When my personal hotspot is active, my Navigation Controller becomes broken like attached image. I tried full screen presentation on my NavigationController in storyboard; But it doesn't work.
curropted one
correct one
You can't hide blue bar Navigation. It's there to make sure you know that something is connected to the hotspot.
personal-hotspot is on , statusBar's height is 40
personal-hotspot is off , statusBar's height is 20

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
In my app, I have some webviews. A transparent status bar doesn't look good for full screen webview. I want to make the status bar TRANSLUCENT, just like the game center.
I notice that the status bar would be drawn translucent if there is a navigation bar under it. But I want a translucent status bar BY ITSELF.
Is there any way to do this?
If you look at the Human Interface Guidelines section about the Status Bar it recommends (emphasis mine on the section most related to your question):
Prevent scrolling content from showing through the status bar. As
users scroll, you don’t want them to see a confusing mix of app
content and status bar items in the status bar area. To give users the
impression of spaciousness while still ensuring maximum readability,
make sure the status bar has a background that obscures the content
behind it. Here are a few ways to keep scrolling content from showing
through the status bar:
Use a navigation controller to display content. A navigation controller automatically displays a status bar background and it ensures that its content views don’t appear behind the status bar. (To learn more about navigation controllers, see “Navigation
Controllers”.)
Create a nondistracting custom image—such as a gradient—and display it behind the status bar. To ensure that the image stays behind the status bar, you could use a view controller to keep the image above a scrolling view or you could use a scrolling view to keep it pinned to the top.
Position content to avoid the status bar area (that is, the area defined by the app’s statusBarFrame property). If you do this, you should use the window’s background color to provide a solid color behind the status bar.
As the status bar is totally transparent and any content can go on top of it, I just create an empty UIToolbar that is 20px height which just looks like a perfect translucent background for the status bar.
This is not an ultimate solution, but it really helps and it is very easy to implement when you don't need a real tool bar.
Thanks to Apple that they do not provide an option to set the status bar from transparent to translucent.
In Xcode 6, create top, bottom, left, right constrains and set the
- constants to 0
- priorities to 749.
- Don't forget to UNCHECK the "Constrain to margins" check box.
How to create constrains?
At the bottom right of your storyboard window, there's four buttons. The second from your left has the constrains. Please google about constrains in Xcode 6 since it's a kinda new feature.
Hope this help,
Bit of a strange one.
I have a UIButton which works when located anywhere on the view except the top left hand corner when in landscape mode.
I have a navigation bar with a back button nested in the same area but when the the video enters full screen and playback state changes this navigation bar is hidden.
any ideas?
As thought, the problem was occuring due to the hidden navigation bar and the navigation item located in the same place.
The only solution i can find was to remove the navigation bar from superview then add it back when needed.
Your view's hierarchy is not properly configured. To properly configure your hierarchy, you need to navigate to either the xib or storyboard that you're working with, and re-order the button so that it's on top of anything that falls within it's similar bounds. A common example is that you added a UIView, which is clear, and you had the button underneath it, and now you can't interact with it even though you can't see it.
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.
I have a UITabBarController displaying a number of settings-screens in my app. I want them to be shown on just a part of the screen for layout reasons. In fullscreen, the lists become unreadable (too wide), there are just a few controls per page making the page feel very empty, and the tabbar buttons are far away from the content (Fitts law).
Using presentModalViewController with the UIModalPresentationFormSheet style gives me the size I want. I do this on top of an empty background, since in my case it doesn't make sense to display anything behind it. The "real" working area is displayed with another presentModalViewController in fullscreen mode on top of it all.
This works but feels like a hack. One problem is, I can't make the background behind the settings dialog move in the transition to fullscreen with the UIModalTransitionStyleFlipHorizontal style.
TL;DR
Can I embed a UITabBarController non-fullscreen in another "background"-view? I can't find any information of how I would do this.

Why don't you try it out?
Create a container view of the size you want the tab bar controller to have.
Create the tab bar controller.
[containerView addSubview:tabBarController.view];
