Method retrying AFNetworking request n number of times. Not a perfect implementation, but this is just for saving the idea.

gistfile1.m

- (void)downloadFileRetryingNumberOfTimes:(NSUInteger)numberOfTimes 
                              success:(void (^)(id responseObject))success 
                              failure:(void (^)(NSError *error))failure
{
    if (numberOfTimes <= 0) {
        if (failure) {
            NSError *error = ...;
            failure(error);
        }
    } else {
        [self getPath:@"/path" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
            if (success) {
                success(...);
            }
        } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
            [self downloadFileRetryingNumberOfTimes:numberOfTimes - 1 success:success failure:failure];
        }];
    }
}
