I am new to Swift language and I want to implement a swipe gesture to my image so that I can change the page with it. For example when you received a whatsapp notification on any iPhone home screen. But when I am adding swipe gesture programmatically it gives me this error.

let rightSwipe = UISwipeGestureRecognizer(target: swipeImage, action: Selector("handleSwipe:"))

rightSwipe.direction = .Right

view.addGestureRecognizer(rightSwipe)

the error is when I am giving the id of my UIImage named swipeImage it gives me unrecognized selector sent to instance but when I give it named self it doesn't give me an error. But i want to add swipe gesture to my image. I hope I explained my problem.

Edit 1: Eventhough i changed the target to self.swipeImage it gives me the same error. Also I added addGestureRecognizer to my image by changing view to swipeImage but it does not work too

Thanks.

The target is the object wants to have the action called on it when the swipe happens.

It is not possible to add a gesture recognizer to a UIImage. They need to be added to UIView subclasses like UIImageView. You just need to use the addGestureRecognizer: method on the image view to add it.

let rightSwipe = UISwipeGestureRecognizer(target: self, action: Selector("handleSwipe:"))

imageView.addGestureRecognizer(rightSwipe)

  • I did it but it does not take the action at all. I put a label and changing it when the swipe method called and when I am trying to swipe right my label does not change. By the way thanks for giving an answer – Burak Gumus Mar 23 '16 at 16:22
