UIScrollView not scrolling in Swift

Question

My UIScrollView won't scroll down. I don't know why. I already followed Apple documentation regarding to this issue.

@IBOutlet weak var scroller: UIScrollView!      override func viewDidLoad() {     super.viewDidLoad()      // Do any additional setup after loading the view.  }  override func viewDidLayoutSubviews() {     scroller.scrollEnabled = true     // Do any additional setup after loading the view     scroller.contentSize = CGSizeMake(400, 2300) } 

Answer 1

You need to set the frame of your UIScrollView so that it is less than the contentSize. Otherwise, it won't scroll.

Also, I would recommend that you add the following to your viewDidLoad method:

scroller.contentSize = CGSize(width: 400, height: 2300) 

Answer 2

Alot of the time the code is correct if you have followed a tutorial but what many beginners do not know is that the scrollView is NOT going to scroll normally through the simulator. It is suppose to scroll only when you press down on the mousepad and simultaneously scroll. Many Experienced XCode/Swift/Obj-C users are so use to doing this and so they do not know how it could possibly be overlooked by beginners. Ciao :-)

@IBOutlet weak var scrollView: UIScrollView! override func viewDidLoad() { super.viewDidLoad() view.addSubview(scrollView) // Do any additional setup after the view }  override func viewWillLayoutSubviews(){ super.viewWillLayoutSubviews() scrollView.contentSize = CGSize(width: 375, height: 800) } 

This code will work perfectly fine as long as you do what I said up above
