UITableView inside UIView in Swift 3.0

Question

I have a problem when put a UITableView into UIView .

I set a delegate and datasource and implement all methods.

This is my UIView Class.

@objc class ChooserView: UIView, UITableViewDelegate, UITableViewDataSource {


@IBOutlet weak var backgroundView: UIView!
@IBOutlet weak var showView: UIView!
@IBOutlet weak var tableView: UITableView!    

public class func createChooserView() -> ChooserView {

    var view: ChooserView!
    view = Bundle.main.loadNibNamed(String(describing: ChooserView.self), owner: self, options: nil)?.first as! ChooserView

    _ = MLAutolayouts.fillContainer(UIApplication.shared.keyWindow!.subviews.first!, view: view)

    //Register cell nib
    view.tableView.register(UINib(nibName: "PhoneCell", bundle: nil), forCellReuseIdentifier: "PhoneCell")

    return view
    }

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 1
    }

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: String(describing: PhoneCell.self)) as! PhoneCell

    return cell
    }

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    print("TAP...")
   } 
}

And this is the outles

When run my app. I get this error

   -[UIView tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x7fded2e772d0

Log img.

Any idea...

Thanks.

Answer 1

Connect IB of dataSource and delegate to ChooserView instead of any other view.

Just right click on your table view and Follow the attached gif for connecting IB properly :

首先，您已经从情节提要中应用了插座，并且也在代码中进行了指定。这是没有必要的;其次，您的表中是否有包含标签或按钮的自定义类？如果您错过了与IBoutlet的任何连接，则通常会发生此问题情节提要或同一插座的指定2个连接检查一次。
