ios - 导航栏在执行 popViewController 时闪烁黑色

Question

我的应用程序需要反向弹出动画。它的部署目标是 IOS 7。

所以，我已经实现了TRVSNavigationControllerTransition应用程序接口(interface)。

我有默认的半透明导航栏。它成功弹出，但在动画时闪烁黑色。

我附上了实际显示方式的图片。

感谢任何帮助。

谢谢，巴津加。

好的，下面是我用来处理这种情况的解决方案。

反向推 (即从左到右)

CATransition *transition = [CATransition animation];
        transition.duration = 0.3;
        transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault];
        transition.type = kCATransitionFromLeft;
        [transition setType:kCATransitionPush];
        transition.subtype = kCATransitionFromLeft;
        transition.delegate = self;
        [self.navigationController.view.layer addAnimation:transition forKey:nil];

        self.navigationController.navigationBarHidden = NO;
        [self.navigationController pushViewController:<objVC> animated:NO];

然后，反向弹出 (即从右到左)

CATransition *transition = [CATransition animation];
        transition.duration = 0.3;
        transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault];
        transition.type = kCATransitionFromRight;
        [transition setType:kCATransitionPush];
        transition.subtype = kCATransitionFromRight;
        transition.delegate = self;
        [self.navigationController.view.layer addAnimation:transition forKey:nil];

        self.navigationController.navigationBarHidden = NO;
        [self.navigationController popViewControllerAnimated:NO];
