Disable swipe back gesture in Swift
The following is an easy approach to disabling & re-enabling the swipe back.
Swift 3.x & up
In a viewDidLoad/willAppear/didAppear method add:
navigationController?.interactivePopGestureRecognizer?.isEnabled = false
Just keep in mind that if you do it with viewDidLoad
, then the next time you open the view, it may not be set depending upon whether or not it remains in your stack.
Unless you want it to remain off, you will need to turn it back on when the view is closed via either willMove(toParentViewController:)
or willDisappear
. Your navigationController
will be nil at viewDidDisappear
, so that is too late.
navigationController?.interactivePopGestureRecognizer?.isEnabled = true
A special note on SplitViewControllers:
As pointed out by CompC in the comments, you will need to call the second navigation controller to apply it to a detail view as such:
navigationController?.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
Swift 2.2 & Objective-C
Swift versions 2.x & below:
navigationController?.interactivePopGestureRecognizer?.enabled
Objective-C:
self.navigationController.interactivePopGestureRecognizer.enabled
You could disable it but that would not be to recommended as most iOS users go back by swiping and less by pressing the back button.
If you want to disable it it would be more reasonable to use a modal segue
instead of a push segue which is not that big of a transfer.
If you really want to get rid of the swipe to go back function I would just disable the back button and have a done button on the top right of the screen.
self.navigationController?.navigationItem.backBarButtonItem?.isEnabled = false;
