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?
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.
