In one of my games I am using a UICollectionView as the level select menu. I recently added a UIPageControl to it programatically.
/// Page control
func setupPageControl() {
pageControl.hidesForSinglePage = true
pageControl.numberOfPages = DataSource.worlds
pageControl.translatesAutoresizingMaskIntoConstraints = false
pageControl.currentPageIndicatorTintColor = DataSource.pageControlColors[pageControl.currentPage]
pageControl.pageIndicatorTintColor = UIColor.white.withAlphaComponent(0.8)
pageControl.addTarget(self, action: #selector(didPressPageControl), for: .valueChanged)
view.addSubview(pageControl)
let leading = NSLayoutConstraint(item: pageControl, attribute: .leading, relatedBy: .equal, toItem: view, attribute: .leading, multiplier: 1, constant: 0)
let trailing = NSLayoutConstraint(item: pageControl, attribute: .trailing, relatedBy: .equal, toItem: view, attribute: .trailing, multiplier: 1, constant: 0)
let bottomConstant = Device.isPad ? view.frame.width / 9 : view.frame.width / 17
let bottom = NSLayoutConstraint(item: pageControl, attribute: .bottom, relatedBy: .equal, toItem: view, attribute: .bottom, multiplier: 1, constant: -bottomConstant)
view.addConstraints([leading, trailing, bottom])
}
Everything is fine on iOS but on tvOS the PageController has a translucent background that stretches all across the screen.
How can I turn this off? I tried setting the pageControl background color but that does not seem to work.
As usual just when I post a question I find the answer a minute later.
You can remove the background on tvOS by calling this
#if os(tvOS)
for subview in pageControl.subviews {
let effectView = subview as? UIVisualEffectView
effectView?.removeFromSuperview()
}
#endif
