添加搜索栏以过滤uicollection视图

Question

我关注this tutorial。程序执行停止

 override func viewDidLoad() {
        super.viewDidLoad()

        collectionView.delegate=self /////error line 
        collectionView.dataSource=self /////error line

        self.searchController.searchResultsUpdater = self
        self.searchController.delegate = self
        self.searchController.searchBar.delegate = self

        self.searchController.hidesNavigationBarDuringPresentation = false
        self.searchController.dimsBackgroundDuringPresentation = true
        self.searchController.obscuresBackgroundDuringPresentation = false
        searchController.searchBar.placeholder = "Search for tools and resources"
        searchController.searchBar.sizeToFit()

        searchController.searchBar.becomeFirstResponder()

        self.navigationItem.titleView = searchController.searchBar



        // Do any additional setup after loading the view, typically from a nib.
    }

程序执行在这两行停止

 collectionView.delegate=self /////error line 
collectionView.dataSource=self /////error line

错误是

您的collectionView电子插座尚未与故事板中的UICollectionView相关联，请将它们连接起来，然后它就能正常工作。
