click on button in uicollection cell to segue - swift

Question

A have a button within a collectionviewcell and when I click on the button, the goal is to segue to a more detailed view controller.
class WelcomeViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate,UIGestureRecognizerDelegate, UISearchBarDelegate {
#IBOutlet weak var CollectionView: UICollectionView!
var databaseRef = FIRDatabase.database().reference()
var loggedInUser = FIRAuth.auth()?.currentUser
var dictDetails: [String:AnyObject]?
var posts = NSMutableArray()
let storage = FIRStorage.storage()
override func viewDidLoad() {
super.viewDidLoad()
(CollectionView.collectionViewLayout as! UICollectionViewFlowLayout).itemSize = CGSize(width: (self.view.frame.width - 10) / 2.4, height: (self.view.frame.width - 10) / 1.5 )
self.navigationItem.title = "Lit Swap"
CollectionView.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 300)
self.CollectionView.contentInset = UIEdgeInsetsMake(-65, 0, 0, 0)
definesPresentationContext = true
loadData()
}
#IBAction func editButtonTapped() -> Void {
print("Hello Edit Button")
performSegue(withIdentifier: "UsersProfile", sender: self)
func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "UsersProfile" {
self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
if let indexPaths = self.CollectionView!.indexPathsForSelectedItems{
///I DONT THINK YOU SHOULD REFERENCE POST, REFERENCE BOOKS INSTEAD///////////////
// if let indexPaths = self.CollectionView.cellForItem(at: <#T##IndexPath#>){
let vc = segue.destination as! UsersProfileViewController
let cell = sender as! UICollectionViewCell
let indexPath = self.CollectionView!.indexPath(for: cell)
let post = self.posts[(indexPath?.row)!] as! [String: AnyObject]
// let username = post["username"] as? String
let userpicuid = post["uid"] as? String
// vc.username = username
vc.userpicuid = userpicuid
print(indexPath?.row)
}} }
}
func loadData(){
if (FIRAuth.auth()?.currentUser) != nil{
FIRDatabase.database().reference().child("books").observeSingleEvent(of: .value, with: { (snapshot:FIRDataSnapshot) in
let loggedInUserData = snapshot
if let postsDictionary = snapshot .value as? [String: AnyObject] {
for post in postsDictionary {
self.posts.add(post.value)
}
self.CollectionView.reloadData()
}})}
}
// Properties of the UICollectionView
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int{
return self.posts.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! PinterestLikeCollectionViewCell
//configure the cell...
if (FIRAuth.auth()?.currentUser) != nil{
print(posts[indexPath.row])
let post = self.posts[indexPath.row] as! [String: AnyObject]
cell.Title.text = post["title"] as? String
cell.Author.text = post["Author"] as? String
let editButton = UIButton(frame: CGRect(x: 8, y: 225, width: 154, height: 45))
editButton.addTarget(self, action: #selector(editButtonTapped), for: UIControlEvents.touchUpInside)
editButton.tag = indexPath.row
print(indexPath.row)
editButton.isUserInteractionEnabled = true
cell.addSubview(editButton)
if let imageName = post["image"] as? String {
let imageRef = FIRStorage.storage().reference().child("images/\(imageName)")
imageRef.data(withMaxSize: 25 * 1024 * 1024, completion: { (data, error) -> Void in
if error == nil {
let image = UIImage(data: data!)
cell.Books.image = image
cell.Books.roundCornersForAspectFit(radius: 10)
cell.Books.clipsToBounds = true
}else {
print("Error downloading image:" )
}})}}
return cell
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: CGFloat((collectionView.frame.size.width / 5) - 20), height: CGFloat(500))
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "details" {
self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]

let post = self.posts[(indexPath?.row)!] as! [String: AnyObject]
let Booked = post["title"] as? String
let Authors = post["Author"] as? String
let ISBNS = post["ISBN"] as? String
let Prices = post["Price"] as? String
let imageNames = post["image"] as? String
let imagesTwo = post["imageTwo"] as? String

let imagesFive = post["imageFive"] as? String
vc.Booked = Booked
vc.Authors = Authors
vc.ISBNS = ISBNS
vc.Prices = Prices

vc.imagesTwo = imagesTwo

}
However, it does not do anything. I currently have my cell setup that when you click on it, it segues to a detailed view controller. But the button within the cell, when clicked should go to a different detailed view controller. For the cell's segue, the information to segue what put in the didSelectItemAt function. I am not sure what function to include the segue for the button in the cell.

Answer 1

Can you include your class as whole so I can get a better understanding of how your configuring the views? I'll update my answer with what I think would help, from what there's I think there a few different things that could be happening to cause this.
UPDATE
Try this:
Create and add your button in your PinterestLikeCollectionViewCell class.
Make a protocol that will tell it's delegate to preform your your action when the cell button is clicked.
Assign your WelcomeViewController class as that delegate and conform to the protocol.
