If using the latest Xcode 7 (Xcode 7 GM seed) I perform these steps:
1) Create new project / single view application
2) Disable size classes
3) In the storyboard add an image view as a child of the main view
4) In the storyboard provide an image for the image view
5) Run on a device with iOS 9
When the app launches the image is displayed for about 2 seconds, then the view goes white.
What's going on? I literally have done nothing other than the 5 steps above. Why is the image initially appearing then disappearing.
This is 100% repeatable, I can create any new project, add a image view, same effect.
Bug with Xcode, iOS 9? Surely this would have been noticed by now, 7 & 9 are both advanced now. What else then?
[And for any overzealous jobsworths out there, no I don't have any code to post, I haven't written any, its all boilerplate]
I found the problem:
When you create a template project with Xcode 7 in addition to the Main.storyboard file there is also a LaunchScreen.storyboard file created.
I didn't realize - I just saw the .storyboard extension and didn't see that there were two.
So what I was actually doing was adding the image view to the LaunchScreen.storyboard and not to the Main.storyboard.
Doh.

I have an old project that I've been working on and off on for about 4 years now - the project has gone through many upgrades of XCode versions from 6 to 10 (I'm now using XCode 10.2.1 with 12.2 SDK). The main problem I'm having with it is that it utilizes a Tab View Controller to switch tabs, and no matter what I do, I cannot get the tab bar to appear on the bottom of an iPhone X family device correctly: it appears much higher than it should.
To try and finally narrow down the problem, I've essentially temporarily "replaced" all code and storyboard items from the project to see if anything will move the tab bar to where it's supposed to (if I just create a blank new project with a tab bar controller, the tab bar does appear where it should). I created a test storyboard with just a Tab Bar Controller going to one navigation controller (no constraints have been put in). There is no viewController codes attached to them. I've replaced the app delegate with a "blank" app delegate so there are essentially no extraneous code or restraints there at all. And I still get the tab bar moved:
This happens on the simulator and the device, and there is no code or storyboard setting that's doing this (this same setup on a new project puts the tab bar in the right place).
I've looked around in the Build Settings and other properties that I may have missed to see if I constrained something years ago that may affect this, and didn't see anything.
Is there anything I should be looking for in the project settings that would do this?
I don't want to rebuild the project in a new project - there are many linked libraries, certificates, cocoapods, storyboard items, and I know it would be horrible to try and put it all back in one piece.
My Deployment Target is set to iOS 11, Devices: iPhone, Base SDK: iOS
Any help would be greatly appreciated!
This is usually caused by not having a correct launch image for the iPhone X. The easiest way to fix this is to tell the app target not to use launch images (from the app bundle or from the asset catalog) but to use the LaunchScreen.storyboard instead. (If you don't have one, make one; be sure to set it as a launch screen storyboard by clicking Use As Launch Screen and configure your target to point to it. Examine a plain vanilla new project to see what I mean.) You might not want to keep things that way in the long term but at least it will allow your app to launch to the correct size on all devices.
One of my iOS project is working fine for iOS 10. But when I run same code on iOS 11 Simulator build with Xcode 9, all UIImageView's images of my projects is not showing on simulator and device too, Background image on Button and cells are showing but Normal UIImageView is disappearing from Controller. Even it's not showing Background Color on that Image View.
What I did to resolve above issue are mentioned below:
Clean Build Uninstall App from simulator,
Cleared Derived Data and Archives
removed and added images again with copied target.
Added images in Images.xcassets with all three sizes.
Removed auto layout/Constrains and also added Auto layout/Constrains to check above scenario.
Created a fresh View Controller and added images and also added background color on that, its showing in Storyboard but when I run the Code its dis appears from Simulator and also from device.
All above mentioned points or solution are not working in my case.
check this image for Debug View hierarchy: And I am assuring, images on that ImageViews are copied to target.
Here is a before and after of one of my screens after I upgraded to Xcode 8.All I did was open up my main.storyboard and from there, I built and ran my app on my phone.In my version control, I can see Xcode is doing a lot of changes to my main.storyboard just from me opening it. Whenever I delete those changes, I can see what I use to see in Xcode 7.3.1.But, as soon as I re-open interface builder with my storyboard, I see those changes come back into place. Is there something I can do here?
