Scaling current dot of UIPageControl and keeping it centered

Question

I\'ve subclassed UIPageControl in order to have its current dot bigger.

class CustomPageControl: UIPageControl {
    override var currentPage: Int {
        didS         


        

Answer 1

I tried the solution proposed by Cœur in Swift 5 and Xcode 11 and it works fine with a few notes:

• The PageControl element in IB/Storyboard has to be positioned with constraints.
• The dots are slightly off-center but it can be quickly fixed by changing the constant of the last constraint to systemDotDistance * ( CGFloat($0.offset) - (halfCount - 0.5)).
• If the updateConstraints override is never called, you might need to call self.view.setNeedsUpdateConstraints() in the view controller.
