}

• **UIPageControl
  实现滑动改变某个位置的颜色改变
  

相关代码的实现

import UIKit
class MyPageControl: UIPageControl {
    override init(frame: CGRect) {
    super.init(frame: frame)self.numberOfPages = 4//不是当前页面的小点颜色self.pageIndicatorTintColor = UIColor.gray//当前页面的小点颜色self.currentPageIndicatorTintColor = UIColor.red}required init?(coder: NSCoder) {
    fatalError("init(coder:) has not been implemented")}
}

class MyScrollView: UIScrollView,UIScrollViewDelegate{
    override init(frame: CGRect) {
    super.init(frame: frame)self.contentSize = CGSize(width: self.frame.width * 4, height: self.frame.height - 100)self.showsHorizontalScrollIndicator = falseself.isPagingEnabled = trueself.delegate = self}required init?(coder: NSCoder) {
    fatalError("init(coder:) has not been implemented")}
}

func setupView() {
    self.view.addSubview(self.pageControl)self.view.addSubview(self.scrollView)let viewSize = CGRect(x: 100, y: 100, width: self.view.frame.width - 200, height: self.view.frame.height - 300)for i in 0...3 {
    let view = UIView.init(frame: CGRect.init(x: viewSize.width * CGFloat(i), y: 0, width: viewSize.width, height: viewSize.height - 300))if i == 0 {
    view.backgroundColor = UIColor.black}else if i == 1{
    view.backgroundColor = UIColor.red}else if i == 2{
    view.backgroundColor = UIColor.green}else{
    view.backgroundColor = UIColor.blue}self.scrollView.addSubview(view)}}
