I started with a singleview app. I then embedded a navigationcontroller. At the bottom of the scene1, there is a bar. It isn't anything I put there. It doesn't show in the document outline but does obscure UI elements that I drag to the bottom of the view.
However, once I run the app, the bar is not visible. Anyone know what this bar is?
thats called bottom bar of navigation controller,
navigationController.toolbarHidden = YES;
or with animation
[navigationController setToolbarHidden:YES animated:YES];
In order to hide the bottom bar in the storyboard you have to select the view controller that contains that bar, go to "Attributes Inspector" > "Simulated metrics" and select "None" for the bottom bar.

I currently have an app with 2 view controllers inside a navigation controller.
They are pushed in this order:
A, B
A has an empty (but displayed) navigation bar and B has a navigation bar with:
1) A title view
2) A custom leftBarButtonItem.
This is the initialisation code:
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:self.addFavoriteButton]; // addFavorite is an IBOutlet to a view outside the view hierarchy of my VC.
When I go back from B to A, either by panning from the left or touching the back button, the right button is displayed in a weird position on the left of the screen during the transition.
The B layout is similarly used for a C view controller, without any issue.
You can see a screenshot from the botched transition:
As you can see, the heart (my right button) is wrongly displayed.
How can I fix this ?
Figured it out:
My button had a constraint, removing it fixed the issue.
The title explains it. I can't seem to figure out the specific way to put it while searching for a way to have a menu bar under a banner, then, have it move up to a fixed position on the top of the page as you scroll down (kind of like the salmon-colored box that is currently showing up to the right of this form).
I will be using a simple table for a menu bar.
Many Thanks!

I am trying to have a UINavigation controller with a title view the logo for the app, and a UISegmentedControl below it, however, it is too tall to fit in the Navigation bar. Is there any way to have a toolbar with a UISegmentedControl that is under the navigation bar and doesn't move when you switch views by selecting a Segment? Thanks!
I solved this by setting animated to NO when switching views and keeping the same UIsegmentedcontrol within a toolbar under the NavigationBar on all three of my views
I created left bar button item and array of 2 bar button items to the right bar button item. Here, the problem is, if I tap on area out of the left and right bar button items, the navigation occurs.How to remove this touch behaviour at the area out of the buttons?
I created left and right bar button items as shown in figure.Kindly answer my question.
Have you tried disabling the back button with the hidesBackButton property on the navigation item?
self.navigationItem.hidesBackButton = YES;
See the UINavigationItem docs.
How to hide the navigation bar of the center panel in JASidePanel and show custom bar and also have a custom button and then show the left panel of the controller??
The link is
https://github.com/gotosleep/JASidePanels
and also how to manage memory for the center panel?
You should try reading the header file JASidePanelController.h as it explains most of your questions.
To hide the navigation bar, on the centre panel do something like:
[sidePanelController.centerPanel.navigationController setNavigationBarHidden:YES animated:YES];
To customise the bar, try:
[[UINavigationBar appearance] setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
To show the custom button, subclass JASidePanelController and override:
+ (UIImage *)defaultImage;
Finally, to show the left panel, try:
[sidePanelController showLeftPanelAnimated:YES];