Before Xcode 8
After update to Xcode 8
I had a similar problem with tableview images not appearing once I converted the storyboard file to be Xcode8 compatible. This looks like a bug with Xcode8, so until a bug fix is released, here is a work around:
Open your storyboard in Xcode 8 and choose an initial device view. Make changes as you normally would.
Once you have completed your changes, select the storyboard -> File Inspector -> Opens in -> Select 'Xcode 7.x'.
Select 'Save and Close' when prompted
Your storyboard changes will be saved, and your storyboard will function as it did pre-Xcode8.
When you need to make other changes to the storyboard file, follow these steps again.
XIB or Storyboard set default as older version 7.x and Save and Close. Temporary solution, but works. Don't open again once you have done Save and Close. Otherwise again need follow same steps from begin.
Eh the same problem. I partially managed to fix it in the following way (for Xcode Version 8.1 (8B62))
In the document outline of Storyboard, I clicked on each scene which had the yellow arrow indicating some layout issues (Number 1 on the screenshot)
After this, for each problematic scene, I had to click on "Update Frames" small icon (Number 2 on the screenshot) which fixed all the layout issues per scene.
However one scene in my case was still in crying state after transition from Xcode7 to Xcode8. I had to fix it manually by adjusting constraints or adding missing constraints.
Phew, not nice surprise of XCode8 and Storyboards. If you used AppCode editor, you won't have such problem, since it doesn't support Storyboards ;P
Good luck!
Xcode 8.1 Beta 2 resolves this issue. Please check this download link
https://developer.apple.com/download/
Please follow the threads for any possible solution:(I believe it happens to many developers).
Xcode 8 GM seed Storyboard issue
Xcode 8 - Previous storyboards getting distorted
(I used anyH anyW width 600) When Xcode updated to Xcode 8 it changed all my ViewControllers size. As a result all the layout was distorted.
Currently I see only 3 solution for the issue (I wouldn't trust on waiting for fix soon).
1.Go for each Viewcontroller and fix it it by Update Frames.
2.Go to the main ViewController Size Inspector -> Freeform -> 600 as most of the controllers are inferred it will change the size for
all of them.(Be careful on the impact of new Features Apple my want
to introduce).
3.Discard the changes in git for the storyboard (I would't suggest it because Apple also inserted some updates which may be important to
Xcode).
Additional link for the new AutoLayout features in Xcode 8 (WWDC16):
Making Apps Adaptive, Part 1
In my case works solutions suggested by Akhil Kateja and I also need to reset Width and Height of the main view:
1) Set View Size to Free Form
2) Reset Width and Height of the view to the original size:
Finally save and you are done.
For me the solution was simply to click on the UIViewController having issues and then Editor > Resolve Auto Layout Issues > All Views In ... > Updates Frames
It re-arranged the views to fit the existing constraints based on the newly selected default view (iPhone 7 in my case).
Also note: if you get a Navigation Bar Misplaced View warning like I did, simply select the UINavigationController/UIViewController and then Attributes Inspector > Bar Visibility > Shows Navigation Bar - toggle it OFF and then ON again.
Setting View Size to Freeform from Inferred worked for me. It can be found under the heading Simulated Metrics in Attributes Inspector.
I had the same problem and I've solved it by force update the controller's view constraints. Put the following code in your viewDidLoad() function
self.view.layoutIfNeeded()
I selected each controller and clicked on "Update Frames" and it fixed the layout.
The answer from #david-truong (https://stackoverflow.com/a/39589860/1407528) is not working in my case, so if you are in my same situation, try this:
Download the previous Xcode 7.3.1 from here: https://developer.apple.com/download/more/
Undo all your changes (if you have a code manager like git. If you don't, you should 'https://githowto.com/')
Open the project with Xcode 7.3.1.
