i'm trying to set custom image on page control dots. I have tried a custom class for this ,
class CustomPageControl: UIPageControl {
@IBInspectable var currentPageImage: UIImage?
@IBInspectable var otherPagesImage: UIImage?
override var numberOfPages: Int {
didSet {
updateDots()
}
}
override var currentPage: Int {
didSet {
updateDots()
}
}
override func awakeFromNib() {
super.awakeFromNib()
pageIndicatorTintColor = .clear
currentPageIndicatorTintColor = .clear
clipsToBounds = false
}
private func updateDots() {
for (index, subview) in subviews.enumerated() {
let imageView: UIImageView
if let existingImageview = getImageView(forSubview: subview) {
imageView = existingImageview
} else {
imageView = UIImageView(image: otherPagesImage)
imageView.center = subview.center
subview.addSubview(imageView)
subview.clipsToBounds = false
}
imageView.image = currentPage == index ? currentPageImage : otherPagesImage
}
}
private func getImageView(forSubview view: UIView) -> UIImageView? {
if let imageView = view as? UIImageView {
return imageView
} else {
let view = view.subviews.first { (view) -> Bool in
return view is UIImageView
} as? UIImageView
return view
}
}
}
