swift uitapgesturerecognizer pass parameters

Question

I have a lot of Buttons created programmatically and that can change anytime. my tap gesture :

let apriVideoGesture = UITapGestureRecognizer(target: self, action: #selector(PrincipaleController.apriVideo(_:)))
cont.addGestureRecognizer(apriVideoGesture)

func apriVideo(sender : UITapGestureRecognizer){

}

how can i pass parameters? somethig like this :

let apriVideoGesture = UITapGestureRecognizer(target: self, action: #selector(PrincipaleController.apriVideo(stringa : "ciao")))
cont.addGestureRecognizer(apriVideoGesture)

func apriVideo(sender : UITapGestureRecognizer, stringa : String){

}

sorry for bad english, i'm italian

Answer 1

First of all, if you are using button then why are you adding tap gesture? You can add target to it as

btn.addTarget(self, action: #selector(self.btnPressed(_:)), forControlEvents: .TouchDragInside)

But still you can achieve you goal using tap gesture as

Using UIView as u have insisted

    class ViewController: UIViewController {

    let arrayOfSongsURL: [String] = []
    let startingTag = 100

    override func viewDidLoad() {
        super.viewDidLoad()
        let height : CGFloat = 100
        let width : CGFloat = 100
        (arrayOfSongsURL as NSArray).enumerateObjectsUsingBlock { (url, index, finished) -> Void in
            
            let v = UIView(frame: CGRectMake(0, CGFloat(index) * height, width, height))
            v.tag = self.startingTag + index
            
            v.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(self.handleTapGesture(_:))))
            self.view.addSubview(v)
        }
        // Do any additional setup after loading the view, typically from a nib.
    }
    
    
    @objc func handleTapGesture(gesture : UITapGestureRecognizer)
    {
        let v = gesture.view!
        let tag = v.tag
        let songURL = arrayOfSongsURL[tag - startingTag]
        
        //Do what you want to do with songURL
    }
}