In the case you have all your devices updated to iOS 10+, this version of Xcode will not recognize those devices as compatible devices. So, try with this trick:
Go to: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Copy the folders related with iOS 10 or 10.1 to: /Applications/Xcode 7.3.1.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
Open the project with Xcode 7.3.1 (restart Xcode if you have it already opened)
Select your connected iOS 10+ device
Push Run
Note: New features like Swift will not be available using this trick, but you should be able to load and build your project.
Hope this will help
When i updated Xcode from 7.3 to Xcode 8 and run the app, some of the views are perfectly displayed but some are distorted.Then, i checked the nib file and it prompted me to choose particular device size and then show the nib according to that device size which is offcourse not Any-Any(Xcode 7.3). So all the nibs file are not displaying in a correct way.
Solution work form me :- press the yellow arrow like showing in image below
it will prompt a pop up which show options like
choose Update Frames with Apply to all views in container checked.it will solved around 90% of distorted UI and rest of the auto-layout constraints problem can be solved manually.
I fixed the issue using the Xcode Version 7.3.1 you can download the .dmg file from apple developer portal. I used the Autoresizing in every app and it works great for me.
i will update to Xcode 8 only if they can fix this bug.
Download it here: https://developer.apple.com/services-account/download?path=/Developer_Tools/Xcode_7.3.1/Xcode_7.3.1.dmg
To fix a similar problem, I configured the xib as Freeform (not Inferred) AND saved xib file as Xcode 7.x compatible. Both steps were required in my case. I hope that helps!
I notice one new button in Xcode 8.2, (check the orange circle in the image). It will give you some help.
Steps:
1. Open the storyboard and select any device you want
2. Just select the View Controller
3. Click the mentioned button (as in Image)
4. It will updates the frame for that view controller and you can proceed with it
I didn't found any better solution than this. Please reply if found one.
update constraints and layout subviews in viewdidload solves the problem
- (void) viewDidLoad {
[self.view updateConstraints];
[self.view layoutSubviews];
[super viewDidLoad];
}
I'm trying to use Xcode's LaunchScreen storyboard as my launch screen? All the questions that have previously been asked about this refer back to the old launch image or .xib method - trying to do it now with the new LaunchScreen storyboard that Xcode automatically generates instead. I've selected the LaunchScreen storyboard as my launch screen file in my Deployment Info:
The storyboard itself confirms that it is set as the launch screen in it's file inspector.
And the info.plist file reflects this as well.
And yet, it doesn't work. The LaunchScreen storyboard never shows - it just goes straight to the first screen in my main storyboard. Using Xcode 7.2 and deploying to iOS 9.
Enable these two settings for the LaunchScreen.storyboard
If you are using xcode 11.2 you'll need to remove the app and execute it again to see the launch screen. I have to do this every time I modify the launch screen in order to see the new changes.
Another thing to make sure is that Launch Screen File is set to Launch Screen.storyboard
**Delete the app from the device. Re-run. **
In my case I had all the suggested settings set correctly but continued to have the original blank launchscreen. In the spirit of AmJa's suggestion regarding a "cache" problem, I deleted my app from my device and reinstalled. Reinstalling did the trick for me on both my devices and simulators.
In case anyone else runs into this issue, I resolved it by simply deleting the ViewController on my LaunchScreen storyboard (leaving me with an empty storyboard), creating a new ViewController and resetting the Storyboard entry point to that new ViewController. There may be some sort of bug with XCode 7.2 with respect to the LaunchScreen storyboard and default entry point into the auto-created View Controller, but then again, I've tried replicating this 3 times and it hasn't ever repeated itself, so maybe not.
In storyboard, in ViewController scene, I had to check Is Initial View Controller for storyboard to be seen as Launch Storyboard.
Suprisingly this is not checked when you add first View Controller. Xcode 11.
Just in case it helps someone.
Scenario, I created my new project and copied a old Launch Image from another project. And then started getting the launch image but when I wanted to change it to new image then still i was viewing the old image it was stuck for ever as launch image no matter what I do.
Then I reset my Simulator and restarted my iPhone and there you go I stared getting the new image. This looks like that somewhere in the documents or cache the devices store the old image until you reset the phone.
