我正在尝试将视图、单元格内、集合视图内的插座连接到我的视图控制器文件，但我不断收到此错误。

非法配置：HomeViewController 到 UIView 的 runningCard 接口无效。插座不能连接到重复的内容。

我应该怎么办？

你必须做这样的事情，希望这会有所帮助。

import UIKit

class CustomCollection: UICollectionViewCell {
@IBOutlet var myView: UIView!
/*
 Please note you have to create the outlet yourself and then
 drag it to a view that you add to your cell, you cant use your view from your cell.
 */
}
class ViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource {
@IBOutlet weak var collection: UICollectionView!
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return 5//Number of rows in cell
}
var viewFromCell = [UIView()]//This array of views gets assigned by the collectionview method bellow.
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collection.dequeueReusableCell(withReuseIdentifier: "myCell", for: indexPath) as! CustomCollection
    cell.myView = viewFromCell[indexPath.row]// This line of code gets the views from each cell and assigns them to the array of views declared above.
    return cell
}
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
 }
}

这就是你如何使用 UICollectionView 实现你的故事板
