UICollectionViewCell. I want to add 2 different picture cells - ios

Question

import UIKit
let reuseIdentifier = "MyCell"
class ViewController: UIViewController, UICollectionViewDataSource {
var myimage = UIImage(named: "1433584709_clock_ios7_ios_7")
#IBOutlet weak var collectionView: UICollectionView!
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! CollectionViewCell
cell.imageView.image = myimage
return cell
}
override func viewDidLoad() {
super.viewDidLoad()
self.collectionView.collectionViewLayout = CollectionViewLayout()
self.collectionView.registerClass(CollectionViewCell.self, forCellWithReuseIdentifier: "MyCell")
// Do any additional setup after loading the view, typically from a nib.
}
}
I have this code to add so many cells with same image.
However, I want to make cells to have different pictures.
Please tell me how to do this.

Answer 1

Use array of images instead of var myImage because collection view or tableview need some form of list or array to store all items. The indexPath.row will return the index of the images the collectionview is looking for. i.e.
var images: [String] = ["image1", "image2"]
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! CollectionViewCell
cell.imageView.image = UIImage(named: self.images[indexPath.row])
return cell
}
Also in function collectionView:numberOfItemsInSection:
return self.images.count
Here is the complete code assuming you have a custom CollectionViewCell class
class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {
#IBOutlet weak var collectionView: UICollectionView!
var images : [String] = ["image1", "image2"]
private let reuseIdentifier = "MyCell"
override func viewDidLoad() {
super.viewDidLoad()
self.collectionView.registerClass(CollectionViewCell.self, forCellWithReuseIdentifier: "MyCell")
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! CollectionViewCell
cell.imageView.image = UIImage(named: self.images[indexPath.row])
return cell
}
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return self.images.count
}
}

Answer 2

Where are your images coming from?
Suppose I have a 2D array of images like myImageArray[][], then change line:
cell.imageView.image = myImage
to
cell.imageView.image = myImageArray[indexPath.section][indexPath.row]
