I have a project, which have relationship segue as photo below.Everything work fine. But When I rotate the device/ iOS simulator The Navigation Bar is disappeared. What happen ? Some setting I need to know ?

Check the Navigation Controller properties in the interface builder, and make sure that Hide Bar When Vertically Compact is unchecked

How can a navigation bar be supported in both iOS 6 and iOS 7 with a UIContainerView via a storyboard?
I am updating an iOS 6 app to iOS 7, but want to continue to support iOS 6. I have a main top level view that is embedded within a UINavigationController. The view within the navigation controller has a container view in it. I am using a storyboard to lay out the view.
On iOS 7 the navigation controller uses the entire screen, and I've set it up to put the container view content below the navigation bar. In iOS 6 the content of the view does not go under the navigation bar, so I have a blank gap below the nav bar.
Normally I would just reset the origin of the offending view on iOS6 (in ViewDidLoad or somesuch) and go on my way. However since my content is in a UIContainerView, I can't seem to change the frame after it loads. (I have tried this in prepareForSegue: when loading the UIContainerView. I'm open to having done this wrong? heh)
The closest I have found is using the following code under iOS 7 to make the nav bar opaque and keep the content out from under it, then using the entire space for my UIContainerView.
// tell the view to not extend below this nav bar
if ([self respondsToSelector:#selector(edgesForExtendedLayout)])
self.edgesForExtendedLayout = UIRectEdgeNone;
This solution works but has the side effect of showing the status bar as black (since it's more or less "blank" under the status bar). Alternatively, if I put the top edge of the container view below the status bar, on iOS 6 I have a big gap below the navigation bar.
I can eliminate the use of a navigation controller, but that seems a bit heavy handed in this situation and I'd like to use that as a last resort.
I've found the solution to this.
You need to set the barTintColor in iOS 7, which also seems to color the main status bar, as well as setting the nav bar to not be transparent like this:
mainController.navigationBar.barTintColor = [SRPRTabletHelpers customUserColor];
mainController.navigationBar.translucent = NO;
The non-transparency was the key, while setting the color sets not only the regular nav bar, but the color beneath the status bar as well.
I also needed to change my containerView top edge to be the full height of my view contained within the navigation controller, now that it is not transparent, and it works the same on both iOS6 and iOS 7.
While you mention to have already solved this, your method seems to require a lot of manual code and if checks. The iOS 7 UI Transition guide, in the Supporting iOS 6 chapter mentions another way: first design your interface for iOS7 as you have done, with your view extending below the navigation bar.
Then, in the interface builder open the size inspector for UI elements and modify the iOS 6/7 deltas. These values are applied when the storyboard is not run on iOS 7. For example, in your case you can select all your visual elements, then set the Y delta to -44, which is the standard navigation height. That will make the UI go up on iOS6, compensating the fact that the view doesn't go under the navigation bar.
I am trying to update my iPhone app to iOS7.
I am having major issues with the navigation bar. I would like it to have the new navigation bar.
As you can see from my image it has squashed the title to the top near the status bar.
I dont want to remove the status bar.
Surely it cant be that difficult to change.
I also noticed on some apps its changed automatically and on other apps it hasn't?
Did you try to add:
self.edgesForExtendedLayout = UIRectEdgeNone;
in the viewDidLoad method?
You should try and do it the correct way by adding your view controller to a UINavigationController and use its UINavigationBar. This will handle most layout issues for you and will also be backwards compatible. If you post the code where you bring your ViewController on screen, we will gladly help to wrap it in a navigation controller.
When I use a modal view controller in iOS7 it slides underneath the status bar. Is there a way to stop that from happening without having to adjust the view based on what os it's running on? You can see that the Close button is pushed up underneath the Carrier text on the status bar. Is there any way to get the modal view controller to recognize my status bar?
Have you seen this? UINavigationBar/Status Bar issue in IOS7
There are a couple of things you can try, but I think what you're looking for is here, in the iOS7 Transition Guide: https://developer.apple.com/library/ios/documentation/userexperience/conceptual/TransitionGuide/AppearanceCustomization.html
Been trying to figure out why this happens for a few days.
My app is supposed to have a shared view between all screens that handles navigation. So I made a nib for the navigation with a few buttons on it and added that view to the window (which I'm told is a bad choice)
This global view stores 4 navigation controllers so that users can swap between them without losing their place (much like how a tab bar works). But it looks as if adding the view to the window has affected the way my app resizes for the in-call status bar. In 5.0 the entire app works perfectly, but in 4.0 it's completely wrong.
On 4.0 if I enable the in-call bar on a screen it will not move at all.
If I push a view controller with the in-call bar the navigation bar appears at the top, but the view appears 20 pixels lower than it should
And if I have the in-call bar enabled, push a screen, then go back, the navigation bar moves down 20 pixels (as it should), but the view stays where it is and is clipped by the navigation bar.
What is happening on iOS 5 that isn't happening on iOS 4.x that makes these changes? the app is all buggy on 4.3.
Create a "dummy" view controller (UINavigationController works well). Then add your view to that. Without using a view controller hierarchy events will not be propagated correctly.
I suspect this works on iOS 5 because of the new "container" view controller system. They have moved the system to be more lenient in these areas. I can't give a more specific answer than that without seeing your entire app navigation design.
EDIT:
Also try using the wantsFullScreenLayout property. It may help.
Just like the Dropbox app for iPad I want to add Tabbar in the main view controller of splitview.. wondering what is the best way to achieve this?
Checkout the screen grab of ipad dropbox app... I am referring to the tabbar used on bottom left.
Select the Navigation Controller of your Split View Controller in Xcode and in the properties panel it will give you checkboxes to enable/disable top navigation bar and bottom toolbar for it (Dropbox app in your screenshot have both, so you should check both of them if you need the same layout).
