tengo unUITableView y unUITableCell subclase Cada celda de la mesa tiene dosscrollviews que cada una gire una cantidad dinámica de etiquetas, que se crean en la implementación de mi celda de tabla. Tengo un rendimiento de desplazamiento deficiente y creo que es por pérdidas de memoria. Estoy haciendo referencia a estostackoverflow correct answer to fix my problem: Gestión de memoria cellForRowAtIndexPath.

No puedo averiguar cómo modificar mi código para no tener que asignar memoria cada vez que creo etiquetas.

ViewController.m

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Custom Cell";

cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}


NSDictionary *dictionary = [parseDataArray objectAtIndex: indexPath.row];

NSArray *popularLinkTitleArray = [dictionary objectForKey:@"popularLinkTitleArray"];
NSString *soundCloudLink = [dictionary objectForKey:@"soundCloudLink"];
NSArray *soundCloudTrackTitleArray = [dictionary objectForKey:@"soundCloudTrackTitleArray"];


cell.artistNameLabel.text = artistName;

[cell createPopularLinkLabels: popularLinkTitleArray];

return cell;
}

CustomCell.m

- (void)layoutScrollLabelsForPopularLinkScrollView: (float)arrayCount
{
UIView *view = nil;
NSArray *subviews = [popularLinkScrollView subviews];

// reposition all image subviews in a horizontal serial fashion
CGFloat curXLoc = 0;
for (view in subviews)
{
    if ([view isKindOfClass:[UILabel class]] && view.tag >= 0)
    {
        CGRect frame = view.frame;
        frame.origin = CGPointMake(curXLoc, 0);
        view.frame = frame;

        curXLoc += (kScrollObjWidth);
    }
}

[popularLinkScrollView setContentSize:CGSizeMake((arrayCount * kScrollObjWidth),    [popularLinkScrollView bounds].size.height)];

}

-(void) createPopularLinkLabels:(NSArray *) popularLinkTitleArray
{

popularLinkScrollView.clipsToBounds = YES;

kScrollObjHeight = popularLinkScrollView.frame.size.height;
kScrollObjWidth = popularLinkScrollView.frame.size.width;

for (UIView* subView in popularLinkScrollView.subviews)
    [subView removeFromSuperview];

NSUInteger i;
    for (i = 0; i < popularLinkTitleArray.count; i++)
    {
        NSString *string = [NSString stringWithFormat:@"%@", [popularLinkTitleArray objectAtIndex: i]];
        UILabel *label = [[UILabel alloc] init];
        label.text = [NSString stringWithFormat:@"%@", string];
        label.backgroundColor = [UIColor clearColor];
        label.numberOfLines = 5;
        [label setFont:[UIFont fontWithName:@"Calibri" size:18]];

        // setup each frame to a default height and width, it will be properly placed when we call "updateScrollList"
        CGRect rect = label.frame;
        rect.size.height = kScrollObjHeight;
        rect.size.width = kScrollObjWidth;
        label.frame = rect;
        label.tag = i;  // tag our images for later use when we place them in serial fashion
        [popularLinkScrollView addSubview:label];
    }

[self layoutScrollLabelsForPopularLinkScrollView:popularLinkTitleArray.count];

}
