UITableViewCell Delete content - ios

Question

I am having trouble with the reusable aspect of my UITableViewCell. I have different type of data going into the different cells. When the types of data are the same (example: only images) I have no problem because the new image over writes the old one. But when the types of data are the same they both are sticking around.
I'm looking for methods or tools for clearing a cell completely. I have tried many things such as dictionaries to reference the data directly and erase it but that failed because I couldn't consistently tell what data was in what reused cell (especially when scrolling a lot). Others things were
cell.contentView.subviews.removeAll()
threw error, another was
cell.contentView.removeFromSuperView()
but that just made the cell useable and nothing loaded ever.
my code is below, thanks if advance for the help (ignore the date stuff).
if dictionary?["type"]! != nil {
cell.imageView?.layer.borderColor = UIColor.black.cgColor
cell.layer.borderWidth = 1
cell.imageView?.layer.cornerRadius = 1
cell.imageView?.frame = CGRect(x: 0, y: UIScreen.main.bounds.height/2, width: 25, height: 25)
self.tableTextOverLays(i: indexPath.row, type: Int((dictionary?["type"])! as! NSNumber), cell: cell)
if (indexPath.row == tableFeedCount - 1) && lockoutFeed != true && tableFeedCount == self.allDictionary.count && imageFeedCount == imageDictionary.count {
let dictionary = self.allDictionary[indexPath.row]
let date = dictionary?["date"] as! Double
let date2 = date*100000
let date3 = pow(10,16) - date2
let date4 = String(format: "%.0f", date3)
self.setUpFeed(starting: date4, queryLimit: UInt(11))
}
}
else if (dictionary?["type_"] as! String) == "Image" {
print("image feed", indexPath.row)
cell.imageView?.layer.borderColor = UIColor.black.cgColor
cell.layer.borderWidth = 1
cell.imageView?.layer.cornerRadius = 1
cell.imageView?.frame = CGRect(x: 0, y: UIScreen.main.bounds.height/2, width: 25, height: 25)
cell.imageView?.image = imageDictionary[indexPath.row]
if indexPath.row == tableFeedCount - 1 && lockoutFeed != true && tableFeedCount == self.allDictionary.count && imageFeedCount == imageDictionary.count{
let dictionary = self.allDictionary[indexPath.row]
let date = dictionary?["date"] as! Double
let date2 = date*100000
let date3 = pow(10,16) - date2
let date4 = String(format: "%.0f", date3)
setUpFeed(starting: date4, queryLimit: UInt(11))
}
}
else if (dictionary?["type_"] as! String) == "Video" {
print("video feed", indexPath.row)
cell.imageView?.layer.borderColor = UIColor.black.cgColor
cell.layer.borderWidth = 1
let imagerView = UIImageView()
imagerView.layer.cornerRadius = 1
imagerView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
imagerView.image = videoDictionary[indexPath.row]
// let vidUIView = UIView()
// vidUIView.tag = indexPath.row
let asf = UITapGestureRecognizer(target: self, action: #selector(ProfileController.playVid2(gestureRecognizer:)))
asf.numberOfTapsRequired = 2
// imagerView.addGestureRecognizer(asf)
let adsf = UITapGestureRecognizer(target: self, action: #selector(ProfileController.playVid(gestureRecognizer:)))
adsf.numberOfTapsRequired = 1
adsf.require(toFail: asf)
// imagerView.addGestureRecognizer(adsf)
cell.contentView.addGestureRecognizer(asf)
cell.contentView.addGestureRecognizer(adsf)
cell.contentView.frame = CGRect(x: 0, y: 0, width: 200, height: 200)
cell.contentView.addSubview(imagerView)
//cell.contentView.addSubview(vidUIView)
if indexPath.row == tableFeedCount - 1 && lockoutFeed != true && tableFeedCount == self.allDictionary.count && videoFeedCount == videoDictionary.count{
let dictionary = self.allDictionary[indexPath.row]
let date = dictionary?["date"] as! Double
let date2 = date*100000
let date3 = pow(10,16) - date2
let date4 = String(format: "%.0f", date3)
setUpFeed(starting: date4, queryLimit: UInt(11))
}
}

It's unclear if that code is in a view controller or in a UITableViewCell subclass. In any case, you will want to use a UITableViewCell subclass for your cells and do cleanup tasks in prepareForReuse:
override func prepareForReuse() {
super.prepareForReuse()
imagerView.image = nil
}
This will involve removing any data from the cell that you don't want carried over into the cell when it is reused. Clearing images from image views, hiding views that won't be shown for all cell types, etc.
Another solution would be to have multiple cell classes and load the appropriate cell class based on the data type it is responsible for displaying. This will simplify some of the code above and may help to prevent reuse, but it will require a significant refactor by the looks of things.
