在Swift中使用另一个类的UICollectionView

Question

我正在尝试编写一个类来显示一个collectionView。 我试图将collectionView作为子视图添加到调用类的UIView时遇到了麻烦。 这可能吗？ 非常感谢任何见解。

ViewController：

import UIKit
class ViewController: UIViewController{
  override func viewDidLoad() {
    super.viewDidLoad()
    let editMenu = collection(view: view, xPos: 0, yPos: 0, width: view.frame.width, height: view.frame.height)
   }
}

和集合视图Class：

import UIKit
class collection: UIViewController, UICollectionViewDelegateFlowLayout, UICollectionViewDataSource {  
  var collectionView: UICollectionView?
  let cellIdentifier = "CellIdentifier"
  var myView = UIView()
  var xPos, yPos, width, height: CGFloat 
  required init(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
  }  
  init(view: UIView, xPos: CGFloat, yPos: CGFloat, width: CGFloat, height: CGFloat) {
    self.myView = view
    self.xPos = xPos
    self.yPos = yPos
    self.width = width
    self.height = height
    super.init(nibName: nil, bundle: nil)
    configureCollection()    
  }
  func configureCollection()
  {
    let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
    layout.sectionInset = UIEdgeInsets(top: 00, left: 10, bottom: 10, right: 10)
    layout.itemSize = CGSize(width: 100, height: 80)   
    let frame = CGRectMake(xPos, yPos, width, height)
    collectionView = UICollectionView(frame: frame, collectionViewLayout: layout)
    collectionView!.registerClass(UICollectionViewCell.self, forCellWithReuseIdentifier: cellIdentifier)
    collectionView!.backgroundColor = UIColor.redColor()
    collectionView!.dataSource = self
    collectionView!.delegate = self
    myView.addSubview(collectionView!)    //<- EXC_BAD_ACCESS    
  }
  func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return 4
  } 
  func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
    return 2
  }
  func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCellWithReuseIdentifier(cellIdentifier, forIndexPath: indexPath) as! UICollectionViewCell

    var textLabel = UILabel(frame: CGRectMake(0, 0, cell.frame.size.width, cell.frame.size.height))
    textLabel.textAlignment = NSTextAlignment.Center
    textLabel.textColor = UIColor.darkTextColor()
    textLabel.text = "Cell \(indexPath.row)"
    cell.contentView.addSubview(textLabel)

    return cell
  }
  func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
    NSLog("selected \(indexPath.row)")
  }
}
