Scaling the page control will scale the dots, but will also scale the spacing in between them.
pageControl.transform = CGAffineTransform(scaleX: 2, y: 2)
If you want to keep the same spacing between dots, you'll need to transform the dots individually:
pageControl.subviews.forEach {
$0.transform = CGAffineTransform(scaleX: 2, y: 2)
}
However, if you do this in viewDidLoad
, the transform has been reset by the time the view appears, so you should do this in viewDidLayoutSubviews
…
override func viewDidLayoutSubviews() {
pageControl.subviews.forEach {
$0.transform = CGAffineTransform(scaleX: 2, y: 2)
}
}
