如何使图像在UITableViewCell滚动平滑？ [英] How to make Images in UITableViewCell scroll smoothly?

问题描述

我正在加载图像到我的UITableViewCell，它变得浪潮。我只有大约5-10个单元格。

I'm loading images into my UITableViewCell and it is becoming choppy. I only have around 5-10 cells max.

有没有简单的方法来解决这个问题？

Are there any easy ways to fix this?

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

    AppointmentTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    NSDictionary *appointmentDictionaryTemp = [self.appointmentArray objectAtIndex:indexPath.row];
    cell.patientNameLabel.text = [appointmentDictionaryTemp objectForKey:@"patient"];
    cell.appointmentTimeLabel.text = [appointmentDictionaryTemp objectForKey:@"scheduled_time"];

    NSString *urlString = [[appointmentDictionaryTemp objectForKey:@"patient_small_photo_url"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSData * imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlString]];
    UIImage * image = [UIImage imageWithData:imageData];
    cell.patientImage.image = image; 

    return cell;
}
