Swift: addGestureRecognizer not work in class

My class:

class SelectBox {
    internal static func openSelector(list:[String: String], parent:UIView){
        print("iosLog HELLO")
        parent.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleClick(sender:))))
    }

    @objc func handleClick(sender: UITapGestureRecognizer) {
        print("iosLog CLICK")
    }
}

Set view :

SelectBox.openSelector(list: AppDelegate.stateList, parent: bgPlaceInto)

After launch print HELLO, but after click on view i get below error :

2018-07-07 18:39:12.298322+0430 Ma[971:260558] [ChatService]: SMT: 2018-07-07 18:39:12.470392+0430 Ma[971:260525] [ChatService]: RCV: 2018-07-07 18:39:12.471851+0430 Ma[971:260591] [ChatService]: RCV: 2018-07-07 18:39:14.674675+0430 Ma[971:260392] *** NSForwarding: warning: object 0x100a9fc70 of class 'Ma.SelectBox' does not implement methodSignatureForSelector: -- trouble ahead Unrecognized selector +[Ma.SelectBox handleClickWithSender:] 2018-07-07 18:39:14.675210+0430 Ma[971:260392] Unrecognized selector +[Ma.SelectBox handleClickWithSender:]

How i can set click listener to view by class?

Thank you

Your openSelector method is static. The word self in a static context, refers to an instance of the surrounding type's meta type. In this case, SelectorBox.Type.

Obviously, SelectorBox.Type does not have a handleClick method. SelectorBox does.

You need to make the openSelector method non-static:

internal func openSelector(list:[String: String], parent:UIView){
    print("iosLog HELLO")
    parent.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleClick(sender:))))
}

Now self refers to the SelectorBox instance.

You can call it like this:

// declare this at class level:
let box = SelectorBox()

// call the method like this
box.openSelector()

EDIT: Your class should look like this:

class ViewControllerPage: UIViewController, UITableViewDelegate, UITableViewDataSource { 
    @IBOutlet var bgGenderInto: UIView!
    let box = SelectBox()  
    override func viewDidLoad() { 
        super.viewDidLoad() 
        box.openSelector(list: AppDelegate.genderList, parent: bgGenderInto) 
    }
}