Thanks
As #abanet, mentioned in his answer, anyone who uses Xcode 11.2 and above, they have to delete their app and launch it again to see launch screen changes. It's not reflecting immediately. It looks like a bug from Xcode definitely not an intension.
How to fix for Xcode 11.0 and above:
Do this: https://stackoverflow.com/a/41287094/2190175 if you haven't already, and after that:
Delete app from device / simulator
Restart device / simulator
Reason: Launch Screen part of storyboard is cached during development and doesn't change until you remove app from device / simulator and reinstall it completely.
Other solutions didn't work for me, but this did:
Toggle on and off Device Orientation (e.g. support Upside Down) and Hide Status Bar in General.
I'm not sure which one did the trick, but it's working now.
If you don't see anything and your Launchscreen.storyboard only has an ImageView in it, then it might actually be showing the storyboard but not the image. Try putting a button in it or something. I've discovered that my Launchscreen.storyboard is actually showing but won't show any images and I don't know why.
The issue can be also that the "LaunchScreen.storyboard" is not added to this target.
To fix this open "LaunchScreen.storyboard" then press on "File Inspector" and under "Target Membership" add it to the needed target.
I tried everything mentioned here, the only thing that worked for me was creating a new LaunchScreen file. I'm using Xcode 12.1
(Don't forget to update the reference in the targets settings)
I was banging my head against a wall with this since Xcode 10.1 does not include a launch option for the new 11" iPad Pro when you create a new iOS Launch Image set, and without it, the iPad Pro doesn't display correctly, leaving me no choice but to get this working with a Launch Screen storyboard.
I tried combinations of so many things, but I wanted to post what ended up making it work 100% of the time (which was, in fact, a combination of a number of things).
As you have no doubt read, for the UIImageView within the Launch Screen storyboard, you should NOT include the extension (.jpg or .png). So many posts say that, but leave out that the reason is that you should create a new image set within Images.xcassets (NOT Launch Screen image set, but just image set) and name it whatever you want (for instance, "Launch-Default"). Then, drag and drop the desired .jpg or .png into the new image set. You will then use the name of that image set within the UIImageView in the storyboard and everything should work fine (the image should even show up inside of Interface Builder).
Also, within the General settings for the project, make sure to set the Launch Screen File to your new storyboard.
You need to add App orientation specific Launch Screen.
LaunchScreen Portrait: https://app.box.com/s/hfoeuvsy68iu913keb8p5hs1z9fdz3jk
LaunchScreen Landscape : https://app.box.com/s/o9q5nkrvk2ewdh57oiiar85zf658olgj
Drag LaunchScreen.storyboard & LaunchScreenBackground.png to Xcode sidebar. Then specify LaunchScreen in Xcode General page. See attach image
In my case, the problem was that the image for the logo was taken from a different target. Make sure that the image is from the main target of the application, and reset the simulator via menu Device/Erase All Content ad Settings...
In my case a few image views cover the whole parent view of the launch screen (e.g. pinned to the view edges). I had to uncheck the Resize view from NIB in the Attribute inspector for the launch storyboard and finally it worked for me (just do not forget to manually delete the old app from the simulator)
In my case the background color of the view (full screen) was set to a "missing" color literal! After trying all above of course ;(
A jpg image does a problem change the extension to png or use another png image
Worked like a charm for me
in xcode9 swift4 LaunchScreen storyboard, use .jpg image & uncheck clear graphics context for imageview. it's absolutly working.
I have worked on this application, done 2 years back, using XIB's and Autosizing.
Now, I've upgraded this app (in Xcode 5) & I need to make changes according to iPhone 5 (4") and iPhone 4, 4s (3.5")
I've tried to put Margin layouts but these are not making any difference.
I've created quite a few apps before using similar techniques with out any complication but in this app, the view in iPhone4 has a black cut at the top and bottom of the screen.
![enter image description here][2]
This issue is not related to AutoSizing.
You're just missing the 640x1136 launch image (i.e. Default-568h#2x.png).
Add it and your app should go full screen.
PS: This happened to me when I created an iOS7 project in Xcode 5 and deleted Images.xcassets from the project targets.
