Having a weird problem and can't find anything after over an hour of searching.
I am using Xcode 8 but also experience the issue when using Xcode 7 (I copied the project directory and tested in Xcode7 - I am working in Xcode 8 and created the project in Xcode 8, I only did this for testing purposes) to run the project in the simulator. I have no code in the view controller at this point so I know the problem is not related to code.
I have a simple view created in a storyboard but when I run it on any 8.1 simulator or device the logo appears stretched/skewed.
The original image is below:
I have created this simple placeholder image to make the point, originally I was using our company logo - so I know it's not an issue with the image since this one was just created.
I have tried removing all constraints from the image and just using width, height, and position constraints but the issue still persists.
Has anybody seen this happen before? What do I need to do to fix this?
you may change the uiimageview's view mode to "Aspect Fill" or "Aspect Fit" in the utilities area .

I have this project that is not using storyboards when I run it on my iPhone simulator it is not coming up full screen ?
From the viewcontroller property inspector select the presentation and set it to full screen it will work check the below image
check the content mode it should be scale to fill and size as freeform
Add below image to your project. Using the name Default-568h#2x.png
Because Xcode doesn't know your app size so this will pickup smallest size 320x480. With this image and name I suggest above, Xcode will recognize your app support bigger size.
Don't worry when running your app in smaller device, it's still OK.

This might be related to issue in launch screen. I also setup the project without storyboard but deleted the LaunchScreen.Storyboard as well and ended up getting the same screen as yours. After I recreated the project but leave the launchScreen file i was able to get the full screen display for my viewcontroller
Recently we switched to Xcode 6, and I am having this issue: my simplest tabbed app compiled with Xcode 6 occupies just part of the screen, when it runs on iPhone 5s. There are two black strips sitting at the top and bottom of the screen. Like below:
By default, it looks that way (that is, I created the project using Xcode's template, and compiled and ran it without any modifications). I have also tinkered with various project setting bits, but in vain. Tried creating the project in both Swift and OC, both had the same issue. Never had this problem in Xcode 5.
Can anyone tell what's going on here?
Thanks.
Set up launch images in your app. It is mandatory now for ios 9. Refer this https://stackoverflow.com/a/18913189/3051458
This happens when you dont have the right image assets in your project.
Correctly again drag drop the correct image assets in your project (check the splash images) and it will work.
Dont know why this happened but I suffered from this too ones and then saw the splash images got deleted.
I know this question may seem like a duplicate of a few existing ones but its not.
I am struggling with this issue where universal (iPad/iPhone) application does not display the splash screen anymore.
Before upgrading to iOS 9 and Xcode 7, no such issues were present. After upgrading no changes were made to the splash screen in any way.
Tech data relevant to the question:
Supported devices are iPad (landscape only) and iPhone
(portrait/landscape)
I use "Launch Screen.xib" that has an UIImageView with size classes and
constraints set up so that it's always full screen.
I have added all splash screen images in image assets (except iPad
Portrait ones)
I use Xcode Version 7.0.1 (7A1001) and iOS 9.0.2
This issue does not happen on an iPad
The wrong splash screen looks like this on iPhone 5s:
This is made in portrait mode, so there are white squares on top and on bottom of this "black square".
I was struggling with this issue yesterday but I managed to fix it by renaming my launch screen to "LaunchScreen.xib" (without the space). But this morning the issue re-appeared.
Things I've tried:
Removing and creating LaunchScreen.xib again with and without space
Creating LaunchScreen.storyboard file instead of xib
Adding #2x and #3x versions of image used in LaunchScreen.xib
Removing/adding/replacing images in image assets
Cleaning, build cleaning and even deleted derived data
Restarting device, reinstalling app, relaunching without building and many other solutions that I could think of.
Nothing helped, so maybe someone fixed a similar issue already and can lead me to the right direction.
EDIT 1
So I renamed my LaunchScreen.xib image used from "Default.png" to "DefaultSplash.png". This instantly fixed all issues on iPhone. But now I have a new problem - iPad splashscreen is now black. If I set the LaunchScreen image to some other image used in project, the Ipad displays it as splashscreen without any problems, but neither Default.png nor DefaultSplash.png can be used on ipad now. This is really weird issue.
In my case the images in the "Launch Screen.xib" weren't displaying. I had to rename them and reset the new names in the nib file to make it work.
So I fixed the issue like this:
Since I renamed the file LaunchScreen.xib, it fixed an issue on iPhone but caused a similar problem on iPad. Since then, I cannot use the same image file name for the same xib (i.e. if image "Default.png" failed, it cannot be used anyomre... Bug?). So I created two files, LaunchScreen.xib and LaunchScreen~iphone.xib with separate image files for each. Now it works okay.
Seems ugly and buggy but it works.
There is a change in Xcode7 iOS 9 onwards. They have modified Launchscreen(Black screen we will get).If you change deployment target means you can see the previous launch screen. Only empty view controller is present so we have make changes on it.
As per requirement in assets add images in imagecassets.
It may sound stupid but something related to this scenario may happen:
If you hook any outlet and then break it by changing the custom class you will get this black screen behavior without any warning, instead of the typical crash from any non launch storyboard/scenes this will lead to a black screen before the app start.
Most of my apps scale up when run on an iPhone 6, but for some reason one of my apps looks like this:
What would cause it to not just scale up and fill the screen?
EDIT: Here are some repro steps:
Create a new project (Single View). Turn off size classes and just use iPhone.
Make the background orange.
Add a yellow UIView subview at (20,20,280,200).
In Xcode you get this:
Now simulate on iPhone 6. You get this:
Why doesn't it just scale up and look normal?
Not sure why this is getting downvoted. It's a legitimate question. And here's the legitimate answer:
Remove the "Launch Screen File" in Projects > General. Xcode 5 did not have this so older apps scale up automatically. Apps created with Xcode 6 get a default Launch Screen file created.
Removing it will make your app scale up on iPhone 6.
I have got the same problem and I managed to solve it by adding constraints to my ViewController in the storyboard.
Make sure that you clicked the ViewController of your scene. They yellow button in the this screenshot.
Click Editor-> Resolve Auto Layout issues -> Add Missing Constraints
Now you will find that the background image is scaled up to fill iPhone 6 or iPhone 6 plus.
Note that this solution works for me even if I did not provide any launch screen file.
I had the same issue. Searching for an answer, most of them mention the launch image. To me, what did the trick, was that I first enabled launch image for iOS8.0 and later in Xcode, which requires the native resolution sizes for 4.7" and 5.5". Adding these sizes didn't help, but when I re-disabled them, it started working!
If you do have any launch image, you will need launch images for all appropriate sizes. I was doing a minor update to an app, and it was not showing correctly on the iPhone 6 simulator. I created four launch images (.png files). Since the app should still run on iOS 7, I apparently could not use an asset catalog. I gave the images the correct names, and all is good.

