Issue Description and Steps

My imageView of a tableViewCell is flickering all the time I reload the tableview.
It only occurs using SDWebImage

on my tableViewCellForRow:

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

        AddUser_TableViewCell *cell;
        if (!cell) {
            cell = [tableView dequeueReusableCellWithIdentifier:@"UserAddCell" forIndexPath:indexPath];
        }
        User *user = searchModel.listOfUsers[indexPath.row];
        cell.delegate = self;
        cell.labelUsername.text    = user.username;
        cell.buttonAdd.selected    = user.following;
        cell.indexPath = indexPath;
        if(user.name){
            cell.name.hidden = NO;
            cell.name.text = user.name;
        }else{
            cell.name.hidden = YES;
        }

        [cell updateButtonUI];

        if(user.profilePictureURL){
            [cell.imageViewUser sd_setImageWithURL:user.profilePictureURL
                                  placeholderImage:nil
                                           options:SDWebImageProgressiveDownload];
        }else{
            cell.imageViewUser.image  = [UIImage imageNamed:@"avatar"];
        }

        return cell;

}

and the method to request the data from serve:

#pragma mark Search For Users
-(void)searchForUsers{
    if (searchModel.nextPageUsers == 0) {
        [self stopAnimationUsers];
        return;
    }
    if (self.searchBar.text.length <= 1 ) {
        timeHiRequestState = TimeHiRequestStateInactive;
        [searchModel.listOfUsers removeAllObjects];
        searchModel.listOfUsers = [NSMutableArray new];
        [self stopAnimationUsers];
        [self.tableViewUsers reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationNone];
        NSLog(@"*** reload data ***");
        return;
    }

    timeHiRequestState = TimeHiRequestStateLoading;
    [self.tableViewUsers reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationNone];

    [searchModel requestSearchPeopleWithName:self.searchBar.text success:^(AFHTTPRequestOperation *operation, id response, bool success){

        timeHiRequestState = TimeHiRequestStateSuccess;
        [self stopAnimationUsers];
        [self.tableViewUsers reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationNone];


    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        timeHiRequestState = TimeHiRequestStateError;
        [self stopAnimationUsers];
        [self.tableViewUsers reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationNone];
    }];
}

I have tried with both [reloadData] and [reloadSections withRowAnimation] and both are blinking the imageView

same here

[CavalcanteLeo]

it occurs on setShouldCacheImagesInMemory, just commented this line and it worked

[[SDImageCache sharedImageCache] setShouldCacheImagesInMemory:NO];

But if i don't use setShouldCacheImagesInMemory, SDWebImage will be really expensive, see #1544

+1 (Retraction: I thought this was the issue, but was something else. 4.0 is working in this regard for me)
