我创建了一个带有四个视图控制器的pageViewController .
现在订单是：
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]
}()
当应用程序加载时，如何将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滑动“和”向右滑动从VC2离开到VC1或从VC2到VC3 .
VC1 <VC2 - 这是启动视图控制器> 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)
}
}
