Block size image when I enlarge the view
I have a view and within an image that works as a button. I would like to know if there is a way to lock the size of the button so that when I zoom in, the view remains small and does not enlarge with the view..

@TamásSengel I do not have to center the image, but make sure that it does not enlarge when I enlarge the view in which it is inserted

That's what.center(and also.left,.rightetc.) does. Try it out.

I thought it was hard to manager in the beginning. But finally, if you put the imageView in a UIScrollView, It's not hard to achieve.
The idea is move the buttonView outside of imageView during zooming and when zoom is over, put it back to imageView to pretend nothing happened. I know it's too verbose in programming but actually it works perfectly for your case.
var originalCenter : CGPoint! // The center of ButtonView in imageView.
//All functions are from the UIScrollViewDelegate.
func viewForZooming(in scrollView: UIScrollView) -> UIView?{
originalCenter = buttonView.center // remember the original position.
return imageView
}
func scrollViewWillBeginZooming(_ scrollView: UIScrollView, with view: UIView?) {
buttonView.frame = imageView.convert(buttonView.frame, to: scrollView)
scrollView.addSubview(buttonView)//add to superView of imageImage.
}
func scrollViewDidZoom(_ scrollView: UIScrollView){
buttonView.center = imageView.convert(originalCenter, to: scrollView) //During Zooming, update the buttonView in ScrollView.
}
func scrollViewDidEndZooming(_ scrollView: UIScrollView, with view: UIView?, atScale scale: CGFloat){
buttonView.frame = imageView.convert(buttonView.frame, from: scrollView)
imageView.addSubview(buttonView) //put it back.
}
I know it's better to use a parameter to control such operation. But I have-not found one according to public APIs. Maybe there is a better way, hope this one is your answer too.
