Custom Push Segue removes navigation bar and tab bar in story board

问题

I have the following defined in a custom Segue, let us call it 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

In my story board I have just changed a standard Push segue to SegueX. For some reason this will remove my navigation bar and tab bar. Furthermore all UIBarButtonItems I have defined in the story board after the custom segue are hidden at runtime. How do I fix this? I hope it is not meant to be this way...

回答1:

The navigation bar and the tool bar should disappear in the storyboard when you change the segue -- that's normal. You can change the simulated metrics for the bottom bar to "Translucent Toolbar", which will add it back, so you can add buttons to it (you only want to change the simulated metrics, not drag in another tool bar which would add a second tool bar). You should still see both bars with their buttons at run time.

回答2:

Try to check if you have set on storyboard an option like

That metrics are inferred on the pushed view controller (but I'm pretty sure it doesn't count).

And/or force the navigation bar and bottom bar to be visible programmatically using, inside the -viewWillAppear of the pushed view controller

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

回答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];
    } 
}
