how i send it array of images to use sdwebimage inside of collection view data to other vc Thank you for answers...
It is hard to understand what you want to do.
.
how i send it array of images
Where is this array defined ? What is its name ?
For example, if it is defined in PhoneListViewController as
var images: [UIImage]
What is the var that will receive the array in the destination controller (PDFViewController ?)
if it is defined as:
var receivedImages: [UIImage]?
Then, in prepare you have to write:
vc.receivedImages = self.images
Note: the forced unwrap at the end on cell! is dangerous.
You should better:
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "PhoneDetailsCC", for: indexPath) as? PhoneDetailsCC else { return UICollectionViewCell() }
let imageUrl = phoneModel?.imageUrl[indexPath.row]
cell.phoneDetailsImage.sd_setImage(with: URL(string: imageUrl!))
return cell
}
