I tried many days to realise this:
I want to add in my UIViewController two different CollectionView. For example I want to put images in these collectionView Each CollectionView use its own images. Is this possible?
I will be very happy if somebody can give me a hand. :)
This is possible, you just need to add each UICollectionView as a subview, and set the delegate and dataSource to your UIViewController.
Here's a quick example. Assuming you have one UICollectionView working, you should be able to adapt this code to your own uses to add a second fairly easily:
let collectionViewA = UICollectionView()
let collectionViewB = UICollectionView()
let collectionViewAIdentifier = "CollectionViewACell"
let collectionViewBIdentifier = "CollectionViewBCell"
override func viewDidLoad() {
// Initialize the collection views, set the desired frames
collectionViewA.delegate = self
collectionViewB.delegate = self
collectionViewA.dataSource = self
collectionViewB.dataSource = self
self.view.addSubview(collectionViewA)
self.view.addSubview(collectionViewB)
}
In the cellForItemAtIndexPath delegate function:
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
if collectionView == self.collectionViewA {
let cellA = collectionView.dequeueReusableCellWithReuseIdentifier(collectionViewAIdentifier) as UICollectionViewCell
// Set up cell
return cellA
}
else {
let cellB = collectionView.dequeueReusableCellWithReuseIdentifier(collectionViewBIdentifier) as UICollectionViewCell
// ...Set up cell
return cellB
}
}
In the numberOfItemsInSection function:
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
if collectionView == self.collectionViewA {
return 0 // Replace with count of your data for collectionViewA
}
return 0 // Replace with count of your data for collectionViewB
}
