<memory>不是BOMStorage文件

Question

当使用UICollectionView包含大量具有图像的单元格时,每当屏幕外单元格滚动到屏幕上时,我都会在日志中收到奇怪的警告:

2015-11-06 15:50:20.777 MyApp[49415:13109991] [/BuildRoot/Library/Caches/com.apple.xbs/Sources/CoreUI_Sim/CoreUI-370.8/Bom/Storage/BOMStorage.c:517] <memory> is not a BOMStorage file

这是单元设置:

import UIKit

class FeaturedCell: UICollectionViewCell {

    @IBOutlet weak var imageView: UIImageView!
    @IBOutlet weak var activityIndicator: UIActivityIndicatorView!

    private var xml: XMLIndexer? = nil

    override func awakeFromNib() {
        super.awakeFromNib()

        // this enables the parallax type look
        self.imageView.adjustsImageWhenAncestorFocused = true
        self.imageView.clipsToBounds = false
    }

    func loadImageFromUrlString(str: String) {
        if let url = NSURL(string: str) {
            if let data = NSData(contentsOfURL: url){
                let image = UIImage(data: data)
                self.imageView.image = image

                self.activityIndicator.stopAnimating();
            }
        }
    }

    func setXml(xml: XMLIndexer) {
        self.xml = xml;

        if let imageUrl: String = (xml["FullAd"].element?.text)! {
            self.loadImageFromUrlString(imageUrl)
        }
    }

}
