对于每个不将子视图带到前面的iOS Swift

Question

I've added the following extension to UIView :

func bringViewsToFront(views : [UIView]) {
    views.forEach { (view) in
        self.bringSubviewToFront(view)
}

which I use like this:

imageOverlay.bringViewsToFront(views: [v1, v2, v3])

However this doesn't seem to work - whereas the traditional way below does:

imageOverlay.bringSubviewToFront(v1)
imageOverlay.bringSubviewToFront(v2)
imageOverlay.bringSubviewToFront(v3)

Any idea why?

Well, I bet there is not problem with your for each. Just make sure that the views you're passing as parameter are direct subviews (not grandchildren subviews).
