Custom Push Segue删除故事板中的导航栏和标签栏

Question

我在自定义Segue中定义了以下内容，让我们称之为SegueX：

@interface SegueX : UIStoryboardSegue
@end

@implementation SegueX

- (void)perform
{
    CATransition* transition = [CATransition animation];

    transition.duration = 0.3;
    transition.type = kCATransitionFade;

    [[self.sourceViewController navigationController].view.layer addAnimation:transition forKey:kCATransition];
    [[self.sourceViewController navigationController] pushViewController:[self destinationViewController] animated:NO];
}

@end

在我的故事板中，我刚刚将标准Push segue更改为SegueX。出于某种原因，这将删除我的导航栏和标签栏。此外，我在自定义segue之后在故事板中定义的所有UIBarButtonItem都在运行时隐藏。我该如何解决？我希望它不是这样的......

在更改为自定义segue之前

更改为自定义segue后

将此保存到Main.storyboard

Answer 1

尝试检查您是否在故事板上设置了类似的选项
这个指标是在推送的视图控制器上推断出来的（但我很确定它不算数）。

和/或强制导航栏和底栏使用，在推送的视图控制器的-viewWillAppear内以编程方式显示

[self.navigationController setNavigationBarHidden:NO animated:NO];
[self.navigationController setToolbarHidden:NO animated:NO];

Answer 2

更改segue时，导航栏和工具栏应在故事板中消失 - 这是正常的。您可以将底栏的模拟指标更改为“半透明工具栏”，它会将其添加回来，因此您可以向其添加按钮（您只想更改模拟指标，而不是拖动另一个工具栏，这将添加第二个工具栏）。在运行时，您仍然应该看到两个条形按钮。

Answer 3

(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    ViewController * controller = [[ViewController alloc]init];
    controller.hidesBottomBarWhenPushed=YES;
    if ([segue.identifier isEqualToString:@"Commentsegue"]) {
        //For hiding the tab bar 
        [segue.destinationViewController setHidesBottomBarWhenPushed:YES];
    } 
}
