Question

I recently started using interface builder, the problem i’m facing right now is when i use the back button of navigation controller, my UI elements’ y axis go up by roughly 20-30 px, is there some setting i’ve to use to avoid this problem ? And they go up only when i use pushViewController, when i use popViewController it loads the way i need.

Code i’m using for pushing:

    examVC=[[ExampleClass alloc] initWithNibName:@"ExampleClass" bundle:nil];
    [[self navigationController] pushViewController:examVC animated:YES];

I’m attaching the images with the question. Please note how label has gone down about 20-30 px.

Why does this happen? What am i doing wrong ?

Thanks for all the help.

Edit : changed the screens for better clarity

I’m using pushing code on the round rect button.

Screen 1:UI elements set in my IB

Screen 2: How it looks when pushed from previous view

Screen 3: How it looks when popped from the “Next View”

Answer 1

My home view controller had the navigation bar hidden, the screen i posted was the second view which comes after the home view. I wanted to hide navigation bar in the first view only, so i had used :

- (void)viewDidDisappear:(BOOL)animated
{
     [self.navigationController setNavigationBarHidden:NO animated:animated];
     [super viewDidDisappear:animated];
}

It caused the problem because i was showing the navigation bar again in viewDidDisappear, so the view would load first then the navigation bar would be shown causing it to overlap.

So i put the same code in viewWillDisappear, which removed the issue. As navigation bar did load before loading of the next view. Now the view loads just like i designed it in interface builder.
