当滚动浏览其中有一个CollectionView的TableView时崩溃

我有这个问题（ UICollectionView里面的UITableViewCell – AutoLayout ）

并尝试了几个解决scheme，这是在互联网上可用我带着这个@Pablo Romeu的答案我试着他的解决scheme，现在我有一个TableView与其中的collectionView单元格（它可以dynamic地改变其大小的内容），但是当滚动浏览我的表查看它碰到这个错误：

我无法弄清楚这个错误的原因，如果有人知道，请帮助我

将此代码添加到我的TableViewCell

  override func awakeFromNib() { super.awakeFromNib() // Initialization code // collectionViewContainer.frame = self.bounds; // collectionViewContainer.autoresizingMask = [.FlexibleWidth, .FlexibleHeight] let flow: UICollectionViewFlowLayout = (self.collectionView.collectionViewLayout as! UICollectionViewFlowLayout) // Configure the collectionView flow.minimumInteritemSpacing = 1 // This enables the magic of auto layout. // Setting estimatedItemSize different to CGSizeZero // on flow Layout enables auto layout for collectionView cells. // https://developer.apple.com/videos/play/wwdc2014-226/ flow.estimatedItemSize = CGSizeMake(1, 1) // Disable the scroll on your collection view // to avoid running into multiple scroll issues. self.collectionView.scrollEnabled = true } func bindWithModel(model: AnyObject) { // Do your stuff here to configure the tableViewCell // Tell the cell to redraw its contentView self.contentView.layoutIfNeeded() } // THIS IS THE MOST IMPORTANT METHOD // // This method tells the auto layout // You cannot calculate the collectionView content size in any other place, // because you run into race condition issues. // NOTE: Works for iOS 8 or later override func systemLayoutSizeFittingSize(targetSize: CGSize, withHorizontalFittingPriority horizontalFittingPriority: UILayoutPriority, verticalFittingPriority: UILayoutPriority) -> CGSize { // With autolayout enabled on collection view's cells we need to force a collection view relayout with the shown size (width) //self.collectionView.frame = CGRectMake(0, 0, targetSize.width, targetSize.height) self.collectionView.layoutIfNeeded() // If the cell's size has to be exactly the content // Size of the collection View, just return the // collectionViewLayout's collectionViewContentSize. return self.collectionView.collectionViewLayout.collectionViewContentSize() } 

这在我的CollectionViewCell中：

  class CollectionViewCell: UICollectionViewCell { @IBOutlet var imgView: UIImageView! override func awakeFromNib() { self.contentView.setNeedsLayout() } } 

这也在我的TableViewController：

  // Enable automatic row auto layout calculations self.tableView.rowHeight = UITableViewAutomaticDimension; // Set the estimatedRowHeight to a non-0 value to enable auto layout. self.tableView.estimatedRowHeight = 100

你的问题留在这条线

 return self.collectionView.collectionViewLayout.collectionViewContentSize() 

我已经取代了

 return CGSizeMake(self.collectionView.collectionViewLayout.collectionViewContentSize().width, 300); 

不要崩溃，但我相信，这不是你想要的，所以也许你可以看到这个提示更好的问题
