使用Swift的UICollectionView

Question

在我的项目中，我在UICollectionViewCell中创建了Cell

由于未捕获的异常，其出现了“错误终止”应用程序

代码如下。

GalleryCell.swift

class GalleryCell: UICollectionViewCell
{


@IBOutlet var titleLabel : UILabel


init(coder aDecoder: NSCoder!)
{
    super.init(coder: aDecoder)
}
}

我在My ViewController中使用了该单元格：

代码如下：

NextViewController.swift

import UIKit

 class NextViewController: UIViewController
 {

@IBOutlet var collectionView : UICollectionView



var ListArray=NSMutableArray()



override func viewDidLoad()
{
    super.viewDidLoad()


    for i in 0..70
    {
         ListArray .addObject("C: \(i)")
    }




}



   func collectionView(collectionView: UICollectionView, numberOfItemsInSection section:Int)->Int
    {
        return ListArray.count
   }


func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath:NSIndexPath)->UICollectionViewCell
{

  var  cell = collectionView.dequeueReusableCellWithReuseIdentifier("CELL", forIndexPath: indexPath) as GalleryCell


    cell.titleLabel.text="\(ListArray.objectAtIndex(indexPath.item))"

    return cell
}


func collectionView(collectionView : UICollectionView,layout collectionViewLayout:UICollectionViewLayout,sizeForItemAtIndexPath indexPath:NSIndexPath) -> CGSize
{

    return CGSizeMake(66, 58)
}



override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}

我的问题是我遇到以下错误：

***** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'could not dequeue a view of kind: UICollectionElementKindCell with identifier CELL - must register a nib or a class for the identifier or connect a prototype cell in a storyboard'*** First throw call stack:**

Answer 1

我加入以下两行NextViewController.swift下viewDidLoad()：

var nibName = UINib(nibName: "GalleryCell", bundle:nil)

collectionView.registerNib(nibName, forCellWithReuseIdentifier: "CELL")

问题是我没有注册笔尖。现在我正在这样做，它工作正常。
