Reset hidesBarsOnSwipe in swift - swift

Question

Where and how do I have to reset hidesBarsOnSwipe? I set the option in a View Controller which I push and want to reset it for the View Controller which did the push. What I tried until now is setting hidesBarsOnSwipe to false in the viewDidDisappear and in the viewDidLoad of the pushing ViewController.
The Navigationbar is still disappearing.
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)
}
}
DetailController
override func viewDidLoad() {
super.viewDidLoad()
webView.delegate = self
navigationController?.hidesBarsOnSwipe = true
self.automaticallyAdjustsScrollViewInsets = false
}

Answer 1

next view controller write in 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)
}
I hope its works

I had your exact problem. Here's how I solved it. (You can adapt this based on your needs.)
class MyViewController: UITableViewController {
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
//Correct the nav bar state unwinding from segues
self.navigationController?.hidesBarsOnSwipe = true
}
override func willMoveToParentViewController(parent: UIViewController?) {
super.willMoveToParentViewController(parent)
//Toggle the auto-hiding nav bar when this view gets added/removed from the nav controller
self.navigationController?.hidesBarsOnSwipe = !self.navigationController!.hidesBarsOnSwipe
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
super.prepareForSegue(segue, sender: sender)
//Reset the nav bar to visible when segueing to another view
self.navigationController?.navigationBarHidden = false
self.navigationController?.hidesBarsOnSwipe = false
}
}
This approach allows you to limit the functionality of the auto-hiding feature to the desired view controller without adding code to all associated view controllers.
