Lingering gesture recognizer when setting userInteractionEnabled = NO #36

Closed slkandy closed 11 years ago

When you try to temporarily disable swiping by calling:

self.layeredNavigationController.userInteractionEnabled = NO;

The swiping will not be recognized (as expected), but FRLayeredNavigationController's gesture recognizer is not fully removed.

In my application I need to disable swiping and display a transparent UIView that allows for freehand drawing. I was having issues while drawing because touchesCancelled was getting called unexpectedly on my transparent UIView, which prevented the user from drawing anything.

I was able to fix this by calling removeGestureRecognizer in FRLayeredNavigationController's detachGestureRecognizer method:

- (void)detachGestureRecognizer
{
    [self.view removeGestureRecognizer:self.panGR];
    [self.panGR removeTarget:self action:NULL];
    self.panGR.delegate = nil;
    self.panGR = nil;
}
