This is what I wish to do.
---- Segue : show ---->
on the destination page, I want to hide the tab bar from the previous page and show the toolbar instead.
When I check "Hide bottom bar on push" on storyboard, the tool bar on the destination page disappears as well.
I think you should change the title of your question since you want to replace the tabBar with a toolBar and keep the navigationBar. At leas this is what I understand from your sketch.
As for the question, have you tried hiding the tabBar in viewWillDisappear in your first view?

if I press the third tab bar (tab bar index : 2), and it opens RequestVC, it will show a black screen like the picture below, so I can't see my label. and I don't know why the green icon in the bottom dissapears
I don't understand why this happens. I just uncheck "transculent" in the navigation bar, and in the NewRequestVC I also check "Hide Bottom bar on Push"
I recreate your storyboard, it's working fine for me.
Try these steps:
delete your navigation controller
embed your request VC in navigation controller
connect your main tab bar to navigation controller relationship segue as view controllers.
Try you restart Xcode?
If there is nothing wrong in storyboard then probably in your code.
The incorrect navigation bar is appearing on my Table View Controller screen (see Storyboard Below).
I would like what's displayed on the storyboard to be my navigation bar (i.e. with "Main Feed" title and Sign Out button on the top right). However, this is what I'm actually getting -
There are two issues here: 1) The incorrect navigation bar is displaying (this one has a login back button); 2) the first few table view cells are placed underneath the nav bar vs. under it.
This happened after I embedded the Table View controller in the Tab Bar Controller. I want a bottom tab bar in the main portion of my application hence the reason why I added the Tab Bar Controller. Any suggestions on how to fix this? Rather than using the Tab Bar Controller in storyboard, is there a way to do this programatically? Thanks!
The navigation bar that you are seeing on top of the stack is the navigation bar from the UITabBarController itself, that is why you are seeing the back button show "login". There's a few ways to work around this, programmatically:
When you initialize the UITabBarController, set it's navigationController's navigation bar property to "hidden"
Go through each view controller form the beginning of your app up to where you first see this problem and in the "init" method of the viewController you are testing, set the navigationbar to hidden. Something like, self.navigationController?.navigationBar.hidden = true;
This is how you can "debug" this issue, but it's going to take some tweaking to get it right.
I have a problem with the tab bar controller. On one of the views that is linked from the tab bar controller (view1), there is a custom segue that leads to another view (view2).
Help me to unhide the tab bar which get hidden due to the custom segue.
The navigation bar and the tool bar should disappear in the storyboard when you change the segue -- that's normal. You can change the simulated metrics for the bottom bar to "Translucent Toolbar", which will add it back, so you can add buttons to it (you only want to change the simulated metrics, not drag in another tool bar which would add a second tool bar). You should still see both bars with their buttons at run time.

I want to add a bar button item on the navigation bar. (Say View 1 here.) The view that will segue to View 1 is embedded in a navigation controller.
However, the navigation bar is not showing in this view.
If I use attribute inspector to add a opaque/ translucent navigation bar, there will be a navigation bar in View 1. But if I drag in a bar button item, it cannot be shown in the storyboard. Though the bar button is in the document outline, it cannot be shown on the storyboard. Also, if I run the application, it is not on the screen.
When running the application in the simulator, View 1 will have a navigation bar on the top of it, since I use "Show" rather than "Show Details" to show View 1. I tried to embed View 1 in a navigation controller again, but it won't help much.
Can anyone tell me how to add a bar button in this situation using storyboard? And why the navigation bar is missing from the storyboard?
Thanks in advance.
I figure it out by myself.
Drag a Navigation Item from the object list, and then add bar button item to it.
Thanks to rdelmar for his idea, though drag out a navigation bar won't work in the way I thought it should work.
In my situation, View 1 is a table view. Drag a navigation bar to the view will cause it to be the header view for the table, rather than a navigation bar I had expected. Then there will be two navigation bar in the view when I run the application.
Of course we can drag out a navigation bar and add a button to it, it might work different with your expectation. As I had said, it might leads to a view which contains two navigation bars.
You can fix this by drag out the Navigation Item (contains the bar button you had added) inside the Navigation Bar out. In my situation, I drag it out and put it the same level with the table view inside the document outline. Then it won't become the header view for the table view.
After that, we can just delete the navigation bar from the document outline.
I have no idea why the navigation bar disappears in my storyboard. If anyone has some idea for this, please let me know.
It sounds like you're adding the navigation bar by using the Simulated Metrics. If so, this doesn't add one at run time, it's only for layout purposes in IB. You should drag out a navigation bar from the objects list, and add your button to it.
In my app i'v UITabbarController as rootviewController with 3 tabs on it, each tab has its own UINavigationController.On the first tab i'v attached a UIViewController that hides tab bar and navigation bar, by click on a button user can go to next screen that will show tab bar as well as navigation bar.Now the problem is when i click on first tab on this view controller (which is already selected by default) it takes me on previous view controller and i want it should stay on the same screen.How to achieve this?
Edit: I dont want to disable bar item at index 0 as this turns it into UIControlStateDisabled which make it different looks from others.
Is there any way to set image for UIControlStateDisabled for tab bar item?
Any help or suggestion would be appreciated.
Try this may be helpfull...
[[[[self.tabBarController tabBar]items]objectAtIndex:1]setEnabled:FALSE];
set "objectAtIndex" that you want..
