8, 0xffffffff, 0xffffffe0, 0x0, 0x10, 0x4a, 0x46)
Does anyone else have this problem? I got this problem while using EGOImageLoading.

i think NSKeyedUnarchiver cannot read content data of image file.

#if TARGET_OS_IPHONE

• (UIImage_)imageForKey:(NSString_)key {
  UIImage* image = nil;

  @Try {
  image=[[[UIImage alloc]initWithContentsOfFile:cachePathForKey(_directory, key)]autorelease];
  //image = [NSKeyedUnarchiver unarchiveObjectWithFile:cachePathForKey(_directory, key)];
  } @catch (NSException* e) {
  // Surpress any unarchiving exceptions and continue with nil
  }

  return image;
  }

You are correct - it may be better to change EGOImageLoader.m to archive the image via setImage:

• (void)imageLoadConnectionDidFinishLoading:(EGOImageLoadConnection *)connection {
  ...
  } else {
  // [[EGOCache currentCache] setData:connection.responseData forKey:keyForURL(connection.imageURL,nil) withTimeoutInterval:604800];

  [[EGOCache currentCache] setImage:anImage forKey:keyForURL(connection.imageURL,nil) withTimeoutInterval:604800];
