AFNetworking - do not cache response


I'm using this code to pull a simple JSON feed from a server:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];

[manager GET:kDataUrl parameters:nil
 success:^(AFHTTPRequestOperation *operation, id responseObject) {
     NSLog(@"response: %@", responseObject);
 }
 failure:^(AFHTTPRequestOperation *operation, NSError *error) {
     NSLog(@"JSON DataError: %@", error);
 }];

It works. However, after I change the JSON file at kDataUrl, and verify that the change is made in a browser, when I run the app again, I still get the previous response.

It seems that AFNetworking is somehow caching the old response. I do not want this behavior. I want to download the current feed. Is there some kind of setting or parameter I need to set to turn off caching?


Solution

  • Make long story short, just define your AFNetworking manager:

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager.requestSerializer setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
    

    Enjoy!