I have a view with some tableviews and some collection views and also some buttons and labels.
I'm not sure if this is new with Xcode 6.1 because I have not worked on the ui aspect of this project for some time. However, when I try to resize just about anything in the view, my tableviews and collection views, and possibly some other elements I am not noticing, get deleted. Specifically, it seems their frame or rect propertied get deleted.
To be clear, this only occurs when I attempt to resize the element by dragging the sides in interface builder. If I resize them by changing the numbers directly either in the IB sidebar or in the xml, this does not happen.
I'm wondering if this is a bug in Xcode or if I have done something to cause this behavior which I can change.
Thanks!
I acheived a fix, at least for this project by turning off auto layout in "show the file inspector" -> "interface builder document"
I have never used this feature in the past so I do not know if it was on in the past but I am wondering if the new Xcode version turns it on by default where the others left it off.
It may also be possible that it has always been on but there is a bug in the feature in the new version.
This fixed the issue for me, at least in this particular project and at least for now. I hope others find this useful.
From here it looks like a bug in Xcode 6.1.
I created a clean project and the behaviour is the same on my machine:
https://github.com/nasht/Xcode6ConstraintTest.git
Resizing one view makes others disappear. Changing a layout constraint from a = to <= or >= also seems to do it.
I've raised a bug with Apple. Suggest you do the same.
workaround: You can install xcode 6.01 and use interface builder from there. You can still compile and run your code using xcode 6.1 if you're relying on xcode 6.1 specific features. (you'll need to rename your xcode.app so you can run both instances. ) It's ugly, but it works.
I found that it's fixed on the next version of xcode (6.1.1)
same problem, yosemit and xocde 6.1. I can resize some view only if i disable autolayout.
I think I ran into this 'problem'. I believe this was because one of the constraints I had was not setup correctly.
What OS X Version are you on? I updated to Yosemite today and 6.1 along with it. When I would resize a label my other elements were not getting deleted but instead getting resized and repositioned. The width / height would change to 0,0 and the x / y would change to 0,0 as well.
I was noticing other issues with Yosemite so went ahead and did a time capsule restore back to Mavericks and Xcode 6.0
I had the same problem in universal app; iphone works fine and the ipad doesnt work.
I'm using xCode 6.1 and OSX Yosemite
My app supports iOS7 and iOS8 and i had the same problem on iOS7 on iPad version only
Fix:
So i fixed it by setting Simulated Metrics in interface builder by
Size = iPad Full Screen and Orientation by Landscape or Portrait
I have got the same kind of problem with Xcode 6.1 and Yosemite :
I have created a view that I have added to the main view, so it appears like a sub view in the View Controller Scene.
Then I resize this subview to 320 x 568. My program works. It corresponds to the program dropit of Stanford CS193P Lecture 9.
I save the project, close it and reopen it : the subview has its width and height set to 0 !
I tried to open the project dropit of Lecture 8 that is quite the same, which was working before (I think in Xcode 6) and same problem ! First I thought that tapping (related to the subview) was not working but found out that tapping was not working because I was tapping on a subview which has its width and height set to 0 !
I have reset the size class wCompact hAny to which all the UIElements are added. and got corrected.
