我的应用程序工作正常,直到我升级到OSX 10.10(Yosemite)和Xcode 6.1.现在每当我捆绑我的应用程序进行分发时,我都会在应用程序的特定位置获得一个sigtrap.这不会发生在模拟器中,或者我将应用程序直接加载到手机上.下面是日志,我可以看到它似乎突破的线但无法弄清楚为什么它在那里打破.

设置:我正在尝试创建一个带有嵌入式UIPageViewController的ViewController,它有4个页面,每个页面都是自己的ViewController.

问题:滚动时总是重复第二个视图.例如,使用View1,View2,View3,View4滚动显示View1,View2,View2,View3,View4然后向后滚动具有此顺序View4,View3,View3,View2,View1即使页面控件准确.

我在网上看了很多教程,包括这里和这里的答案.

这是我的页面视图控制器类:

import UIKit

class HostGamePageViewController: ROLViewController, UIPageViewControllerDelegate, UIPageViewControllerDataSource {

  // Constants
  let ViewControllers: NSArray = ["HostGameTest1", "HostGameTest2", "HostGameTest3", "HostGameTest4"]

  // Properties
  var pageViewController: UIPageViewController!
  var currentViewController: String!

  // UI
  @IBOutlet var pageControl: UIPageControl!

  override func viewDidLoad() {
    super.viewDidLoad()

    pageViewController = storyboard?.instantiateViewControllerWithIdentifier("HGPageViewController") as? UIPageViewController
    pageViewController.delegate = self
    pageViewController.dataSource = self

    let startingViewController = viewControllerAtIndex(0)!
    pageViewController.setViewControllers([startingViewController], direction: UIPageViewControllerNavigationDirection.Forward, animated: false, completion: {done in })

    addChildViewController(pageViewController)
    view.addSubview(pageViewController.view)
    pageViewController.view.frame = view.bounds
    pageViewController.didMoveToParentViewController(self)
    view.gestureRecognizers = pageViewController.gestureRecognizers

    // Setup …
