UIGestureRecognizer on UIImageView

Question

I have a UIImageView, which I want to be able to resize and rotate etc.

Can a UIGestureRecognizer be added to the UIImageView?

Answer 1

Swift 4.2

myImageView.isUserInteractionEnabled = true
let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(imageTapped))
tapGestureRecognizer.numberOfTapsRequired = 1
myImageView.addGestureRecognizer(tapGestureRecognizer)

and when tapped:

@objc func imageTapped(_ sender: UITapGestureRecognizer) {
   // do something when image tapped
   print("image tapped")
}
