How would I be able to arrange the cells by sections with a custom header
I have code set to arrange the cells in the CartVC by brand(the brand being placed in a Custom Header Cell) in the CartVC when the data is passed from the HomeVC to the CartVC, yet I still can't get my code arrange the cells into sections by brand
so far what Ive does is created an array in my cart to help arrange the cells in the CartVC by their Brand. After the data has been passed from the HomeVC to the CartVC.
basically what im asking is
How would I be arrange the sections by brand in the CartVC after data is passed into the Cart
extension HomeController: UITableViewDelegate, UITableViewDataSource {
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return itemSetup.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "HomeCell") as? HomeCell else { return UITableViewCell() }
let item = itemSetup[indexPath.row]
cell.configure(withItems: item)
// passes data to the Cart Cells in the CartVC when ATC Btn is pressed in each HomeCell
cell.addActionHandler = { (option: Int) in
print("Option selected = \(option)")
Tray.currentCart.cartItems.append(item)
item.selectedOption = option
}
return cell
}
}
