set image to imageview in uicollectionview that is in uitableviewcell xib - swift

Question

I have taken a UITableView and deque a UITableViewCell XIB and set data to a label in it, also I have UICollectionView in UITableViewCell XIB in which I have to set images in a UICollectionViewCell.
UIImageView is in UICollectionViewCell and respective UICollectionView is in UITableViewCell so how to set an image to that UIImageView?
also have tableview delegate function in one file
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.discoverData.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "discoveryTableViewCell", for: indexPath) as! discoveryTableViewCell
let data = discoverData[indexPath.row]
cell.messageLbl.text = (data["content"] as! String)
// This how normally image is set in tableview, how to do with collectionview
cell.userImage.pin_updateWithProgress = true
let riderImage = URL(string: (data["profile_pic"] as! String))
cell.userImage.pin_setImage(from: riderImage, placeholderImage: nil, completion: nil)
return cell
}
collection view delegate function in UITableViewCell.
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return numCell
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "discoverCell", for: indexPath as IndexPath) as! discoverCollectionViewCell
cell.postImage.backgroundColor = .cyan
return cell
}
Here is a picture of how it looks yellow box is UICollectionView and cyan color box is UIImageView.

Answer 1

In cellForRowAt indexPath:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "discoveryTableViewCell", for: indexPath) as! discoveryTableViewCell
if let data = discoverData[indexPath.row] as? [String: Any] {
cell.messageLbl.text = (data["content"] as! String)
cell.data = data
}
return cell
}
In your "discoveryTableViewCell" (It should be "DiscoveryTableViewCell") :
var data: [String: Any] {
didSet {
collectionView.reloadData()
}
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "discoverCell", for: indexPath as IndexPath) as! discoverCollectionViewCell
if let profilePic = data["profile_pic"] as? String {
let riderImage = URL(string: profilePic)
cell.postImage.pin_setImage(from: riderImage, placeholderImage: nil, completion: nil)
}
return cell
}
You should follow the proper style guide and naming conventions in Swift.
