UIPageViewController与不同的ViewControllers

Question

我想使用UIPageViewController和拖车按钮（next和preve）来显示7个具有不同内容的View Controller，这是我在实现UIPageViewController后的故事板。

我的问题是如何将这些视图控制器放在UIPageViewController中？

Answer 1

Swift中的答案：

调用setViewControllers方法，在你的UIPageVC实例的viewDidLoad中定义你的第一个VC，方向等：

<div class="header row">
  <div class="large-12 columns frontpage-header-content">
    <div class="snirky-snark-box">
      <h4>Vi arbeider med å bygge kompetanse, spre kunnskap og positiv energi i kreftsaken</h4>
      <button type="button" class="button">Støtt kreftsaken</button>
    </div>
    <div class="frontpage-header-image">
      <img src="http://placehold.it/800x150">
    </div>
  </div>

  <div class="header-title-bar">
    <div class="row">
      <div class="large-12 columns">
        <div class="title-bar">
          <div class="title-bar-left">
            <img src="<?php echo get_template_directory_uri(); ?>/assets/images/menu-icon.svg">
            <button class="menu-icon" type="button" data-open="offCanvasLeft"></button>
            <span class="title-bar-title">Meny</span>
          </div>
          <div class="title-bar-right">
            <span class="title-bar-title">Støtteforeningen for Kreftrammede</span>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>
<!-- /.header -->

使用UIPageViewControllerDataSource协议方法定义当前viewController之前和之后的页面，以及视图控制器计数和索引。

override func viewDidLoad() {
    super.viewDidLoad()
    dataSource = self
    let vc = storyboard!.instantiateViewController(withIdentifier: "whatever storyboard id your first VC is")
    setViewControllers([vc],
                       direction: .forward,
                       animated: false,
                       completion: nil)
}
