将图像加载到UICollectionVIewCell中

Question

我有问题将图像设置为UiCollectionViewCell

这是我的代码：

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    NSURL * imageURL = [NSURL URLWithString:@"https://mozorg.cdn.mozilla.net/media/img/firefox/firstrun/logo.png?2013-06"];
    NSData * imageData = [NSData dataWithContentsOfURL:imageURL];
    UIImage * image = [UIImage imageWithData:imageData];
    UIImageView * myImageView = [[UIImageView alloc] initWithImage:image];

    myImageView.image = [UIImage imageNamed:@"myimg"];//set the image

    GLCell *cell = (GLCell *)[collectionView dequeueReusableCellWithReuseIdentifier:CELL_IDENTIFIER forIndexPath:indexPath];
    cell.displayString = [NSString stringWithFormat:@"%d user number", indexPath.row];
    cell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"myimg"]];


    return cell;
}

字符串值显示没有问题，但单元格没有图像。

   NSURL * imageURL = [NSURL URLWithString:@"https://mozorg.cdn.mozilla.net/media/img/firefox/firstrun/logo.png?2013-06"];
    NSData * imageData = [NSData dataWithContentsOfURL:imageURL];
    UIImage * image = [UIImage imageWithData:imageData];

    GLCell *cell = (GLCell *)[collectionView dequeueReusableCellWithReuseIdentifier:CELL_IDENTIFIER forIndexPath:indexPath];
    cell.displayString = [NSString stringWithFormat:@"%d user number", indexPath.row];
    cell.backgroundColor = [UIColor colorWithPatternImage:image]];

您没有将myImageView添加到您的单元格。您可以只使用UITableViewCell的imageView属性

，而不是创建自己的UIImageView。
