swift - 快速重置 hidesBarsOnSwipe

Question

我必须在哪里以及如何重置 hidesBarsOnSwipe？我在我推送的 View Controller 中设置了该选项，并希望为执行推送的 View Controller 重置它。到目前为止，我尝试的是在推送 ViewController 的 viewDidDisappear 和 viewDidLoad 中将 hidesBarsOnSwipe 设置为 false。

导航栏仍在消失。

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    if (!visiblePOIs.isEmpty) {
        let beaconInfo = visiblePOIs[indexPath.item]
        var controller = storyboard!.instantiateViewControllerWithIdentifier("DetailController")! as! DetailController
        controller.setup(beaconInfo)
        self.parentViewController!.navigationController?.pushViewController(controller, animated: true)
    }
}

细节 Controller

override func viewDidLoad() {
    super.viewDidLoad()
    webView.delegate = self
    navigationController?.hidesBarsOnSwipe = true
    self.automaticallyAdjustsScrollViewInsets = false
}

下一个viewcontroller写入viewDidload

First Vc

override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
self.navigationController?.hidesBarsOnSwipe = true
}

Second VC
 override func viewWillAppear(animated: Bool) {
 super.viewWillAppear(animated)
 self.navigationController?.hidesBarsOnSwipe = false
 self.navigationController?.setNavigationBarHidden(false, animated:   true)
 }

我希望它的作品
