Anyway to disable pan gesture sometimes? about ghsidebarnav

[gresrun]

You can remove the pan gesture recognizer from the navigation controller's navigation bar for the views that you wish to disable that feature. You'll have to hold a reference to it (or recreate it) if you want to add it back later.

Thanks, here is what I do:

1. take pretty much everything as the sample code
2. For the root view controller in the navigation controller, I do:

- (void)viewWillAppear:(BOOL)animated {
    // enable pan gesture
    NSArray* gestureRecognizers = [self.navigationController.navigationBar gestureRecognizers];
    for (UIGestureRecognizer *gestureRecognizer in gestureRecognizers) {
        if ([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
            gestureRecognizer.enabled = YES;
            break;
        }
    }
}

1. For other view controllers (wizard-like step by step views), disable the PanGesture in viewDidLoad

    NSArray* gestureRecognizers = [self.navigationController.navigationBar gestureRecognizers];
    for (UIGestureRecognizer *gestureRecognizer in gestureRecognizers) {
        if ([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
            gestureRecognizer.enabled = NO;
            break;
        }
    }

It works OK, but is there any better ways?

That seems about as simple as it can get. The only other thing I can think of is you could make it a method:

- (void)enableSwipeToRevealGesture:(BOOL)enable {
    NSArray* gestureRecognizers = [self.navigationController.navigationBar gestureRecognizers];
    for (UIGestureRecognizer *gestureRecognizer in gestureRecognizers) {
        if ([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
            gestureRecognizer.enabled = enable;
            break;
        }
    }
}

so it doesn't clutter your logic flow.
