In my case, I am trying to create a UICollcetionView
with first cell add button for add user and from second cell I need to load Image array string into another cells. Here, I am using two separate cell
but I am not getting first cell into my output. Please provide me solution or another best method.
I am trying to get below output
Multiple Cell Code
// MARK: CollectionView Delegate
func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
return 2
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return imageArray.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
if indexPath.section == 0 {
let firstCell = collectionView.dequeueReusableCell(withReuseIdentifier: "addusercell", for: indexPath) as! AddParticipantsCollectionViewCell
return firstCell
} else {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "userscollectionview", for: indexPath as IndexPath) as! ParticipantsCollectionViewCell
cell.imageView?.image = self.imageArray[indexPath.row]
return cell
}
}
You need
if indexPath.item == 0 {
// first cell
}
else {
// second cell
cell.imageView?.image = self.imageArray[indexPath.item - 1]
}
Correct dataSource method ( remove it )
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1 // Section should set return 1 or default is optional
}
And change numberOfItemsInSection
to
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return imageArray.count + 1
}
If you have two sections in the collectionView you also need to set the number of items in each individual section:
// MARK: CollectionView Delegate
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 2
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
if section == 0 {
return 1 // return 1 item in cell (+ cell)
} else {
return imageArray.count
}
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
if indexPath.section == 0 {
let firstCell = collectionView.dequeueReusableCell(withReuseIdentifier: "addusercell", for: indexPath) as! AddParticipantsCollectionViewCell
return firstCell
} else {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "userscollectionview", for: indexPath as IndexPath) as! ParticipantsCollectionViewCell
cell.imageView?.image = self.imageArray[indexPath.row]
return cell
}
}
I hope it's been of any help.
