ios - UICollectionView 数据未正确显示

Question

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let cell: MaterialCollectionViewCell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! MaterialCollectionViewCell
    let item = items()[indexPath.item]
    //print(cell.contentView.subviews)
    for view in cell.contentView.subviews{
        view.removeFromSuperview()
    }
    //print(cell.contentView.subviews)
    let colors = [UIColor.grayColor(), UIColor.darkGrayColor()]
    cell.backgroundColor = colors[indexPath.item % 2]

    let showTitle: UILabel = UILabel(frame: CGRect(x: 0, y: 0, width: cell.frame.width, height: cell.frame.height))
    showTitle.text = item.title
    showTitle.textAlignment = .Center
    showTitle.font = UIFont(name: "HelveticaNeue", size: 25.0)
    showTitle.textColor = MaterialColor.white
    showTitle.center = cell.center
    showTitle.hidden = true
    //print(showTitle.text)
    cell.contentView.addSubview(showTitle)


    let imageView: UIImageView = UIImageView(frame: CGRect(x: 0, y: 0, width: cell.frame.width, height: cell.frame.height))
    imageView.kf_setImageWithURL(NSURL(string: item.banner)!,
                                 placeholderImage: nil,
                                 optionsInfo: nil,
                                 progressBlock: { (receivedSize, totalSize) -> () in
                                    //print("Download Progress: \(receivedSize)/\(totalSize)")
        },
                                 completionHandler: { (image, error, cacheType, imageURL) -> () in
                                    //print("Downloaded and set!")
                                    if (image != nil) {
                                        showTitle.removeFromSuperview()
                                    }
                                    else {
                                        showTitle.hidden = false
                                    }
        }
    )
    cell.contentView.addSubview(imageView)
    //print(cell.contentView.subviews)
    return cell
}

这是我用来将数据显示到显示标题标签中的代码。目前 imageView 还没有显示 我的问题是没有显示完整的数据，而是显示了其中的一部分

current output

应该以相同的顺序显示这些

• 橙色是新的黑色
• 马可波罗 (2014)
• 感兴趣的人

我认为问题在于 UILabel View 和 UIImageView 重叠。您应该缩小 UILabel 的大小，并将 UIImageView 放在 UILabel 后面。
