Question

我正在使用此代码将图像加载到我的UITableView中。

但是什么都没有加载，任何想法为什么？我在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，您不需要创建myImageView。

Answer 2

尝试将百分比转义添加到您的网址字符串。

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

UIImageView无法在UITableViewCell中运行
