ios - 如何在 iOS9 中禁用 interactivePopGestureRecognizer

Question

我需要在我的应用程序中禁用 interactivePopGestureRecognizer，我做到了

- (void)viewDidAppear:(BOOL)animated
{

    [super viewDidAppear:animated];

    // Disable iOS 7 back gesture

 if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) 
{

 self.navigationController.interactivePopGestureRecognizer.enabled = NO;

        self.navigationController.interactivePopGestureRecognizer.delegate = self;

    }
}


- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];

    // Enable iOS 7 back gesture

    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)])
 {

 self.navigationController.interactivePopGestureRecognizer.enabled = YES;

self.navigationController.interactivePopGestureRecognizer.delegate = nil;

 }
}


- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer

{

 return NO;
}

它适用于“iOS8”，我在“iOS9”上遇到问题。

如果你想禁用全局 interactivePopGestureRecognizer，你可以在创建 navigationController 后禁用它，如下所示。

UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:rootVC];
nav.interactivePopGestureRecognizer.enabled=NO;
