Ich habe eine UICollectionView in einem View-Controller. Wenn der Benutzer auf eines der Bilder klickt, wird das Bild auf einer separaten Seite geöffnet. Ich möchte nicht jedes Mal in die Galerie zurückkehren, um Bilder zu wechseln, nach links oder rechts wischen, um das nächste oder vorherige Bild zu erhalten.UICollectionView Scrollen/Swipe zum nächsten Element swift
Ich habe Antworten gesehen, um "pagingEnabled = true" zu tun, aber wo genau setzen Sie das?
Ich bin neu zu schnell.
Unten ist mein Code. Danke für die Hilfe im Voraus.
ViewController.swift
import UIKit
class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate
{
@IBOutlet weak var collectionView: UICollectionView!
let appleProducts = ["iPhone", "Apple Watch", "Mac", "iPad"]
let imageArray = [UIImage(named: "pug"), UIImage(named: "pug2"), UIImage(named: "pug3"), UIImage(named: "pug4")]
override func viewDidLoad()
{
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
{
return self.appleProducts.count
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell
{
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as! CollectionViewCell
cell.imageView?.image = self.imageArray[indexPath.row]
cell.titleLabel?.text = self.appleProducts[indexPath.row]
return cell
}
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath)
{
self.performSegueWithIdentifier("showImage", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?)
{
if segue.identifier == "showImage"
{
let indexPaths = self.collectionView!.indexPathsForSelectedItems()!
let indexPath = indexPaths[0] as NSIndexPath
let vc = segue.destinationViewController as! NewViewController
vc.image = self.imageArray[indexPath.row]!
vc.title = self.appleProducts[indexPath.row]
}
}
}
