Swift – 如何在UITableViewCell中使用CollectionViewCell打开另一个viewcontroller

我是iOS / Swift的新手，我是一个小项目。 在这个项目中，我在ViewController中有一个UITableView。 我在UITableViewCell方面有另一个文件自定义CollectionViewCell。 我想当用户点击collectionview中的一个单元格时，它将打开另一个ViewController并从该collectionviewcell获取数据。 这是我的uitableview swift文件：

class IndexRow: UITableViewCell, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout { var names:[String] = ["Movie 1","Movie 2","Movie 3","Movie 4","Movie 5","Movie 6"] @IBOutlet weak var collectionView: UICollectionView! override func awakeFromNib() { super.awakeFromNib() collectionView.registerClass(indexOneMovie.self, forCellWithReuseIdentifier: "onemovie") let nib = UINib(nibName: "indexOneMovie",bundle: nil) collectionView.registerNib(nib, forCellWithReuseIdentifier: "onemovie") self.collectionView.backgroundColor = UIColor.clearColor() self.collectionView.delegate = self self.collectionView.dataSource = self print("Hello") } func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { return names.count } func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell { let cell = self.collectionView.dequeueReusableCellWithReuseIdentifier("onemovie", forIndexPath: indexPath) as! indexOneMovie cell.poster.image = UIImage(named: "poster.jpg") cell.name.text = names[indexPath.row] return cell } func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) { print(indexPath.item) } func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize { let itemsPerRow:CGFloat = 2 let hardCodedPadding:CGFloat = 0 let itemWidth = (collectionView.bounds.width / itemsPerRow) - hardCodedPadding let itemHeight = collectionView.bounds.height - (hardCodedPadding) return CGSize(width: itemWidth, height: itemHeight) } 

我怎么能这样做？

好吧，我最近在我的应用程序中实现了相同的这些是我最初提到的链接 –

http://www.thorntech.com/2015/08/want-your-swift-app-to-scroll-in-two-directions-like-netflix-heres-how/

你正在让uicollectionview委托确认uitableview单元格，这样你就无法呈现或推送到其他视图控制器。

这是我的代码希望它能帮到你

homeController.swift包含uitableview

  extension HomeController : UITableViewDelegate { func tableView(tableView: UITableView,willDisplayCell cell: UITableViewCell,forRowAtIndexPath indexPath: NSIndexPath) { guard let tableViewCell = cell as? TableViewCell else { return } //here setting the uitableview cell contains collectionview delgate conform to viewcontroller tableViewCell.setCollectionViewDataSourceDelegate(self, forRow: indexPath.row, andForSection: indexPath.section) tableViewCell.collectionViewOffset = storedOffsets[indexPath.row] ?? 0 } func tableView(tableView: UITableView,didEndDisplayingCell cell: UITableViewCell,forRowAtIndexPath indexPath: NSIndexPath) { guard let tableViewCell = cell as? TableViewCell else { return } storedOffsets[indexPath.row] = tableViewCell.collectionViewOffset } } extension HomeController: UICollectionViewDelegate, UICollectionViewDataSource { func collectionView(collectionView: UICollectionView,numberOfItemsInSection section: Int) -> Int { let element : [CollectionViewElement] = self.returnCollectionViewElementAccordingToIndex(collectionView.tag) return element.count } func collectionView(collectionView: UICollectionView,cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell { let cell = collectionView.dequeueReusableCellWithReuseIdentifier("Cell",forIndexPath: indexPath) as! horizontalCollectionViewCell let element : [CollectionViewElement] = self.returnCollectionViewElementAccordingToIndex(collectionView.tag) cell.cellTitleLabel.text = element[indexPath.row].videos.title cell.cellGenerLabel.text = element[indexPath.row].videos.gener return cell } func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath){ print("collectionviewtag:\(collectionView.tag) + indexpathrow:\(indexPath.row)") //from here you can do push or present to anyview controller // collectionviewtag is tableView cell row value and indexpathrow return collectionView cell row value. } } 

TableViewCell.swift：包含collectionView的自定义UITableViewCell

  class TableViewCell: UITableViewCell { @IBOutlet private weak var collectionView: UICollectionView! @IBOutlet weak var cellLabel: UILabel! @IBOutlet weak var cellButton: UIButton! @IBAction func CellButtonActionTry(sender: UIButton) { print("Dude \(cellButton.tag)") } var collectionViewOffset: CGFloat { get { return collectionView.contentOffset.x } set { collectionView.contentOffset.x = newValue } } func setCollectionViewDataSourceDelegate> (dataSourceDelegate: D, forRow row: Int , andForSection section : Int) { collectionView.delegate = dataSourceDelegate collectionView.dataSource = dataSourceDelegate collectionView.tag = row // tableView indexpathrow equals cell tag collectionView.reloadData() } override func awakeFromNib() { super.awakeFromNib() // Initialization code } override func setSelected(selected: Bool, animated: Bool) { super.setSelected(selected, animated: animated) } } 

Answer 2

你可以这样做：

 func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) { print(indexPath.item) let name = names[indexPath.item] let distinationViewController = DistinationViewController() distinationViewController.name = name if let navVC: UINavigationController = UIApplication.sharedApplication().keyWindow?.rootViewController as? UINavigationController { navVC.pushViewController(distinationViewController, animated: true) } } 

这只是一种方法，我不知道你想要推送哪个视图或你的名字数组包含什么，所以请相应地改变这些东西。

从uiapplication获取root navigationcontroller并对其执行推送。
