UIImageView在UITableViewCell中不起作用

Question

我正在使用此代码将图像加载到我的UITableView中。

但是什么都没有载入，有什么想法吗？ 当我NSLog时，链接是正确的。

NSString *temp = [appointmentDictionaryTemp objectForKey:@"patient_small_photo_url"]; 
NSData * imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:temp]];
UIImage * image = [UIImage imageWithData:imageData];
UIImageView * myImageView = [[UIImageView alloc] initWithImage:image];
cell.patientImage = myImageView; 

更新：

- (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;
}

Answer 1

您是否尝试过：

cell.patientImage.image = image;

当然，您无需创建myImageView 。

Answer 2

尝试将转义百分比添加到您的URL字符串中。

NSString *urlString = [[appointmentDictionaryTemp objectForKey:@"patient_small_photo_url"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
