Swift 4.2：如何在 ViewController 中嵌入 UIPageControl（没有 Storyboard）？

Question

Does anyone have an example of how to embed a PageController within a ViewController without using a xib or storyboard?

Is using a UIPageControl the right approach to build the following?

Answer 1

The standard technique is along these lines:

    let pvc = UIPageViewController(transitionStyle: .scroll, navigationOrientation: .horizontal)
    self.addChild(pvc)
    self.view.addSubview(pvc.view)
    pvc.view.frame = // whatever
    pvc.didMove(toParent: self)
    pvc.setViewControllers( //...
    pvc.dataSource = // ...
