@interface UIImage (MemoryCacheCost)

/**
|
|
The memory cache cost for specify image used by image cache. The cost function is the bytes size held in memory.
|
|
If you set some associated object to `UIImage`, you can set the custom value to indicate the memory cost.
|
|
|
|
For `UIImage`, this method return the single frame bytes size when `image.images` is nil for static image. Retuen full frame bytes size when `image.images` is not nil for animated image.
|
|
For `NSImage`, this method return the single frame bytes size because `NSImage` does not store all frames in memory.
|
|
@note Note that because of the limitations of category this property can get out of sync if you create another instance with CGImage or other methods.
|
|
@note For custom animated class conforms to `SDAnimatedImage`, you can override this getter method in your subclass to return a more proper value instead, which representing the current frame's total bytes.
