UIImageView Événement Tactile

vous pouvez utiliser UITapGestureRecognizer ajouté à la UIImageView via addGestureRecognizer

extraits:

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(bannerTapped:)];
singleTap.numberOfTapsRequired = 1;
singleTap.numberOfTouchesRequired = 1;
[iv addGestureRecognizer:singleTap];
[iv setUserInteractionEnabled:YES];

et

- (void)bannerTapped:(UIGestureRecognizer *)gestureRecognizer {
    NSLog(@"%@", [gestureRecognizer view]);
}

Ici je vous montre deux possibilités pour la réalisation que dans Swift:

Première Possibilité

import UIKit

class ViewController: UIViewController {
    @IBOutlet var myUIImageView: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()
        //You can also manually set it through IB 
        //selecting the UIImageView in the storyboard
        //and checking "User Interaction Enabled" checkbox 
        //in the Attributes Inspector panel.
        self.myUIImageView.userInteractionEnabled = true
    }

    //You can choose to use one of the UIResponder methods:
    //touchesBegan, touchesMoved, touchesEnded etc, in order to detect the touch
    //on the UIImageView.
    override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
       let touch: UITouch? = touches.first
       if touch?.view == myUIImageView {
          println("myUIImageView has been tapped by the user.")
       }
       super.touchesEnded(touches, withEvent: event)
    }
}

Deuxième Possibilité

import UIKit

class ViewController: UIViewController {
    @IBOutlet var myUIImageView: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()
        let singleTap = UITapGestureRecognizer(target: self, action: "myUIImageViewTapped:")
        singleTap.numberOfTapsRequired = 1 //Initialized to 1 by default
        singleTap.numberOfTouchesRequired = 1 //Initialized to 1 by default
        self.myUIImageView.addGestureRecognizer(singleTap)
        self.myUIImageView.userInteractionEnabled = true
    }

    func myUIImageViewTapped(recognizer: UITapGestureRecognizer) {
        if(recognizer.state == UIGestureRecognizerState.Ended){
            println("myUIImageView has been tapped by the user.")
        }
    }
}
