Swift - 如何在 UITableViewCell 中使用 CollectionViewCell 打开另一个视图控制器 [英] Swift - how to open another viewcontroller with CollectionViewCell inside UITableViewCell

问题描述

我真的是 iOS/Swift 的新手，而且我在做一个小项目.在这个项目中，我在 ViewController 中有一个 UITableView.我在 UITableViewCell 中有另一个文件自定义 CollectionViewCell.我希望当用户单击 collectionview 中的一个单元格时，它将打开另一个 ViewController 并从此 collectionviewcell 获取数据.这是我的 uitableview swift 文件:

I'm really new in iOS/Swift and i'm in a small project. In this project i have a UITableView inside ViewController. And i have another file custom CollectionViewCell in side UITableViewCell. I want when user click a cell in collectionview it will open another ViewController and it get data from this collectionviewcell. This is my uitableview swift file:

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)
}

我该怎么做?

推荐答案

你可以这样:

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，我不知道您要推送哪个视图或您的名称数组包含什么，因此请相应地更改这些内容.

This is just a way to do it i dont know which view you want to push or what your names array contains so kindly change those things accordingly.

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

get root navigationcontroller from uiapplication and perform push on it.
