ios - 3D Touch 卡住了我的应用程序

Question

也许我的问题等于:

Force Touch animation freezes if gently touched

App is freezing in 'peek and pop' implementation in iPhone 6s

1) 没有“错误”的强制触摸:创建一个 UITransitionView 层来预览我的 View Controller 。效果很好。

2) 用“bug”强制触摸:当我轻轻点击按钮时，创建了 UITransitionView 层，但它是透明的(没有内容)，此时我无法与我的应用程序交互(因为顶层是“空的”)。

更新:

代码:

HomeViewController

extension HomeViewController: UIViewControllerPreviewingDelegate {

    func previewingContext(previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController? {
        if #available(iOS 9.0, *) {
            previewingContext.sourceRect = balanceButton!.bounds
        }

        let balanceViewController = UIStoryboard.balanceViewController()
        balanceViewController.delegate = self
        balanceViewController.account = account
        balanceViewController.preferredContentSize = CGSize(width: 0.0, height: 118)
        navigationController?.preferredContentSize = CGSize(width: 0.0, height: 118)

        return balanceViewController
    }

    func previewingContext(previewingContext: UIViewControllerPreviewing, commitViewController viewControllerToCommit: UIViewController) {
        let balanceViewController = viewControllerToCommit as! BalanceViewController
        balanceViewController.shouldPresentCompleteMode = true
        navigationController?.pushViewController(balanceViewController, animated: true)
    }

}

在 BalanceViewController 上:

@available(iOS 9.0, *)
    override func previewActionItems() -> [UIPreviewActionItem] {
        let action2 = UIPreviewAction(title: "Últimos 5 dias úteis", style: .Default) { (action, viewController) in
           self.delegate?.balanceViewControllerFilterDidSelected(.FiveDays)
        }
        let action3 = UIPreviewAction(title: "action", style: .Default) { (action, viewController) in
            self.delegate?.balanceViewControllerFilterDidSelected(.FiftyDays)
        }
        let action4 = UIPreviewAction(title: "action", style: .Default) { (action, viewController) in
            self.delegate?.balanceViewControllerFilterDidSelected(.ThirtyDays)
        }
        let action5 = UIPreviewAction(title: "action", style: .Default) { (action, viewController) in
            self.delegate?.balanceViewControllerFilterDidSelected(.SixtyDays)
        }

        return [action2, action3, action4, action5]
    }

更新 2:

当我切换到另一个应用程序并切换回我的应用程序时..我的设备会振动并查看，但会再次卡住。

谁能帮帮我？

问题已解决

我找到了解决方案。问题是“冗余的”Peek 和 Pop 注册。我正在注册:

1) 调用registerForPreviewingWithDelegate(self, sourceView: view)在 viewDidLoad()

2)

也许它们相互冲突，为了解决这个问题，我删除了 Storyboard转场。
