I have a simple linear chain of UIViewControllers.
The first one has a show segue to a NavigationViewController, then it goes on the same way with all the others.
When I switch from wCompact-hRegular to wRegular-hCompact to fix the landscape layouts the first viewcontroller doesn't allow me to do anything. The tree diagram at the left side of the storyboard screen shows the views but they are not written in black. They are transparent. Even if I select them and put the coordinates or dimensions nothing happens. There are only a button and a label. Others Controllers are all ok, they can be fixed. What is happening to the first one?
With XCode 6 you can add views, that are only visible in the selected size class (f.e. Compact + Compact). When you change to a different size class the views are disabled. To fix this navigate to the attributes inspector and select installed for any class sizes.

In my project I want the iPhone portrait version to stretch a view but the landscape and iPad version to have a specific width so it doesn't stretch since the iPad is wide and so is iPhone in landscape. The problem is, when I set one up, I switch to the other one and everything has disappeared. If I start dragging views from the left panel to the storyboard they appear again, but when I switch to the previous size class everything has disappeared on that one. I also can almost never drag on that ViewController's box to do what I want. For example, if I want to drag from a UIButton to the background of the layout it would normally bring up a menu with 'vertical spacing' etc but now it comes up with 'Outlets Delegate'.
How do I fix these issues? Nothing is working.
Solved it by deleting everything in the ViewController, re-adding everything in w-Any h-Any and adding specific constraints in the relevant size classes.
in my universal app I have an UITableViewController embedded in a UINavigationController. When I add a UIView to the top of the tableView and insert a UILabel which is centered in the container, the label is only visible on iPhone but not on iPad.
I tried creating a new testapp, only consisting of these two controllers, the view and the label. It works on both, iPhone and iPad. So I added two new controllers to my app in the same way and made the navigation controller the initial view controller. Label is visible on iPhone but not on iPad.
For me it seems, that I have changed some global settings in the app; on another view I have similar problems with stackViews, but I first concentrate on this "simple" problem...
Any ideas what might be wrong in my app-settings?
tableViewController embedded in navigationController
Take a UIViewController embedded in a UINavigationController. Add View, Label, and TableView and check it
Ok. Now I know what was the problem. Never have checked, what's going on with those size classes.
During development I changed from any/any to a smaller size, not knowing, that this is not only taking effect on the layout in the storyboard. Everything I added after changing did'nt show on iPad.
Solution: Select storyboard, in "File Inspector", uncheck "Use Size Classes"
I have a custom view which needs to be displayed on all the iPhone devices(4, 4S, 5, 5S, 6 and 6 Plus). When creating the custom view XIB, I have mentioned it as "Inferred" but it is not resizing for iPhone 6 and iPhone 6 Plus devices. I am not able to figure out the issue. I am confused on what would be actual differences between "Inferred" and "Freeform". Can someone please explain the differences?
Inferred resizes the scene according to its parent scene. For example if you have a scene that is the size of an iPad and then you add a new scene to your storyboard and create a segue to it, it will automatically resize to the same size as the iPad scene (where the segue originates from).
Freeform ignores the above rule and you're able to size it as you see fit, in the utility pane on the right.
Both of these however have nothing to do with how the view is displayed and sized on actual devices. For that you need to use auto layout and constraints. Or springs and struts. Some even do it in code if they need more flexibility.
“Inferred” is the default setting for storyboards and it means the scene will show a navigation bar when it’s inside of a navigation controller, a tab bar when it’s inside of a tab bar controller, and so on. You could override these settings if you wanted to, but keep in mind they are here only to help you design your screens. The Simulated Metrics aren’t used during runtime, they’re just a visual design aid that shows what your screen will end up looking like.
"FreeForm" Usually you use the freeform property when you add the view controller as a child to another view controller programmatically and you really want to have that fixed size.If you push the view controller or you present it as modal view controller (and you use the modal presentation styles) then there is no need to use freeform.Also another use of the freeform property is to preview the actual size of your view controller when is presented as a modal view controller using existent presentation styles.
I am attempting to create a custom popover for an iPad application in landscape orientation. I created a new UITableViewController with static cells on my storyboard and set the size setting to "free form". I then set the size of the UITableView to my desired size. I connected a Modal segue from the parent controller to the new popover.
Then in the parent UIViewController I created a method that performs the segue through a custom presenter. After working through a bug in Apple's orientation handling routines, I got the popover to show at the correct location.
When I run the app, I then discovered that in the top right hand corner of the UITableView a white box is displayed that covers whatever I place in the UITableViewCell. The more cells I place in the table the longer this white box appears. So I believe it has something to do with the UITableViewCell not orienting properly although I have not figured out what yet.
I cannot seem to find what this box is, nor have I had any luck getting rid of it. Has anyone seen something like this? Any help to get this white box remove (or whatever is needed to get the cells working correctly again), will be greatly appreciated.
Thanks in advance
For anyone who is interested, I was able to work around this problem. It turns out that there is a bug in the modal segue logic that does not handle landscape orientation. So I created a XIB and presented that as my modal view. I still need to adjust things since it is landscape but the view displays correctly.
From what I understand this storyboard bug should be fixed soon.
In my iPad app, the view controller include three button, one navigation bar and one tool bar.
When i rotate my view controller from portrait to landscape mode, three buttons are disorder.
The navigation bar also collapse to tool bar.
How can i do it?
You need to learn about layout. You can lay out subviews of your view in three ways:
Manually
Autoresizing (springs and struts)
Autolayout (constraints)
If this is a new project in Xcode 4.5 or later, you are using autolayout by default. So you need to go back into the nib and edit the constraints that Xcode already gave you, because obviously they are not what you want.
You might want to read the Layout section of my book, which has extensive discussion of how autolayout works and how to edit constraints in the nib: http://www.apeth.com/iOSBook/ch14.html#_layout
Ideally you should keep your content under one xib per view controller, linking your buttons and nav bars by pinning to your layout should rotate properly; however there is one other option for a viewing a different xib when the device is rotated, see the answer below.
Easiest way to support multiple orientations? How do I load a custom NIB when the application is in Landscape?
