@Claude31, here is my code for cellForItemAt:
`func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "post", for: indexPath) as! PostView
cell.setupView(post: posts[indexPath.row])
cell.vc = self
self.noPostsLabel.text = ""
return cell
}
`
Here is what cell.setupView() does:'
`
public func setupView(post: Post) {
print("Override has been called.")
contentView.addSubview(commentsButton)
contentView.addSubview(kuduAppTeamDeleteButton)
contentView.addSubview(titleLabel)
contentView.addSubview(infoButton)
contentView.addSubview(imageViewButton)
contentView.addSubview(likeButton)
contentView.addSubview(followButton)
contentView.addSubview(profile)
contentView.addSubview(likeCount)
contentView.addSubview(date)
contentView.addSubview(line)
addConstraints()
guard let post = fb.posts.firstIndex(where: { p in p.id == post.id }) else { return }
self.post = post
guard let user = fb.users.firstIndex(where: { user in user.id == fb.posts[post].uid }) else { return }
self.user = user
if fb.currentUser.likes.contains(fb.posts[post].id) {
self.likeButton.setImage(UIImage(systemName: "hand.thumbsup.fill"), for: .normal)
self.likeButton.tintColor = UIColor.theme.blueColor
} else {
self.likeButton.setImage(UIImage(systemName: "hand.thumbsup"), for: .normal)
self.likeButton.tintColor = .label
}
let result = String(format: "%ld %@", locale: Locale.current, fb.posts[post].likeCount, "")
likeCount.text = result
//Button Actions
infoButton.addAction(infoButtonAction, for: .touchUpInside)
likeButton.addAction(likeButtonAction, for: .touchUpInside)
followButton.addAction(followButtonAction, for: .touchUpInside)
imageViewButton.addAction(imageViewButtonAction, for: .touchUpInside)
profile.addAction(profileAction, for: .touchUpInside)
commentsButton.addAction(commentsButtonAction, for: .touchUpInside)
kuduAppTeamDeleteButton.addAction(kuduAppTeamDeleteButtonAction, for: .touchUpInside)
//Date
let dateFormatter = DateFormatter()
dateFormatter.timeStyle = .none
dateFormatter.dateStyle = .long
let dateString = dateFormatter.string(from: fb.posts[post].date)
date.text = dateString
//Set follow button text
if self.fb.currentUser.following.contains(fb.users[user].id) {
self.followButton.label.text = "Unfollow"
} else {
self.followButton.label.text = "Follow"
}
//Set imageview image
imageViewButton.setImage(fb.posts[post].image, for: .normal)
imageViewButton.imageView!.contentMode = .scaleAspectFill
//Set user image
profile.usernameLabel.text = fb.users[user].username
profile.profileImage.image = fb.users[user].profileImage
if profile.profileImage.image == UIImage(systemName: "person.circle.fill") {
profile.profileImage.tintColor = UIColor.theme.accentColor
}
//Set post title
titleLabel.text = fb.posts[post].title
}
`
Here is my prepareForReuse() func:
`
override func prepareForReuse() {
print("This is called.")
//Remove all actions
infoButton.removeAction(infoButtonAction, for: .touchUpInside)
likeButton.removeAction(likeButtonAction, for: .touchUpInside)
imageViewButton.removeAction(imageViewButtonAction, for: .touchUpInside)
profile.removeAction(profileAction, for: .touchUpInside)
commentsButton.removeAction(commentsButtonAction, for: .touchUpInside)
followButton.removeAction(followButtonAction, for: .touchUpInside)
kuduAppTeamDeleteButton.removeAction(kuduAppTeamDeleteButtonAction, for: .touchUpInside)
//Remove any other text or images
for subview in imageViewButton.subviews {
if let subview = subview as? UIImageView, subview.image == UIImage(systemName: "play.circle.fill") {
subview.removeFromSuperview()
}
}
imageViewButton.setImage(nil, for: .normal)
kuduAppTeamDeleteButton.color = nil
profile.profileImage.image = nil
titleLabel.text = nil
date.text = nil
self.followButton.label.text = nil
commentsButton.removeFromSuperview()
kuduAppTeamDeleteButton.removeFromSuperview()
titleLabel.removeFromSuperview()
infoButton.removeFromSuperview()
imageViewButton.removeFromSuperview()
likeButton.removeFromSuperview()
followButton.removeFromSuperview()
profile.removeFromSuperview()
likeCount.removeFromSuperview()
date.removeFromSuperview()
line.removeFromSuperview()
}
`
Hope that helps clarify things. Let me know if you need anything else. And thanks so much your last answer was super helpful!
