I have a problem with a background image in a controller .
I set an image directly from a storyboard with ImageView , but this seems to be disproportionate and grainy on the storyboard , but then when you launch the app screen appears proportionate.
That makes me hard to graphic design because I see the storyboard no depreciation corresponding to reality
What can be ?
I hope I was clear enough
thanks
Go on your storyboard, select one of your view controller
Right panel > Size inspector > Select freeform in simulated size
Put the size you want
Note with autolayout you are designing "responsive" interface, that's why the screen is bigger because it's could be an interface which can fit both an iPad screen or Iphone, also a question of landscape/not-landscape.
I don't recommend to change this mode then, or only if you are building an app for a specific screen only.
Also, by default the layout is set to Any Width / Any Height that's correspond to all layouts possible but you can change this in the bottom of the middle panel.

Question: Can someone identify why I am getting the extra grey area shown in my add item (top screen in screenshot) and how to eliminate it?
I have tried manually setting the size of the background object, removing and re adding constraints, clicking all the Xcode generated solutions for handling the autolayout errors shown below, setting the presentation setting to full size ala this answer all to no avail; it refuses to be consistent with the main menu screen (bottom)
Context:
Running Xcode 11...I have two scenes in a generic barcoding app, the main menu and the add item scene, and I am designing with iPad's in mind. With the size class for ipad pro 9 (wR hR) and set to landscape orientation, my add item scene has a huge amount of gray area bordering the visible content, unlike the main scene (though there is also a little grey area in portrait)
Figured out what was causing my problem; was using the wrong form of segue between screens, per this answer, in my case, a modal segue when I should have just been doing a show segue. Deleting and adding show segues with the presentation set to Full Screen in the destination views Attributes inspector did the trick.
I have an OS X app originally built using Xcode 4, now using Xcode 7. When "springs-and-struts" was superseded by constraints, I reworked the UI to use constraints. Simple enough, and seemed to work well.
Fast forward two years after first release, and for the second release I needed to add controls and increase the height of the main app view. Unfortunately, my test team is using smaller screens and cannot see the whole view. They need to resize vertically.
Problem - even though the resize controls box is checked, the window cannot be resized. The controls do not show at run time. I tried
Setting lower minimum window content size height, but that did not change anything.
Changing content compression resistance did not change anything.
I am thinking this issue has something to do with constraints.... Any ideas on how to get resize to work?
Edit: After playing with a new test app some, I am more certain the problem is due to constraints. I have a control where I have constrained leading and trailing space to superview and width - there went horizontal resize.
I really need to have a view where the user can resize the window, but scroll the content. However, in this case, the content is other controls. I think on iOS, I would use a UIScrollView. On OS X, I have tried a scroll view control and have tried embedding in a scroll view, and neither have the desired effect.
I had the same issue and solved it by adding a view to be used as a "container" in the view controller.
Pin the top left corner of the "container view" to the view controller (leading space 0 and top space 0). Add equal width and height constraints on the "container view" to the view controller. Then move all your objects into the "container view" and add your object constraints on the "container view" not the view controller.
In my case, it happened in this way (Xcode 13.1).
I mistakenly added a view from IB outside of the window view hierarchy. The new view was added as a separated object (a top node in the interface builder file). I added the new view into the window by drag-n-drop.
I found the new view had different behaviours, for example, I couldn't set the top space constraint. With this view in the view hierarchy, I couldn't change the window size (content view size) at all.
I removed the view and added another in the view hierarchy, it worked as normal.
I think IB initialises the view differently if it is a separated object (top node of the interface builder file).
I'm converting an app that I made for iPhone to be used on iPad. Using constraints on the Xcode 6 storyboard is killing me right now.
With my rep score I can't post an image of what I'm getting, but basically even when I set the constraints and the placement of the object (a UIView) on a storyboard sized for iPad, all the objects on the viewController fill only the top/left area of the screen.
What's the best way to handle this?
-- when you change size of view, other view will be auto change to {0,0,0,0}, isn't ?
but it doesn't change in the right panel.
it is your storeboard files some settings have some wrong.

Check for those points:
hope this can help you.
I need to take a screenshot of whole storyboard as an image. Is that possible? I need it to give to my designer.
Ideally I'd like to get 1 big image, make some changes (number views, etc) and save it as JPG
Xcode doesn't have any features for printing or exporting an image of your storyboard. (Though that might make a good feature request to send to Apple.)
Your best bet is to resize your project window as large as possible (and hide the navigator and utility sidebars) and take a screenshot. You might be able to employ a trick or two in getting everything to fit:
If you're on a Mac with a Retina Display, change your screen resolution to one of the "more space" options so your Xcode window can be bigger. (For example, on a 5K iMac you can choose the "looks like 3200 x 1800" size, which renders a 6400 x 3600 screen and downscales it to fit the actual display hardware.)
Zoom out on the storyboard with the Editor > Canvas > Zoom menu commands. In Xcode 8, the zoomed-out storyboard uses the same rendering/editing engine as the regular-size view — which means that on a Retina display, your shrunken-down views will still be legible.
Resize the window larger than the screen, then take a window screenshot (Cmd-Shift-4, then spacebar, then click the window). You can do this with AppleScript:
tell application "Xcode" to set bounds of front window to {0, 0, 4000, 3000}
But that'll still limit its height to that of the screen (minus menubar and Dock). You can drag the window to the bottom of the screen and edge-resize it upward to get some extra height, though.
One more thing: Since the beginning of storyboards (way back in Xcode... 5, I think?), you've never needed to have "one storyboard to rule them all" in your project. In fact, there are lots of reasons why it might make sense to break your app into multiple storyboards. And of course, if you have multiple storyboards, you can screenshot them separately and integrate them however you like for a design presentation.
Using multiple storyboards used to mean you couldn't segue between view controllers in separate storyboards (you'd have to instantiate and present view controllers programmatically), but since Xcode 7 you can insert a "Storyboard Reference" in one storyboard to link to a view controller in a different storyboard. And if you have a big storyboard you want to break up, there's a tool for that. (Select some view controllers, choose Editor > Refactor to Storyboard...)
I have quite a large storyboard with many views, a lot of them do not display at the correct size or even have a navigation bar. Is this some kind of bug in XCode?, because they all look fine when simulated or built to a device.
Thanks
I have faced it lot of time below solution works every time.
Try This One:
1. Select the StoryBoard you are facing problem
2. Goto Attributes Inspector -> Simulated Metrics -> Size -> There are four options(default is inferred)
3.Select or switch between options other then default(repeat it twice or more if needed) then resize your views and controls to fit your selected screen size.
According to me this happens because:
Sometimes inferred (size) behaves as if its an 3.5 retina screen but our storyboard size is retina 4 full screen or vice-versa
Best Practice to avoid such problems :
When you start working with storyboard first select appropriate size you want to work with (3.5 or 4 full screen) then only you should set your views or controls.
I had this issue when embedding Container Views into the same View Controller.
With three Container Views embedded I found that Xcode auto-sized two of them when I selected "Apply Retina X.X Form Factor" but the size of the third was left untouched.
Solution
In the parent View Controller the third Container Viewer was missing constraints. Adding those constraints got every thing straight. (I also had to size the Container View to fill its parent Controller Viewer)
This is a very simple step. After selecting View Controller, go into your Simulated Metrics and select size and place it on iPhone 4-inch and then select Orientation and place it to Portrait and there you have it. Your main storyboard metrics are fixed. Again this is very important to know that this will not mess up anything your height or width in your project
