ios - 3DTouch 上的 SFSafariViewController 问题(弹出状态)

Question

我正在尝试在 TableViewController 中实现 Peek 和 Pop 功能，这样当我 3DTouch 任何单元格时，它都会显示 SFSafariViewController 的预览他们会带我去敲他们。 peek 功能工作得很好，但一旦它进入弹出状态，它就不会在 desired state 中提供 SFSafariViewController但最终显示的是前一个 View 中的导航 Controller ，以及一个显示 SFViewController (Image Here) 的尺寸不佳的 View .

这就是我在 TableViewController 中编写 peek 和 pop 功能的方式:

extension MyBlogsTableViewController: UIViewControllerPreviewingDelegate {

func previewingContext(previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController? {
    if let indexPath = tableView.indexPathForRowAtPoint(location) {

            let cell = tableView.cellForRowAtIndexPath(indexPath) as! MyBlogsTableViewCell

            let destinationViewController = SFViewControllerToExplore(indexPath.row)
            destinationViewController.preferredContentSize = CGSize(width: 0.0, height: 0.0)

            previewingContext.sourceRect = cell.frame

            return destinationViewController
    }
    return nil
}

func previewingContext(previewingContext: UIViewControllerPreviewing, commitViewController viewControllerToCommit: UIViewController) {
    navigationController?.pushViewController(viewControllerToCommit, animated: true)
}

private func touchedView(view: UIView, location: CGPoint) -> Bool {
    let locationInView = view.convertPoint(location, fromView: tableView)
    return CGRectContainsPoint(view.bounds, locationInView)
}

private func SFViewControllerToExplore(index: Int) -> UIViewController {
    var destinationController: SFSafariViewController

    destinationController = SFSafariViewController(URL: NSURL(string: identifierOfLinks[index])!, entersReaderIfAvailable: true)

    return destinationController
}

}

想通了。所以在下面的代码中:

func previewingContext(previewingContext: UIViewControllerPreviewing, commitViewController viewControllerToCommit: UIViewController) {
     navigationController?.pushViewController(viewControllerToCommit, animated: true)
}  

我实际上不应该使用 pushViewController，我应该使用 presentViewController

更正后的代码:

func previewingContext(previewingContext: UIViewControllerPreviewing, commitViewController viewControllerToCommit: UIViewController) {
     navigationController?.presentViewController(viewControllerToCommit, animated: true, completion: nil)
}
