I'm creating an UIViewController in IB. And I want to use this controller with a UINaviagationController.
The problem is when I use this view controller with the navigation one the title bar appears and all the elements on view go down. Ho can I take account of this when creating the controller in IB ?
PS: Now, I just put everything a bit higher. But I don't think it's a right way.
In IB select the view controller view, open the inspector, select the View Attributes tab, and on Top Bar specify "Navigation Bar". This will make a Navigation Bar in the view and then you'll be able to place your subviews in the remaining content.
In the same way you can inform IB if your view will contain the status bar, the tab bar, a prompt.

I have the first storyboard has UINavigationController its continues to the second storyboard but it doesn't appear there only when running the app.
I link between storyboard by (Storyboard Reference)
The first storyboard
The second storyboard
The UINavigationController doesn't appear in the second storyboard its appear only when running the app.
according to navigation controllers property it will not show the navigation bar in your case , if you want to edit or customise navigation items or navigationbar then you have to make changes programatically .
but to make changes in navigationbar or navigation items there is some limitations sometimes you can't fully customise it and sometimes you customise it depend on your requirement ... :(
I suggest you that use navigation property but hide the navigation bar
and on place of navigation bar (on top of every view controller) set a
view which will look like navigation bar and you can easily customise
it as per your requirement .
This is normal behaviour of the Storyboard as the controller in your second storyboard does not know if it is a controller in a navigation controller, hence it does not show the navigation bar. If yo want to show the navigation bar in the storyboard you can select it in the Simulated Metrics in the Attributes Inspector (shown here in that thread). You can see it working by giving the controller a title for example.
I have a viewcontroller and a tab bar controller. I want to change view controller as initial view controller and create a segue to show tab bar controller.
I have tried to set the new initial view controller. There are 2 ways. First, check the tick box "Is Initial View Controller". Second, drag the arrow to new screen. It does not show any error, but it shows the tab bar controller as usual and I can't find the view controller either.
Anyone know how to what is going on. Please tell me to fix. Thanks
You need to use a UINavigationViewController and connect it up in the hierarchy in a similar fashion to:
The leftmost view is the "view" that you mention, which needs to show the UITabViewController.
I've added a button for ease of use.
The next along (send from the left) is the UINavigationViewController. No settings on here need to be set etc... it's pretty much "plug and play" as to put it.
The next view (third from the left) is the UITabViewController (with corresponding views to it's immediate right).
The connection between the UINavigationViewController and the UITabViewController is "rootViewController" as the Tab View is the "root view controller" e.g. the primary view controller.
The segue between the first view, and the navigation view controller is merely a "show" segue. I liked directly between the button and the navigation controller in Xcode.
Hope this mash-up helps!
Edit I wrote a quick mask up of what I posted in the images for you to play with: https://dl.dropboxusercontent.com/u/61211034/Stackoverflow/NavgationViewController.zip
Based on your storyboard's image, looks like you don't have any NavigationController embedded to your root LoginViewController, try this:
Select your LoginViewController on your storyboard
Then in xcode Menu bar at the top, go to Editor -> Embed in -> Navigation Controller (as you can see in the image below)
Then your NavigationController will be set as your Initial View Controller, and see your LoginViewController be displayed and work as expected your segue.
I'm trying to add a view that is a form that has 3 elements. These elements will be inside of a static grouped table. I need a navigation bar at the top with a "Save" and "Cancel" button. Both buttons should send the user back to their previous screen when tapped.
Within the storyboard, I have tried creating a Navigation Controller and then adding a table to it, but I get the error of "Static table view are only valid when embedded in UITableViewController".
So, I tried creating a Table View Controller, but the storyboard won't let me put a navigation bar into one of those for some reason...
What is the best way to go about doing this?
Add UITableViewController to your storyboard and then choose Editor > Embed in > Navigation Bar Controller from the menu. This will wrap your table view controller in a nav bar controller and you can then add your Save and Cancel buttons to the navigation bar.
It might seem a bit wasteful to create a navigation controller with only a single sub-controller just to get a navigation bar but it's the accepted way of doing it.
Oh... this iOS stuff is hurting my head.
I wanted to do the same thing, have a TableView, with a Navigation Bar at the top, but there was no "Embed in.. Navigation Bar" menu item, just "Embed in.. Navigation Controller".
Eventually, solving this was easier than I thought.
I just needed to add a Table View Controller to my storyboard, then CTRL+drag a Segue from the "calling" view controller to my new Table View Controller, and, voila, it gives me the Navigation Bar straightaway.
I have implemented the search bar for the table in the first tab and this works fine and filters fine, however, with the same code and the xib linked up all the same etc on the second tab it no longer displays the search bar. Is there a simple reason to this?
Separate out the UISearchBar into its own class and then call it from the multiple views. It is not meant to be reinstantiated for each view controller.
Yes, there is a simple reason—the search bar is a subview of your main view, so when that view gets swiped off screen, it disappears with that view. To fix this, you'll have to add the search bar to the view that holds your tab bar controller—you'll probably have to put it in MainWindow.xib. You can still connect it to your tab bar controller if you need to—just add a reference to in the XIB.
How exactly does one go about implementing a custom toolbar for the main table view section of a split view?
The program I am writing for the iPad is landscape only so the split view has a static table view along the left side, and at the top is the toolbar with a title. It is this toolbar I would like to change. I have created the split view controller, table view controller, and detail view controllers programmatically so I should have reference to the toolbar object. The only thing is I don't know how to reference it so I can overwrite it with my custom toolbar.
Is it the split view controller that creates this toolbar? Or the table view?
Any ideas?
It's a navigation bar, not a toolbar. You'll want to investigate the navigationItem property of the UIViewController responsible for the view with the navigation bar. This is an instance of UINavigationItem; see the documentation here: UINavigationItem.
