UITableView - registerClass with Swift

Question

Is anyone else having an issue using the tableView.registerClass method with Swift?

It no longer comes in code completion for me (nor can I use it if manually typed) but it is still in the headers...

Answer 1

Swift 4 and 4.1. making generic methods it is very easy to register and dequeue table cell.

       override func viewDidLoad() {
                super.viewDidLoad()
                self.tblView.register(CellProfileOther.self) // cell class name
       }
        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
                let cell: CellProfileOther = tableView.dequeueReusableCell(forIndexPath: indexPath)
                return cell
            }
        extension UITableView {
        func register<T:UITableViewCell>(_: T.Type) where T: ReusableView, T: NibLoadableView {
                let bundle = Bundle(for: T.self)
                let nib = UINib(nibName: T.nibName, bundle: bundle)
                self.register(nib, forCellReuseIdentifier: T.defaultReuseIdentifier)
            }
        func dequeueReusableCell<T:UITableViewCell>(forIndexPath indexPath: IndexPath) -> T where T: ReusableView {
                guard let cell = self.dequeueReusableCell(withIdentifier: T.defaultReuseIdentifier, for: indexPath) as? T else {
                    fatalError("Could not dequeue cell with identifier: \(T.defaultReuseIdentifier)")
                }
                return cell
            }
        }

        protocol ReusableView: class {
            static var defaultReuseIdentifier: String { get }
        }

        protocol NibLoadableView: class {
            static var nibName: String { get }
        }

        extension ReusableView where Self: UIView {
            static var defaultReuseIdentifier: String {
                return String(describing: Self.self)
            }
        }    
        extension NibLoadableView where Self: UIView {
            static var nibName: String {
                return String(describing: Self.self)
            }
        }

   // Here is cell class 
    class CellProfileOther: UITableViewCell, ReusableView, NibLoadableView  {
    }

For swift 4

self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")

Answer 3

For Swift 2.2 Register For Default Cell From Class

self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "DefaultCell")

For Swift 3.0 Register For Default Cell From Class

self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "DefaultCell")

For Swift 2.2 Register For Default Cell From Nib

self.tableView.registerNib(UINib(nibName: "CustomCellName", bundle: nil), forCellReuseIdentifier: "CustomCellIdentifer")

For Swift 3.0 Register For Default Cell From Nib

self.tableView.registerNib(UINib(nibName: "CustomCellName", bundle: nil), forCellReuseIdentifier: "CustomCellName")

Note: Storyboard created cell is called prototype cell and have some procedure to register prototype cell like Nib.And Don't forget to set the cell identifier like below.

Answer 4

Swift has once again renamed it to

tableView.register(UITableViewCell.self, forCellReuseIdentifier:"DefaultCell")

Really don't understand why they bothered so much about this particular naming

Answer 5

For swift 3 refer this. It works!

Inside you viewdidload function

self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "LabelCell")

Answer 6

Switching the order in which I called registerNib and registerClass worked for me!

For some reason my app crashed when I had:

...registerNib.....

...registerClass...

But ran fine when I had:

...registerClass...

...registerNib.....

Hope that helps some of you.
