Returning the Most Recent Cached Version THEN Downloading a New One

[m619]

I was wondering if AFCache can be used in the described way? It can help keep UIs way more responsive than simply waiting to retrieve the newest version of a file. If it can't be done with AFCache currently can you please describe which way would this be best implemented? Thank you. =]

There is a new option called kAFCacheReturnFileBeforeRevalidation causes AFCache to behave this way.

Example

[self.cache cacheItemForURL:absoluteURL urlCredential:nil completionBlock:^(AFCacheableItem *item) {
---
    } failBlock:^(AFCacheableItem *item) {
...
    } progressBlock:^(AFCacheableItem *item) {
...        
    } requestConfiguration: requestConfiguration];
