Passing arguments to selector in Swift

Question

I\'m programmatically adding a UITapGestureRecognizer to one of my views:

let gesture = UITapGestureRecognizer(target: self, action: #selector(self.handleTap         


        

Answer 1

Just create a custom class of UITapGestureRecognizer =>

import UIKit

class OtherUserProfileTapGestureRecognizer: UITapGestureRecognizer {

    let userModel: OtherUserModel    
    init(target: AnyObject, action: Selector, userModel: OtherUserModel) {
        self.userModel = userModel
        super.init(target: target, action: action)
    }
}

And then create UIImageView extension =>

import UIKit

    extension UIImageView {
    
        func gotoOtherUserProfile(otherUserModel: OtherUserModel) {
            isUserInteractionEnabled = true
            let gestureRecognizer = OtherUserProfileTapGestureRecognizer(target: self, action: #selector(self.didTapOtherUserImage(_:)), otherUserModel: otherUserModel)
            addGestureRecognizer(gestureRecognizer)
        }
        
        @objc internal func didTapOtherUserImage(_ recognizer: OtherUserProfileTapGestureRecognizer) {
            Router.shared.gotoOtherUserProfile(otherUserModel: recognizer.otherUserModel)
        }
    }

Now use it like =>

self.userImageView.gotoOtherUserProfile(otherUserModel: OtherUserModel)
