Different sizes of scrollview pages - ios

Question

I like to set one page from my UIScrollView bigger than the others. The last page should be the same size like the whole UIView, is that possible?
That's my unfinished code:
self.scrollView.frame = CGRect(x: 0, y: 0, width: self.scrollView.frame.width, height: self.scrollView.frame.height)
let scrollviewHeight = self.scrollView.frame.height
let scrollviewWidth = self.scrollView.frame.width
let viewHeight = self.view.frame.height
let viewWidth = self.view.frame.width
let imgOne = UIImageView(frame: CGRect(x: 0, y: 0, width: scrollviewWidth, height: scrollviewHeight))
let imgTwo = UIImageView(frame: CGRect(x: scrollviewWidth, y: 0, width: scrollviewWidth, height: scrollviewHeight))
let imgTree = UIImageView(frame: CGRect(x: scrollviewWidth*2, y: 0, width: scrollviewWidth, height: scrollviewHeight))
let feedbackView = UIView(frame: CGRect(x: scrollviewWidth*3, y: 0, width: viewWidth, height: viewHeight))
imgOne.image = UIImage(named: "preview1")
imgTwo.image = UIImage(named: "preview2")
imgTree.image = UIImage(named: "preview3")
self.scrollView.addSubview(imgOne)
self.scrollView.addSubview(imgTwo)
self.scrollView.addSubview(imgTree)
self.scrollView.addSubview(feedbackView)
self.addChildFeedBack(feedbackView: feedbackView)
self.scrollView.contentSize = CGSize(width: self.scrollView.frame.width * 4, height: self.scrollView.frame.height)
self.scrollView.isPagingEnabled = true
The feedbackView is the one, which should be the biggest.

I don't know if this will give you the type of result you want, but something to try...
Instead of adding feedbackView to your scrollView, add another UIScrollView as the 4th subview, and then add feedbackView as a subview of that scroll view:
// your original setup code
self.scrollView.frame = CGRect(x: 0, y: 0, width: self.scrollView.frame.width, height: self.scrollView.frame.height)
let scrollviewHeight = self.scrollView.frame.height
let scrollviewWidth = self.scrollView.frame.width
let viewHeight = self.view.frame.height
let viewWidth = self.view.frame.width
let imgOne = UIImageView(frame: CGRect(x: 0, y: 0, width: scrollviewWidth, height: scrollviewHeight))
let imgTwo = UIImageView(frame: CGRect(x: scrollviewWidth, y: 0, width: scrollviewWidth, height: scrollviewHeight))
let imgTree = UIImageView(frame: CGRect(x: scrollviewWidth*2, y: 0, width: scrollviewWidth, height: scrollviewHeight))
let feedbackView = UIView(frame: CGRect(x: scrollviewWidth*3, y: 0, width: viewWidth, height: viewHeight))
imgOne.image = UIImage(named: "preview1")
imgTwo.image = UIImage(named: "preview2")
imgTree.image = UIImage(named: "preview3")
self.scrollView.addSubview(imgOne)
self.scrollView.addSubview(imgTwo)
self.scrollView.addSubview(imgTree)
// don't add feedbackView to scrollView
// self.scrollView.addSubview(feedbackView)
// instead, create another scroll view,
// add feedbackView to that scroll view,
// and add that scroll view as the 4th "page" in scrollView
let fbScrollView = UIScrollView(frame: CGRect(x: scrollviewWidth*3, y: 0, width: scrollviewWidth, height: scrollviewHeight))
// just so we can see where it is during development
fbScrollView.backgroundColor = .purple
// feedbackView will now be in its own scroll view, so
// set its origin to 0,0
feedbackView.frame.origin = CGPoint.zero
fbScrollView.addSubview(feedbackView)
fbScrollView.contentSize = feedbackView.frame.size
// add the new scroll view to the "paging" scrollView
self.scrollView.addSubview(fbScrollView)
// and the rest of your setup
self.addChildFeedBack(feedbackView: feedbackView)
self.scrollView.contentSize = CGSize(width: self.scrollView.frame.width * 4, height: self.scrollView.frame.height)
self.scrollView.isPagingEnabled = true
