UITableViewCell Button Vanishes If Screen Is Relatively Small - ios

Question

I'm creating a simple tabbed(3 tab bar items) app using Swift 5 and Xcode 11. Inside the iOS app, which originally had 2 tab bar items, I was thinking of making some themes for my app, and so I did, adding one more tab bar item to my app. I added the themes for the users to select like this, using UITableViewCells and programmatically made buttons:
That's what looks like. At least for big screen sized iPhones. Starting at iPhone 6, everything works fine, like pictured above. But below iPhone 6, like this iPhone 5, the left set of buttons disappear:
It's weird, and I have no idea why the right set of buttons stayed.
This is my UITableViewController:
import UIKit
#objcMembers class CustomViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewWillAppear(_ animated: Bool) {
self.tableView.rowHeight = 138
}
override func tableView(_ tableView: UITableView, titleForHeaderInSection
section: Int) -> String? {
return "Themes"
}
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return SingletonViewController.themes.count
}
// 3
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "themeCell", for: indexPath) as! ThemeCell
var cellyi = UIButton(frame: CGRect(x: 5, y: 5, width: 50, height: 30))
cellyi.tag = indexPath.row + 1
/////////
if cellyi.tag == 1 {
let cellButton1 = UIButton(frame: CGRect(x: 0, y: 5, width: 88, height: 119.5))
cellButton1.translatesAutoresizingMaskIntoConstraints = false
cell.addSubview(cellButton1)
cell.accessoryView = cellButton1
cellButton1.leadingAnchor.constraint(equalTo: cell.leadingAnchor, constant: 10).isActive = true
cellButton1.topAnchor.constraint(equalTo: cell.topAnchor, constant: 10).isActive = true
cellButton1.widthAnchor.constraint(equalToConstant: 88).isActive = true
cellButton1.heightAnchor.constraint(equalToConstant: 119.5).isActive = true
cellButton1.addTarget(self, action: #selector(CustomViewController.backBTN(sender:)), for: .touchUpInside)
cellButton1.setTitle("Classic", for: .normal)
cellButton1.setTitleColor(UIColor.black, for: .normal)
cellButton1.tag = indexPath.row + 1
}else{
let cellButton = UIButton(frame: CGRect(x: 0, y: 5, width: 88, height: 119.5))
cellButton.translatesAutoresizingMaskIntoConstraints = false
cell.addSubview(cellButton)
cell.accessoryView = cellButton
cellButton.leadingAnchor.constraint(equalTo: cell.leadingAnchor, constant: 10).isActive = true
cellButton.topAnchor.constraint(equalTo: cell.topAnchor, constant: 10).isActive = true
cellButton.widthAnchor.constraint(equalToConstant: 88).isActive = true
cellButton.heightAnchor.constraint(equalToConstant: 119.5).isActive = true
tag = indexPath.row - 1
cellButton.setImage(UIImage(named: SingletonViewController.themes[indexPath.row - 1]), for: UIControl.State.normal)
cellButton.addTarget(self, action: #selector(CustomViewController.backBTN(sender:)), for: .touchUpInside)
cellButton.tag = indexPath.row + 1
}
//////////
cell.addSubview(cellyi)
cell.accessoryView = cellyi
cellyi.backgroundColor = UIColor.red
cellyi.addTarget(self, action: #selector(CustomViewController.backBTN(sender:)), for: .touchUpInside)
if UserDefaults.standard.integer(forKey: "like") == 0{
UserDefaults.standard.set(1, forKey: "like")
}
if UserDefaults.standard.integer(forKey: "like") == indexPath.row + 1{
cellyi.backgroundColor = UIColor.green
if indexPath.row + 1 == 1{
self.tabBarController?.tabBar.barTintColor = UIColor(red:0.84, green:0.84, blue:0.84, alpha:1.0)
self.tabBarController?.tabBar.tintColor = UIColor(red:0.21, green:0.56, blue:0.96, alpha:1.0)
}else if indexPath.row + 1 == 2{
self.tabBarController?.tabBar.barTintColor = UIColor.black
self.tabBarController?.tabBar.tintColor = UIColor(red:0.98, green:0.64, blue:0.02, alpha:1.0)
}
}
tableView.allowsSelection = false
return cell
}
#objc func backBTN(sender: UIButton){
UserDefaults.standard.set(sender.tag, forKey: "like")
tableView.reloadData()
}
}
I have viewed some other of the similar questions to this one. Currently, I still haven't found a solution to this. Any help is appreciated
