UICollectionViewcell calling functions over and over

Question

I have go this uicollectionviewcell

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
{
             


        

Answer 1

This happens because cells are being reused. The easiest way to handle this is to store index paths of cells with text in your view controller. When cell is dequeued just check if index path is present in stored array and layout accordingly.

In your ViewController

var cellsWithText: [IndexPath] = []

In cellForItemAt indexPath

...
cell.postImage.image = nil
cell.cellConstraintsWithoutImageWithText()
if !cellsWithText.contains(indexPath) {
    cellsWithText.append(indexPath)
}
...

Now at the beginning at cellForItemAt indexPath

if let CurrentPost = posts[indexPath.row] as? Post {
    if cellsWithText.contains(indexPath) {
    // layout for text
    } else {
    // layout for image
    }

I also noticed that your'e using posts[indexPath.row] but your using the collectionView, that doesn't have rows and has item instead. That also might be the issue.
