Page ViewController with 4 viewControllers - 如何将视图 2 设置为初始 viewController？

Question

我创建了一个带有四个视图控制器的 pageViewController。

现在的顺序是：

VC1、VC2、VC3、VC4：

var pageControl = UIPageControl()
var pendingPage: Int?

lazy var viewControllerList: [UIViewController] = {
    let sb = UIStoryboard(name: "Main", bundle: nil)

    let vc1 = sb.instantiateViewController(withIdentifier: "VC1")
    let vc2 = sb.instantiateViewController(withIdentifier: "VC2")
    let vc3 = sb.instantiateViewController(withIdentifier: "VC3")
    let vc4 = sb.instantiateViewController(withIdentifier: "VC4")

    return [vc1, vc2, vc3, vc4]
}()

如何在应用程序加载时将VC2设置为页面视图控制器的初始视图控制器？所以基本上用户可以向左 "and" 向右滑动以从 VC2 向左滑动到 VC1 或从 VC2 向右滑动到 VC3。

VC1 < VC2 - 这是开始视图控制器 > VC3 > VC4

这是我的 viewDidLoad():

override func viewDidLoad() {
    super.viewDidLoad()

    self.delegate = self
    self.dataSource = self

    if let firstViewController = viewControllerList.first {
        self.setViewControllers([firstViewController], direction: .forward, animated: true, completion: nil)
    }
}

Answer 1

    self.setViewControllers([viewControllerList[1]], direction: .forward, animated: true, completion: nil)
