uinavigationbar

I'd like to add a right bar button with the system's info icon to a navigation bar. But I see that UIBarButtonSystemItem does not provide such type of button. On the other hand, so I tried with a UIButton of type UIButtonType.infoLight , but I am not allowed to assign it to navigationItem.rightBarButtonItems .

I have a table view that pushes to a detail view controller. From the detail view controller, when I press the 'back' button, I'd like an integer value to change. How do I edit the navigation bar back button's action programatically.

When I do that, the height of the nav bar increases, and my background image no longer fills that nav bar vertically, so it looks very bad. How can I account

I've an issue with a search bar in a navigation bar using the property displaysSearchBarInNavigationBar = YES . I have an empty space between the navigation bar and the search content which is equals to the height of the navigation item + status bar. It's just as if during building the view, the framework doesn't know that my search bar is the navigation bar... This empty space appears before tipping anything, and when displaying the result tables. I haven't found anything related to this issue except this topic: Empty UISearchbar space when combining search bar with Nav bar in iOS7? I tried

I have created an application which needs to have a bar above the navigation bar and other views. To accomplish this, I am using a view controller with a view for the top bar, and then a container view for everything else. Sometimes, the top bar needs to be hidden. I'm using autolayout to hide the top bar (set its height to 0), and the container view expands to fill the screen (container top equal to the top bar bottom). The container view contains a navigation controller because I need a navigation bar below the top bar sometimes. When I start the app, this all works fine as shown below: As
