UITableView - registerClass with Swift

Ios Swift Uitableview Registerclass

Ios Problem Overview

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...

Solution 1 - Ios

It works for me perfectly.

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

Exactly as I have it above.

Solution 2 - Ios

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.

Solution 3 - Ios

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

Solution 4 - Ios

Updated for Swift 5

> Register TableView Cell in viewDidLoad If you are using Default Cell

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

> Register TableView Cell in viewDidLoad If you are using Custom Nib/XIB Cell

tableView.register(UINib(nibName: "MyCustomCell", bundle: nil), forCellReuseIdentifier: "MyCustomCell")

Solution 5 - Ios

I prefer to use TableViewCell.self to generate the identifier string. It can reduce the typing error.

tableView.register(MyCell.self, forCellReuseIdentifier: String(describing: MyCell.self))

Solution 6 - Ios

For swift 4

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

Solution 7 - Ios

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 3 refer this. It works!

Inside you viewdidload function

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

Solution 9 - Ios

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:
