ios - 如何删除弹出 UIViewController 中的 UIParallaxDimmingView？

Question

我有一个 UIViewController vc1 被推送到 UIViewController vc2 之后。vc1和vc2都是透明背景

问题:当我尝试使用交互式弹出手势(从边缘平移)弹出 vc2 时，在我的 View 堆栈中出现神秘的 UIParallaxDimmingView 这使我的堆栈变暗(在透明 View Controller 下有一个背景图片)。一旦我松开手指、取消或完成过渡，它就会再次变得清晰/透明。

如何禁用/删除 UIParallaxDimmingView 或将其设置为透明？

如果当您尝试使用交互式弹出手势(从边缘平移)弹出 VC 时它正在推送 VC(仍在动画)，则应用程序可能会被卡住。这可以帮助您:

/ set gesture no when pushViewController /
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.interactivePopGestureRecognizer.enabled = NO;
    }

    [super pushViewController:viewController animated:animated];
}

/ set gesture yes when showViewController /
- (void)navigationController:(UINavigationController )navigationController didShowViewController:(UIViewController )viewController animated:(BOOL)animated
{
    if ([navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        navigationController.interactivePopGestureRecognizer.enabled = YES;
    }

    / if rootViewController, set delegate nil /
    if (navigationController.viewControllers.count == 1) {
        navigationController.interactivePopGestureRecognizer.enabled = NO;
        navigationController.interactivePopGestureRecognizer.delegate = nil;
    }
}
