我想显示尽可能多的collectionViewCells与按钮,因为我的数组中有字符串.但是当我启动模拟器时,只有CollectionView的背景,没有显示单元格.什么可能是错误？
以下是我在CollectionViewController中附加到main.storyboard中的CollectionView的代码：
class CollectionViewController: UICollectionViewController {
var Array = [String]()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view,typically from a nib.
Array = ["1","2","3","4","5"]
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func collectionView(collectionView: UICollectionView,numberOfItemsSection section: Int) -> Int {
return Array.count
}
override func
collectionView(collectionView: UICollectionView,cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
var cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell",forIndexPath: indexPath) as! UICollectionViewCell
var button = cell.viewWithTag(1) as! UIButton
button.titleLabel?.text = Array[indexPath.row]
return cell
}
}
这些是Collection View Controller的连接：

解决方法
您是否将CollectionViewController设置为故事板身份检查器？
