nested push animation can result in corrupted navigation bar multiple warning

I’m new in ios app developping and i’m having some trouble with multiple warnings.

I have a Navigation Controller that load a table view.
From that table view one touch on a cell pushes a new VC (basically, the detail of the cell).
And on that “detailView”, when a certain button is pushed, another VC is pushed.

  • When Video plays using AVPLayer, it stops background music ios
  • Run 32 bit library on iPhone 5s 64 bit
  • when using loadNibNamed why do we have to use 'first'? Don't we want to decouple different entities of our source code?
  • “Invalid Swift Support - The SwiftSupport folder is missing” with Xcode 7.3.1
  • How to debug slow app launch
  • Portrait mode only-iOS
  • I push the last VC with the following code :

    - (IBAction)toMoreDetail:(id)sender 
    {
        [self performSegueWithIdentifier:@"toMoreDetail" sender:self];
    }
    

    And when i do that, 2 warnings are poping :

    2012-08-05 02:25:41.842 appName[2145:f803] nested push animation can result in corrupted navigation bar
    2012-08-05 02:25:42.197 appName[2145:f803] Finishing up a navigation transition in an unexpected state. Navigation Bar subview tree might get corrupted.
    

    I didn’t find any good answer so far.
    Maybe anyone can help me with this problem.

    Thanks 🙂

    Edit : here is the code for the other segue :

    From the TableList to the VC of detail (the segue start from the prototype cell and goes to the detail vc) :

    - (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
    {
        if ([[segue identifier] isEqualToString:@"toDetailEvent"])
        {
            NSInteger selectedIndex = [[self.tableView indexPathForSelectedRow] row];
            DetailEvent* detailEvent = [segue destinationViewController];
            detailEvent.eventToDisplay = [listEvents objectAtIndex:selectedIndex];
        }
    }

    My guess would be your button is linked with the segue, so when you add an IBAction on it, you trigger the segue twice.

    If you go to your Storyboard and click on the segue, you should be able to see its origin and destination. Is its origin the entire view controller or just the button? You only need to manually performSegue if the origin is the entire view controller. Can you try comment out your [self performSegueWithIdentifier:@"toMoreDetail" sender:self]; stuff to see if it will work?

    It seem that if you use a storyboard and hook up your segue from the source vc to the destination vc and call the segue using didSelectRow you can not leave an else statement for a segue choice:
    This works:

    if ((indexPath.row == 0 && indexPath.section == 0)) {
        [self performSegueWithIdentifier:@"simpleLines" sender:self];
    }
    if ((indexPath.row == 0 && indexPath.section == 5)) {
        [self openAppStore];
    }
    if (indexPath.section == 4)  {
        [self performSegueWithIdentifier:@"pushSettingsVC" sender:self];
    }
    

    This does not work:

    if ((indexPath.row == 0 && indexPath.section == 0)) {
        [self performSegueWithIdentifier:@"simpleLines" sender:self];
    }
    if ((indexPath.row == 0 && indexPath.section == 5)) {
        [self openAppStore];
    }
    else  {
        [self performSegueWithIdentifier:@"pushSettingsVC" sender:self];
    }
    

    You get a weird double push when using navigation controller. I do this every time I start a project and always forget why it happens. Next time I
