ios - self.navigationController.interactivePopGestureRecognizer.enabled = NO;不适用于 iOS 8

Question

我想在滑动 View Controller 时禁用弹出手势，但以下几行在 iOS 8 中不起作用:

self.navigationController.interactivePopGestureRecognizer.enabled = NO;

提前致谢

在您希望禁用它的 View Controller 中，添加以下行:

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

    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.delegate = self;
    }
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.delegate = nil;
    }

}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    return NO;
}
