Q:

Nav Bar disappearing on popviewcontroller

On one of my views, when a button is pressed I call another view that is a SplitViewController.   If this SplitViewController is called via one of these buttons I have special objects to add to the view.   mostly just nav bar items, like a cancel button.   This view can be accessed elsewhere and these items are not needed which is why there is the special condition. 
However, when the user is done and i pop the ViewController back to the previous screen that was selected, the nav bar disappears on that screen.   I am not setting it to hidden nor am I doing anything strange with the nav bar.   Simply adding the SplitViewController then popping back. 
Some code..
//declare the split screen VC
SplitScreenViewController *split = [[SplitScreenViewController alloc] init];

//set the flag that this VC is coming from a button, so we need the extra nav bar items
[split setIsFromButton:YES];
[self.navigationController pushViewController:split animated:YES];

now the call back is simply...
- (void)cancelSelectionBtnClicked
{
     [self.navigationController popViewControllerAnimated:YES];
}

and when the view returns, the nav bar is gone. 
any ideas? 
edit it should be noted this exact same thing is done elsewhere the same way(as far as I can tell) and the nav bar is visible on return. 

A:

In your ViewController's viewWillAppear you can again make your navigationBar visible. 
- (void)viewWillAppear:(BOOL)animated
{
    [self.navigationController setNavigationBarHidden:NO];
}
