I have been implementing a UIPageViewController and would like to add a toolbar to the bottom of my UIPageViewController that contains 3 buttons. Sadly, I can't figure out how to do this as I can only put the toolbar on one of the UIViewControllerand when I transition to another view controller the toolbar is no longer there. Is it possible to create a toolbar that spans all UIViewController's that are embedded in the UIPageViewController?
Thanks in advance.
edit: I have already implemented my UIPageViewController and have added two UIViewControllers inside the UIPageViewController. Is it still possible? Maybe it is possible to embed my already created UIPageViewController in a UIVIewController?
Create UIViewController and add UIPageViewController in that. Add that toolbar on UIViewController. after adding UIPageviewcontroller bring subview to front that toolbar.
So your view hierarchy will be UIViewController > UIPageviewcontroller > Toolbar.
As your toolbar is added on UIViewController it will be shown above all pageviewcontroller's viewcontroller.

I have 6 UIViewControllers in my app at the moment, and while they are all different, they should all share the same custom toolbar at the top, as well as a drawer which is opened/closed by a button on said toolbar. The "toolbar" and "drawer" are both UIViews with some stuff inside. Is it possible to use the same UIView objects for all 6 of my UIViewControllers? Or do I have to copy the constraints, segues, controller code, etc for the toolbar and drawer for each UIViewController that I have in my app?
Take a look at containerView.
You can add containerViews in each of your ViewControllers and embed your UIView.
What you could do in this situation is make a view controller that embeds a child view controller. On this view controller, you would set up your toolbar and drawer, then you would have a Container View that can embed a navigation controller which would manage all your other view controllers. On a storyboard, you can right-click and drag from a Container View to another controller to embed it.
As my screen have static options, so I created a screen with static cells from UITableViewController class instead of UIViewController
Now When I'm trying to add the Navigation bar from storyboard it never adds above UITableView. Always added at the footer of the table view.
Can we add without programmatically?
Please refer screenshot:
Appreciate your help!
Thanks
In Storyboard, you can't add any other view at the same level of the TableView in TableViewController, so adding UINavigationBar won't work here.
You can show navigation bar using UINavigationController:
In Storyboard first, select your Table View Controller.
Then Open Editor menu, and select Embed In option, and choose Navigation Controller. You will get your navigation controller pointing to your tableview controller.
To solve your problem, you can embed your UiTableViewController in a UINavigationController from storyboard.
Just add a UINavigationController on the storyboard and drag to your UITableviewController and set it as either root or push.
You dont have to manually add the UINavigationBar.
Hope this helps.
A simple way is that you can embed your UITableViewController in a UINavigationController:
Select your UITableViewController in the Storyboard.
go to Editor => Embed In => Navigation Controller
The second solution is to add it programmatically, as you just said.
Lets say we have a UIViewController embedded in a UINavigationController, the UIViewController segue to another UIViewController.
The second UIViewController has the standard left navigation button that "unwinds" to the previous UIViewController.
I don't seem to be able to add a righthand button (using a UIBarButtonItem) to the navigation bar of the second UIViewController via the Storyboard, when I attempt this the button ends up creating a tab bar at the bottom of the UIViewController (see below, notice also the left buttons are missing). Is there some trick I am missing?
I could embedded the second UIViewController in its own UINavigationController but then I loss the back button functionality.
I know it is possible to add the button in code so all is not lost if I am attempting something that isint possible.
To do this in the Storyboard, you need to place a UINavigationItem onto your UIViewController. Then you can add your UIBarButtonItem(s).
I have some static cells that I want to display, so I have a UITableViewController. There is also a NavigationBar in this scene that contains some buttons at the top. The setup looks like this:
If I had a UIViewController that contained a UITableView in it, the setup would look like:
So, the question is:
Why does the Navigation Bar have to be embedded inside the UITableView when using a UITableViewController? (I have tried putting it elsewhere but IB won't let me)
I know that UITableView is a subclass of UIView, but is it OK that the top level element in the hierarchy is not a View (but a TableView)?
Thanks.
You shouldn't be placing your UINavigationBar in your UITableView. You should be putting your UITableViewController in a UINavigationController, because that will provide a UINavigationBar for you.
So if you select your UITableViewController in the storyboard, you can choose Embed In -> Navigation Controller from the Editor menu. This would be the proper way to do it.
There are two ways to use a UINavigationBar in iOS:
Embedded inside a UINavigationController (recommended)
As a standalone object
For your particular situation, I'd recommend that you put your UITableViewController as the rootViewController of a UINavigationController. That way you automatically get a navigation bar which you can customize according to your needs. In a typical user experience, when you tap some of your table view rows a new view controller will be pushed onto the navigation stack, so you'll probably end up needing a navigation controller anyway.
What if you decide to use a navigation bar as a standalone object? This is perfectly fine, you can use it inside a view hierarchy as an ordinary UIView, but you'll need to create another object that implements the UINavigationBarDelegate protocol and set it as the delegate property of your navigation bar. If you use a UINavigationController the delegate is already set and configured for you. You also need to add/remove navigation items (instances of UINavigationItem) to your navigation bar by using the pushNavigationItem:animated: and popNavigationItemAnimated: methods.
And about your question on the view hierarchy, you can use a UITableView anywhere a UIView is required. The only caveat is that a UITableView is a view hierarchy on its own and that may restrict your layout a little bit.
The way a UITableViewController works, is its root view is a UITableView. So there is no way to put the UINavigationBar anywhere other than in the UITableView.
I tend never to use a UITableViewController as it doesn't really give you much.
If you particularly want to use the UITableViewController, I don't believe that there is any real problem in having the navigation bar within the table view. You just need to make sure that you set the contentInset on the table view such that the navigation bar doesn't block the content. Though it seems a bit backward to do it this way.
My recommendation would be to just use a normal UIViewController with a navigation bar and a table view.
If you actually need functional navigation, you need to put your UITableViewController within a UINavigationController.
Hope this helps :)
Let me know if anything is still unclear.
I'm new to iOS development, I just have UITableViewController in a storyboard. I would like to add a top bar to it with some buttons, how to do that?
Notice, I'm using UITabBar that is created by "Storyboard" and my ITableViewController is one item of the UITabBar.
When you create the UITableViewController, do the following:
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:tableViewController];
and then instead of setting the table view controller as the view, set it to the navigation controller. Inside your table view controller, you can set the left and right buttons for the navigation bar to UIBarButtonItems (ask me if you want to know how to do that).
Select your UITableViewController and go Editor > Embed In and choose a navigation controller.
You might look at using the UINavigationController.
https://developer.apple.com/library/ios/DOCUMENTATION/UIKit/Reference/UINavigationController_Class/Reference/Reference.html
If you do not want to use UINavigationController, then what you could do is create a view that has the "top bar" that you are looking for, then add the UITableViewController's view to your new UIView.
You need to create an UIViewController, not a UITableViewController, and then place the elements you desire however you want (in this case, a Table View and a UIToolbar).
