How to hide Navigation Bar without losing slide-back ability

Question

I have a UITableView and it has a nav bar(got from UINavigationViewController), it's able to go back by sliding back using a finger.

I tried to hide the nav bar but keep the slide-back ability, code:

- (void)viewWillAppear:(BOOL)animated {     [[self navigationController] setNavigationBarHidden:YES animated:YES]; } 

This successfully hid the nav bar, however, I can no longer slide back to the last screen either.

Is there any way to hide the nav bar but keep the slide-back ability?

Answer 1

Tested with Swift 2 the solution of @gabbler, if you use

self.navigationController?.navigationBar.hidden = true 

Swift 3.0

self.navigationController?.navigationBar.isHidden = true 

instead of

self.navigationController?.navigationBarHidden = true 

the swipe back gesture works like a charm!

Answer 2

Found the solution:

- (void)viewWillAppear:(BOOL)animated {     [super viewWillAppear:animated];     // hide nav bar     [[self navigationController] setNavigationBarHidden:YES animated:YES];      // enable slide-back     if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {         self.navigationController.interactivePopGestureRecognizer.enabled = YES;         self.navigationController.interactivePopGestureRecognizer.delegate = self;     } }   - (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {     return YES; } 

And in .h file, conform to UIGestureRecognizerDelegate
